Human cells may not be unlike electric batteries. They from time to time have small energy retailers or can’t hold vigor. Micro Present-day Stimulation Remedy provides your cells with all the “energy” it takes, similar in order to recharging a new battery. Studies in addition have shown this MCS Remedy increases microcirculatory circulation, increases ATP concentrations plus stimulates amino acidity and source of nourishment concentrations directly into cells.
Every located cell inside body has a power charge. It is theorized that a part of what creates macular degeneration is usually a loss with the energy source inside cell, or losing the electrical charge. As being a flashlight will not likely work without getting a charged battery pack, the photoreceptors inside retina will not likely function not having an energy source. MCS Remedy is shown to increase the energy source within your cell.
This Macular Degeneration Foundation identified in starting pre-clinical trials by groundbreaking ophthalmologists plus researchers this micro present-day stimulation therapy can boost visual acuity, sharpness plus color perception in 68 percentage of individuals with dry out macular weakening and 58 percent of those with your wet kind. Reports from Russia advocate similar benefits.
A review published by way of Dr. Merrell J. Allen plus Dr. Leland N. Michael eligible Nutritional By using supplements, Electrical Excitement and Age Related Macular Degeneration showed this 60 percentage of individuals showed much better in visible acuity following combining micro present-day stimulation therapy and natural supplementation.
Drs. Leeway Halloran plus August L. Viewer studied 25 individuals declared with generally untreatable vision diseases including macular weakening, retinitis pigmentosa, CMV-retinitis, plus diabetic retinopathy. The individuals were handled with combining micro present-day stimulation therapy and natural supplementation. Overall final results showed outstanding increase with visual job in visible acuity in many and plainly established your safety with the combination of MCS therapy and natural supplementation.

FDA approves embryonic stem cells to reverse macular degeneration
by:Admin
Sacramento is now the hub of stem-cell research focusing on regenerative medicine. See the article, UC Davis: Stem Cell Research. After receiving $62 million for stem cell research last year, the new UC Davis Institute for Regenerative Cures opened. And the center already is testing dozens of therapies in the laboratory. The center will bring 200 scientists and laboratory personnel together under one roof. Check out the UC Davis Stem Cell Institute. See UC Davis Stem Cell Program. And check out the site, UCDMC Stem Cell Research News.
Now that the FDA has approved embryonic stem cells today, to help reverse certain types of macular degeneration, consumers should know that the stem cell taken from an embryo does not destroy the embryo. Just a single stem cell is taken from the embryo. Then the embryo continues to thrive and is not destroyed.
California sites currently under consideration for the trials include the Jules Stein Eye Institute at UCLA and the Ophthalmology Department at Stanford University. Check out the government site listing clinical trials, Clinical Trials.gov.
Also, in the Sacramento and Davis regional area, did you know that the University of California is recruiting for or has completed at least 193 clinical trials on various types of health studies ranging from the health benefits of ground flax seeds to stem cell research? Also see the January 4, 2011 news article, Read: Vitamin Drug Could Stop Dry Macular Degeneration.
Concerning studies at another university on macular degeneration and stem cell research, if you're interested in stem cell research for macular degeneration, the breaking news is that the FDA has just approved the use of stem cells to treat certain types of macular degeneration. According to a January 4, 2011 news article, "FDA Approves Stem Cell Treatment Trial for AMD-Related Vision Loss," the US Food and Drug Administration (FDA) has approved a clinical trial of human embryonic stem-cell treatments on patients who have suffered vision loss related to dry age-related macular degeneration (AMD).
Advanced Cell Technology of Massachusetts will begin a Phase I/II open-label study on twelve patients at multiple clinical sites to determine the safety and tolerability of the treatment. The dry version of macular degeneration is a leading cause of blindness in older adults. Dry age-related macular degeneration is one of two forms of an eye disease that breaks down retinal pigment epithelial (RPE) cells in the macula of the retina, a layer of light-sensitive tissue at the back of the eye. Progressive loss of RPE cells and the accompanying loss of photoreceptors can cause severe vision loss. There are no current treatments available for AMD.
Dry AMD is the leading cause of blindness in individuals over the age of 55, afflicting approximately 10 million people in the US. And as the population ages, according to the article, "FDA Approves Stem Cell Treatment Trial for AMD-Related Vision Loss."
In the clinical trials and approved experiments, patients will receive 50,000 to 2,000,000 RPE cells derived from human embryonic stem cells to replace those lost due to AMD. While human embryonic stem cell use is controversial, ACT maintains that their cells are derived from a single-cell extraction technology that “does not destroy the embryo.” Also read the article, Read: Smoking Raises Risk of Macular Degeneration.

Zinc and Macular Degeneration
By: Admin
Are you someone who has realized that they are suffering from age related macular degeneration?
Our sense of sight is something that is incredibly important to us, and the idea of having it threatened can be terrifying. The issue is that age related macular degeneration, often abbreviated to AMD is relatively common and after the age sixty, there is a thirty percent chance that this disorder can be developed and it is highly recommended that you use a antioxidant supplement as treatment/ therapy for macular degeneration.
The more research that you do into this condition and into the things that might have a hand in causing it, the more likely it is that you are going to see zinc listed as being something that can help this condition.

New Investment to Boost Gene Therapy Development
National Neurovision Research Institute (NNRI), the Foundation Fighting Blindness’ clinical trial support organization, announced today that one of its key partners, biopharmaceutical company Oxford BioMedica, has established a collaboration with sanofi-aventis, a major international pharmaceutical company, to develop and commercialize gene therapy treatments for vision-robbing retinal degenerative diseases that affect tens of millions of people around the world.
The collaboration will significantly bolster the development of the following gene therapy products: StarGen™ for the treatment of Stargardt disease, a form of early-onset macular degeneration; UshStat™ for the treatment of Usher syndrome, the leading cause of deaf-blindness; and RetinoStat® for the treatment of age-related macular degeneration, the leading cause vision loss in people 55 and older in developed countries.
The development of treatments for these and other retinal degenerative diseases is a key goal of the National Neurovision Research Institute and is the basis for its partnership with Oxford BioMedica. In 2006, Paul and Diane Manning, with the National Neurovision Research Institute, established a partnership with Oxford BioMedica to advance gene therapies for these and other related retinal degenerative diseases.
“The investment from sanofi-aventis is a wonderful boost for the development of Oxford BioMedica’s gene therapy products and will greatly enhance our ability to move these emerging treatments into and through the clinical trial process,” says Stephen Rose, Ph.D., chief research officer, Foundation Fighting Blindness. “This collaboration affirms the great potential for gene therapy to treat and cure a number of retinal degenerative diseases including Stargardt disease and Usher syndrome that, as rare diseases, often do not receive the attention or investment necessary to bring about promising treatments.”
“An important goal of the Foundation, through NNRI, is to attract investment from large pharmaceutical companies for the development and production of treatments for inherited retinal disease,” says Morton Goldberg, M.D., chairman of the board of NNRI. “The NNRI-Oxford partnership is an excellent model of how NNRI collaborations can accelerate the translation of laboratory-based research into clinical trials, ultimately getting successful treatments for rare diseases like inherited retinal degenerations to the market and out to the people who need them.”
Based on the agreement, Oxford BioMedica will receive an upfront payment of $26 million and a further $24 million from sanofi-aventis over a three-year period.
The treatments will utilize Oxford BioMedica’s LentiVector® gene delivery technology to deliver healthy vision-saving genes to the retina. For more information on this technology, visit www.oxfordbiomedica.co.uk/

German company's retinal implant can restore vision
by: Retina Implant
Restoring vision to the blind is the sort of feat reserved for ancient religious texts and modern science fiction novels. But a company in Germany did just that with an eye implant.
Retina Implant AG is in the process of developing a sub-Retina Implant, designed to be inserted into the eye to treat back-of-the-eye disorders. A first clinical trial showed that the device can enable people suffering from a certain type of macular degeneration to see. The patients had retinitus pigmentosa, an inherited and incurable degenerative condition that causes tunnel vision and often, eventually, complete blindness. Retina Implant estimates that the condition affects about 200,000 people in the U.S. and Europe.
In 1995, the company’s founder and current board member Dr. Eberhart Zrenner said that implanting a chip inside the eye was as far-fetched as using the space shuttle to get to an adjacent star in the Milky Way. But Dr. Zrenner, who is also chairman of the University of Tuebingen Eye Hospital in Germany, didn’t give up. Ten years later the company launched its first human trial. At the time, Retina Implant also began talking to venture capital firms in Europe, but the technology was deemed too risky. It wasn’t until a wealthy businessman, who was personally interested because he had relatives who suffered from vision loss, that the company found significant outside investment.
Retina Implant isn’t the only group working on bionic-eye-like projects, but it seems to have a jump on the competition. Scientists at the Mass. Institute of Technology are also conducting clinical trials with their own version of a sub-Retina Implant, but don’t anticipate implanting their device in humans until 2013. Sylmar, Calif.-based Second Site Medical Products Inc. is developing a device for sufferers of retinitus pigmentosa, but that’s an epi-retinal prosthesis used in conjunction with an external camera attached to eyewear.
Retina Implant’s product sits underneath the retina ’directly replacing light receptors lost in macular degeneration,’ according to the company. Its most advanced and studied sub-Retina Implant is a 3mm-by-3mm microchip with an array of approximately 1,500 photosensitive electrodes. Electrical power for the device is provided inductively through transmitter coils attached to the skin.
In November, the company published results (PDF) from the first in-human clinical trial that proved the device can work in the Proceedings of the Royal Society B, a peer-reviewed academic journal. The company’s research with 11 human subjects showed that people who had been completely blind had regained up to two percent of their vision. enough to recognize letters in a newspaper headlines and see utensils before them when seated at a table. That number may seem insignificant ’ but it’s impossible to calculate the value a blind person places on seeing again, no matter how dimly.
In October, Retina Implant announced that it would increase its manufacturing footprint 25-fold (PDF).
Retina Implant is in the process of commencing a larger, 60-patient clinical trial in several sites across Europe. In this trial, the subjects will have the option to keep the implant permanently. In the first trial, the chips were all removed after four months except for one patient who lobbied the government to allow him to keep the device because his outcomes were so positive. To date, no complications have been reported, according to the company.
Retina Implant believes its device can win CE Mark approval in the European Union as soon as the end of 2011, but it does not have yet have definite plans for entering the U.S. market.
MassDevice recently spoke with Retina Implant CEO Walter Wrobel about the difficulties of developing such a technically advanced medical device and his company’s efforts to prove the device’s effectiveness enough to get it to market.

Melatonin for Macular Degeneration?
By Cathy Wong, Alternative Medicine Guide
Melatonin may help treat age-related macular degeneration, according to a recent report. A leading cause of blindness in the United States, age-related macular degeneration develops when certain cells in the retina deteriorate and gradually destroy your central vision.
A hormone with antioxidant effects, melatonin may help stop shortening of telomeres (chromosomal structures that become shorter over time due to factors like aging, inflammation, and damage caused by free radicals). By preventing telomere-shortening in the cells of the retina, the report suggests, melatonin may help preserve eyesight and slow the progression of age-related macular degeneration.
While melatonin shows promise as a natural remedy for age-related macular degeneration, it's too soon to recommend melatonin supplements for this condition. For help in protecting your eyesight as you age, wear UV-protective lenses when outdoors in the daylight and consider upping your intake of foods rich in lutein (such as leafy green vegetables, green beans, and mango).
As always please check with your doctor before starting/ or changing any medications or supplements.

Acceleron's ACE-041 Demonstrates Clinical Efficacy
By Acceleron
CAMBRIDGE, Mass – November 19, 2010 – Acceleron Pharma, Inc., a biopharmaceutical company developing novel protein therapeutics that regulate the growth and development of tissues and cells, including muscle, bone, red blood cells, and vasculature, today announced the presentation of interim results from the first-in-human clinical study of ACE-041 in patients with advanced cancer at the 22nd EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Berlin, Germany. The presentation was given by Professor Sunil Sharma, the Jon and Karen Huntsman Presidential Professor of Cancer Research at the Huntsman Cancer Institute, University of Utah, Salt Lake City, Utah.
“It has been very encouraging to see so many signals of efficacy in this trial, in particular because these are end-stage cancer patients,” said Dr. Sunil Sharma. “It is also important to note that while we have demonstrated significant activity with ACE-041 monotherapy in this study, we might expect to see even more efficacy in future studies with ACE-041 used in combination with other therapies.”
“The clinical activity and safety profile of ACE-041 confirms our understanding that the ALK1 pathway plays a fundamental and distinct role compared to the VEGF-axis in tumor angiogenesis,” said Dr. Matthew Sherman, M.D., Chief Medical Officer at Acceleron Pharma. “This has significant implications because nearly all patients treated with VEGF inhibitors eventually either fail therapy or develop resistance to these drugs. There is a tremendous need for novel therapies that go beyond VEGF to target the tumor blood supply.”
In a phase 1, first-in-human clinical study, patients with advanced-stage tumors were treated with multiple ascending doses of ACE-041, to evaluate the safety and pharmacokinetics of ACE-041. This study also explored antitumor activity of ACE-041.
Summary of interim findings presented:
· ACE-041 subcutaneously (SC) injected once every three weeks (q3w) is generally well-tolerated · Common side effects include mild or moderate peripheral edema, fatigue, nausea, headache, anorexia, and anemia. A single case of Grade 3 congestive heart failure was reported · Toxicities commonly associated with VEGF inhibition (hypertension, proteinuria, or bleeding) have not been observed · ACE-041 pharmacokinetics support dosing every 3 weeks · One patient with refractory head and neck cancer achieved a partial response and three patients had prolonged disease stabilization · Rapid reduction in tumor metabolic activity observed in several patients, measured by FDG-PET imaging · An expanded cohort study is ongoing at the dose level intended for Phase 2 studies,
ACE-041 is being developed for the treatment of advanced cancer and age-related macular degeneration (AMD).
About ACE-041
ACE-041 is a recombinant receptor fusion protein that inhibits angiogenesis by preventing BMP9 and BMP10, members of the TGFβ protein superfamily, from interacting with activin receptor-like kinase 1 (ALK1), a receptor that is found on proliferating endothelial cells. ACE-041 inhibits ALK1 signaling, which is required for the development of mature, functional capillary networks. In animal studies, treatment with ACE-041 inhibits tumor angiogenesis and growth and ocular neoangiogenesis. In a clinical study of patients with advanced, refractory solid tumors, treatment with ACE-041 was generally well-tolerated and antitumor activity was observed, resulting in tumor shrinkage and stabilization of disease. ACE-041 is being developed for the treatment of advanced-stage cancer and age-related macular degeneration (AMD).

Macular Degeneration Treatments/Therapies Breakthroughs
by Isobel Washington
Macular degeneration is an eye condition characterized by the deterioration of the macula, which is the central "lens-like" part of the eye's retina responsible for sharp central vision. Affecting central vision and often leading to vision loss, macular degeneration has had limited treatment options. Recently, there have been some breakthroughs to help patients retain vision.
Significance
Macular degeneration is the leading cause of vision loss and blindness among Americans age 65 and older. Vision loss from this condition is a growing problem, since this age demographic represents an increasingly larger percentage of the U. S. population.
Function
Treatments for macular degeneration work to preserve vision ability at the time of treatment, and slow the progression of the disease (it's a progressive disease that affects vision over time). Treatment cannot restore vision that is already lost through the disease. There is no cure or treatment to stop the progression of macular degeneration, there are ways to preserve and prolong current vision.
Eye Injections
Lucentis and Macugen are FDA-approved ocular injection treatments, and are highly effective for preserving vision and inhibiting macular degeneration symptoms, according to AllAboutVision.com. A 2005 study on Lucentis demonstrated success rate of 95 percent for improving and sustaining vision in macular degeneration patients.
Laser Treatment
Laser technology is now used to destroy the abnormal, leaky blood vessels that cause vision loss in macular degeneration patients. The National Eye Institute points out, however, that while this treatment may be effective for preventing vision loss, it is also comes with the risk of destroying healthy tissue that surrounds the treatment area.
Photodynamic Therapy
This method uses special light treatment to activate an injected drug, verteporfin, in the blood vessels, so that it destroys the new, abnormal blood vessels being hyper-produced in the eye (those that cause vision impairment or loss). The National Eye Institute reports that this light-activation method slows vision loss, but doesn't stop it.
Investigational Treatments
Investigational treatments for macular degeneration, in various stages of research and FDA clinical studies, include Avastin, a cancer treatment drug. As of 2009, the National Eye Institute reports that no available treatment provides a cure for macular degeneration, and that vision loss may result, despite treatment.

Function
Treatments for macular degeneration work to preserve vision ability at the time of treatment, and slow the progression of the disease (it's a progressive disease that affects vision over time). Treatment cannot restore vision that is already lost through the disease. There is no cure or treatment to stop the progression of macular degeneration, there are ways to preserve and prolong current vision.
Eye Injections
Lucentis and Macugen are FDA-approved ocular injection treatments, and are highly effective for preserving vision and inhibiting macular degeneration symptoms, according to AllAboutVision.com. A 2005 study on Lucentis demonstrated success rate of 95 percent for improving and sustaining vision in macular degeneration patients.
Laser Treatment
Laser technology is now used to destroy the abnormal, leaky blood vessels that cause vision loss in macular degeneration patients. The National Eye Institute points out, however, that while this treatment may be effective for preventing vision loss, it is also comes with the risk of destroying healthy tissue that surrounds the treatment area.
Photodynamic Therapy
This method uses special light treatment to activate an injected drug, verteporfin, in the blood vessels, so that it destroys the new, abnormal blood vessels being hyper-produced in the eye (those that cause vision impairment or loss). The National Eye Institute reports that this light-activation method slows vision loss, but doesn't stop it.
Investigational Treatments
Investigational treatments for macular degeneration, in various stages of research and FDA clinical studies, include Avastin, a cancer treatment drug. As of 2009, the National Eye Institute reports that no available treatment provides a cure for macular degeneration, and that vision loss may result, despite treatment.

Novartis therapy Lucentis recommended for approval in EU to treat Diabetic Macular Edema
By Thomas Reuters
- CHMP positive opinion supports Lucentis approval in EU for treatment in patients with visual impairment due to diabetic macular edema (DME)
- Pivotal data shows Lucentis provided rapid, superior and sustained vision gains compared to the current standard of care
- Diabetes-associated eye diseases such as DME are a leading cause of blindness in most developed countries in the working-age population
Basel, October 22, 2010 - Novartis has received a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) for Lucentis(R) (ranibizumab) for the treatment of patients with visual impairment due to diabetic macular edema (DME), a leading cause of blindness in the working-age population in most developed countries.
"Lucentis was designed specifically for use in the eye, and its efficacy and safety have now been demonstrated in patients suffering loss of vision due to diabetic macular edema through a robust program of clinical trials," said David Epstein, Division Head of Novartis Pharmaceuticals.
The submission was supported by data from two Novartis-funded clinical trials, RESTORE and RESOLVE, which showed that Lucentis was superior in providing rapid and sustained visual acuity gain versus sham (dummy therapy) or laser therapy, the current standard of care. The RESTORE study showed patients treated with Lucentis alone or with Lucentis plus laser therapy achieved an average 5.9 letters and 5.5 letters gain in visual acuity at 12 months, respectively, compared to laser-treated patients as measured on a standard ETDRS eye chart.
The RESOLVE study showed that Lucentis-treated patients achieved an average 11.7 letters gain in visual acuity at 12 months compared to sham-treated patients, some of whom received laser treatment.
The pivotal data from RESTORE and RESOLVE are further supported by results of an independent US study conducted by the Diabetic Retinopathy Clinical Research Network (DRCR.net), showing that at one year nearly 50% of patients' eyes treated with Lucentis and laser therapy improved their visual acuity by 10 letters or more, compared to 28% with laser alone. In addition, the study demonstrated superior gains in visual acuity among Lucentis-treated patients up to two years.
Lucentis was generally well tolerated in clinical studies, either when given as monotherapy or when combined with laser treatment. Its safety profile was consistent with that previously reported in large controlled clinical trials, and in rigorous monitoring since Lucentis was first approved for wet age-related macular degeneration (AMD). Lucentis is currently licensed in more than 85 countries for the treatment of wet AMD.
Diabetic macular edema (DME) is a consequence of diabetic retinopathy - the most common diabetic eye complication, characterized by changes in the blood vessels of the retina - to the light-sensitive layer at the back of the eye. In patients with DME, leakage from these abnormal blood vessels occurs in the central portion of the retina, called the macula. Because this part of the eye is responsible for sharp central vision, DME can lead to significant visual impairment. Visual impairment due to DME affects approximately 1-3% of patients with diabetes, and DME is a leading cause of blindness in the working-age population in most developed countries.
Lucentis offers an entirely new pharmacological approach to treatment compared to the current standard of care for DME that involves the use of laser burns to stop the capillary leakage and to reduce swelling. Lucentis is an antibody fragment that is injected into the eye and acts by neutralizing vascular endothelial growth factor (VEGF), a protein that is known to increase vascular permeability, resulting in capillary leakage and macular edema in patients with diabetes.
Lucentis was developed by Genentech and Novartis. Genentech has the commercial rights to Lucentis in the United States where Lucentis is also approved for the treatment of macular edema following retinal vein occlusion (RVO). In addition, Genentech is conducting two Phase III studies, RISE and RIDE, in patients with diabetic macular edema. The results are expected in 2011. Novartis has exclusive rights in the rest of the world and plans to file in the European Union for approval of Lucentis for the treatment of visual impairment due to macular edema following RVO.

Complement inhibition may be the future of dry AMD therapy
CHICAGO — Ongoing clinical trials exploring the use of complement inhibitors for treating nonexudative age-related macular degeneration offer promise for a disease state that has long been considered difficult to treat.
A number of recent studies have implicated the complement immune system in AMD. However, nonexudative AMD remains a "uniquely human disease," and, therefore, no animal model exists in which to prove potential therapeutic strategies, Philip J. Rosenfeld, MD, PhD, said here are Retina Subspecialty day preceding the joint meeting of the American Academy of Ophthalmology and the Middle East Africa Council of Ophthalmology.
As a result, Dr. Rosenfeld said, human trials will prove important in determining whether complement inhibition is of any real clinical benefit.
Several such trials are already underway. Alcon is currently investigating its POT-4 (AL-78898A) anti-C3 cyclic peptide in human trials. There is some evidence that POT-4 may also affect VEGF expression in the retina, Dr. Rosenfeld said.
Separately, Genetech/Roche has an anti-factor D (FCFD4514S) that inhibits the C3 and C5 alternative pathway convertases. Phase 1 studies have been successfully completed with that agent, Dr. Rosenfeld said.
Two separate C5 inhibitors are being studied: Eculizumab/Sollris (Alexion) and ARC1905, an anti-C5 aptamer (Ophthotech).
"One of the advantages is that while you block the downstream activated species, you preserve the more proximal species that are important for the clearance of bacteria, particularly the encapsulated organisms," Dr. Rosenfeld said.

Macular Degeneration and your eyesight
You have most probably heard of this very common condition that damages your eyesight as you age. Because this condition affects more elderly people it is often referred to as age-related macular degeneration. Unfortunately there is no cure available for this condition however there are treatments that can help. This blog outlines the latest in research and treatments regarding macular degeneration and aims to help you make the most out of your eyesight in the mean time.
Now macular degeneration as the name implies affects the macula, which is an area right at the back of the eye on a structure that detects light known as the retina. Your macula is the part of the retina that allows you to see things in great detail. In fact many birds have better maculas than us, as they need to see things in great detail from up in the air. The condition of macula degeneration implies that the macula is damaged and as this damage becomes more extensive your eyesight will be affected. There are two types of macula degeneration and they are known as the wet or the dry type, the most common of the two is ‘dry’ maculae degeneration. In this type you get little yellow patches that pop up around your macula and your vision slowly worsens. In ‘wet’ macula degeneration there are tiny blood vessels in the back of your eye that grow and then leak out blood and other fluid. This tends to make ones vision worse more quickly and you should note that dry degeneration can turn into the wet kind.
Those who present with this condition for the most part have difficulty reading, making out fine detail and even have trouble recognizing friends and families faces. After a few years of having this condition things that are in the middle of your vision will begin to look blurred and you may struggle to make things out. After a while the middle of your vision may just appear black and you often cant see anything in this area, this means that you will be unable to see things that are right in front of you. However your peripheral vision will not be affected.
There are things that you can do to cope with this condition as well as medicines that can help. Your doctor may teach you how to make better use of your peripheral vision and tell you that using bright lighting in your home will help you see better. You may also need to make text on the computer screen bigger and use magnifying glasses when reading a book. Most of the medical treatments are aimed at the treatment of wet macular degeneration and in fact there are not many effective treatments for the dry variety. Laser therapy can be used to stop the macular degeneration from getting worse in the sense that these lasers burn away those yellow patches that form around the macular early in the disease course. Also there is no need to worry as laser therapy is not painful and is quite quick, however the evidence supporting this form of treatment is not great at this stage. In fact some research suggests that laser treatment can cause new blood vessels to from on the back of the eye that can make your sight worse.
Mineral and vitamin supplements may be useful in slowing down or stopping macula degeneration from occurring. You should take zinc, vitamin E and C as well as beta-carotene. Remember here that you will need to take them for a long time and in high doses to be affective and remember that these are not without their side effects. Some people find that they have problems with passing urine, others complain of stomach pains and some people notice that their skin turns a little yellow. If this is that case with you then you should stop taking the tablets and visit your doctor.
Wet macular degeneration can be treated with photodynamic laser surgery whereby a dye that is sensitive to light is injected into your bloodstream and then a laser is shone into your eye. The dye that was injected into the blood helps the laser to destroy all of those leaky blood vessels that are damaging your eye. This method has mixed reviews on effectiveness and one should have a good discussion with their doctor regarding the risks and benefits of this procedure before having it done.
There is another type of laser that can be used to destroy the blood vessels in the eye that leak, but this is only affective in a few people with very severe disease. There is a chance with this procedure that the blood vessels will grow back anyway and the laser can sometimes damage the eye. Radiotherapy is another option but lacks suitable research to say whether or not it works and we always worry that radiation may damage other parts of the eye.
There is an injection that you can have in your eyeball called pegaptanib, however for obvious reasons not many people like the idea of this if they can help it. Also you have to have two injections every month and the evidence is not great that it works wonders, although there are some convincing studies. There is another injection called ranibizumab that you get in your eyeball and this also does not have great results but is indicated in people with wet macular degeneration that is getting worse.
So the most important thing is what will happen to you and in this case the outcome is not fantastic. Over many years your vision will gradually get worse and it will be much worse in the centre of your vision than in the peripheries and you are unlikely to go completely blind. Unfortunately we don’t know how quickly things will turn bad and each patient is different, but most people manage to get around even with severe disease as they are able to use their peripheral vision much more effectively.
Now macular degeneration as the name implies affects the macula, which is an area right at the back of the eye on a structure that detects light known as the retina. Your macula is the part of the retina that allows you to see things in great detail. In fact many birds have better maculas than us, as they need to see things in great detail from up in the air. The condition of macula degeneration implies that the macula is damaged and as this damage becomes more extensive your eyesight will be affected. There are two types of macula degeneration and they are known as the wet or the dry type, the most common of the two is ‘dry’ maculae degeneration.

Drug Research could lead to AMD therapy
By Adrian Galbreth
New drug research may pave the way for more effective treatments of age-related macular degeneration - the leading cause of blindness in the western world.
Those are the claims being made by researchers at Tufts University School of Medicine, who say that a protein known as galectin-3 promotes the growth of new blood vessels, and that targeting the protein can "significantly reduce" angiogenesis.
The findings have been published in the Journal of Experimental Medicine and may lead to treatments for diseases caused by excessive angiogenesis, which include AMD, said Dr Noorjahan Panjwani, who led the project.
She explained: "Our study shows that galectin-3 protein binds to glycans of specific cell-adhesion proteins to activate the signaling pathways that bring about angiogenesis. This improved understanding may provide a more targeted approach to preventing harmful angiogenesis."
Meanwhile, another team of researchers at Tufts have found that that non-viral gene therapy can delay the onset of some forms of eye disease and offer hope to retinal degeneration sufferers.ADNFCR-1853-ID-800028486-ADNFCR

Visudyne therapy
Age-related macular degeneration (AMD) is a progressive disease of the eye, meaning that it can’t be cured. The good news is that AMD can be controlled. Treatments available today can slow the vision loss associated with AMD and even restore some vision.
Wet and dry age-related macular degeneration (AMD) differ in several important respects, including treatment options. The only way to find out which AMD treatment regimen or management plan is right for you is to talk to your ophthalmologist or retinal specialist.
Visudyne therapy treats a form of AMD called predominantly classic subfoveal CNV due to AMD.
In this form of AMD, abnormal blood vessels leak fluid and/or blood under the macula—the part of the eye responsible for central vision—causing serious vision loss. During therapy, Visudyne is injected into the patient (generally through the arm). Next, light from a low-energy laser activates Visudyne, causing it to destroy the leaky vessels. As a part of a wet AMD treatment regimen, Visudyne therapy may help slow its progression.
Ask your ophthalmologist or retinal specialist if Visudyne therapy may be right for you.

Medicine from Moss to produce human protien
Diabetics use human insulin produced in bacteria in order to treat their metabolic disorder. Many other genetically engineered proteins are also on the advance. They are being used for diagnosis as well as for therapy.
Whereas insulin used to be extracted from slaughterhouse waste, today it is produced genetically in bacteria. However, more complex proteins have to be synthesised in more complex organisms. This takes place mostly in bioreactors using animal cell lines. Biotechnologist Prof. Ralf Reski from Freiburg, Germany, has developed the moss Physcomitrella patens into a safe and inexpensive alternative supplier of medicine.
His group has now, under Dr. Eva Decker, for the first time succeeded in producing a human protein in a moss bioreactor, which has been assigned the "orphan drug" status by the respective EU authorities. This means the development and approval of such medication receive particular support from the authorities. In many people the amount of this protein decreases with old age - with severe consequences. Eva Decker explains: "With the complement factor H we have produced a protein in moss that otherwise occurs only in blood and is important for the immune system. Not enough of this protein in older people is the main cause of blindness for 50 million people worldwide. This age-related macular degeneration (AMD) is a problem, particularly in industrialised countries."
Biochemists from the Freiburg Centre for Systems Biology under Dr. Andreas Schlosser were able to show with the help of high-performance mass spectrometers that the human factor H engineered into and produced by moss was a complete protein. Infection biologists headed by Prof. Peter F. Zipfel from the Hans-Knöll-Institute in Jena, Germany, were able to prove in biological assays that factor H from moss is fully functional. "Currently factor H is not available in pharmacies, so treatment for AMD with this protein is not possible. To date recombinant production of factor H was barely feasible. I am convinced that for the first time the moss bioreactor is a promising option", says Peter Zipfel.
This work was supported by the German Federal Ministry of Education and Research (BMBF), the Freiburg Initiative for Systems Biology and the Cluster of Excellence BIOSS.
Dr. Annette Büttner-Mainik, first author of the publication, was a Kekulé scholarship holder from the endowment fund of the German Chemical Industry (FCI).

"It will take a while before medication produced in moss is available in pharmacies", says Ralf Reski, member of the Innovation Think Tank of the governor of Baden-Wuerttemberg. "We are further optimising the moss bioreactor using methods from Systems Biology and Synthetic Biology. However, the implementation of clinical studies and the setting up of industrial production is long-winded and expensive; this is the task of industry and not of university research."

Stem Cell Transplants Stalled Blindness in Rats
Researchers say putting nerve stem cells from StemCells Inc near the retinas of rats with a form of macular degeneration helped keep the disease from advancing to blindness for several months.Nerve stem cell transplants may help slow the progression of macular degeneration, the most common cause of blindness in the developed world, U.S. researchers said on Monday.
They said putting nerve stem cells from StemCells Inc near the retinas of rats with a form of macular degeneration helped keep the disease from advancing to blindness for several months.
"These cells improve the chemical environment in the back of the eye," said Ray Lund of the Casey Eye Institute at Oregon Health & Science University in Portland, whose findings were presented at the Society for Neuroscience meeting in Chicago.
Lund said the mechanism is not clear, but he suspects that when immature nerve cells are placed near the retina, they produce growth factors that protect the cells from damage by the disease.
"It's basically a chemical pump that is sitting in the right place and producing the right things," Lund said in a telephone interview.
Where normally animals with eye disease lost their vision by three months old, rats that got the transplants kept their vision for at least seven months, he said.
"There is no evidence that they (the transplanted cells) do any damage," Lund said, adding that the animals do not develop tumors, a key worry for stem cell transplants.
The findings raise hope for use of the treatment in humans with a range of diseases in which the retina become damaged, including age-related macular degeneration or AMD, which affects nearly 30 million people worldwide, including 15 million Americans.
People with AMD lose central vision when delicate light-sensing cells of the macula, a region at the center of the retina, become damaged.
In the rats, the researchers transplanted immature nerve cells into the space near the retina. Lund said the same could be done in people with retinal disease.
Dr. Stephen Huhn, head of the Central Nervous System research program at StemCells Inc, said the cells are adult neural stem cells. He said they are multipotent, meaning they can morph into different types of nerve cells.
The company has already tested the treatment in a study of six patients with Batten's disease, a fatal inherited disorder of the nervous system.
"Having a cell that has already entered clinical testing that has been well tolerated at very high doses in the brain gives us a lot of confidence about exploring the same type of strategy in the eye," Huhn said.
Huhn said he thinks the cells may be especially well suited for use in the retina, brain and spinal cord, which are less likely to reject the cells than other parts of the body.
Ultimately, he said the hope is to develop a treatment for the dry form of macular degeneration, which affects around 90 percent of patients diagnosed with AMD. No treatments are available for this form of the disease.
Huhn said treating this form of the disease may prevent some people from developing wet AMD, in which tiny new blood vessels grow between the retina and the back of the eye.
This form of the disease can be treated with modern drugs like Lucentis, from Novartis and Roche's Genentech, and Pfizer's Macugen.

Stem cell Therapy to Benefit Blind
Submitted by Jayden Roberts on Tue, 06/29/2010
Italian researchers have reported that about 12 people have regained their sight in a successful experiment conducted with some partly blind and severe eye damage suffering people. This was revealed in a study published online in the New England Journal of Medicine.
This is a remarkable success that will encourage the cell-therapy, which is done by transplanting cells from one’s own body to other parts. It has been claimed that the treatment has proved winning in 82 of 107 eyes. Also, it was partially complete in 14 others eyes. The benefits of the treatment are expected to last till 10 years after the process.
It is also noticeable that one man, who had been blind for more than five decades, have also completely restored his visual capacity. Appreciating the success, Ophthalmologist Ivan Schwab of the University of California praised and congratulated the team.
If the stem cell transplants become popular and are implemented even more, they can also prove helpful for the people who are affected by chemical burns on their corneas from heavy-duty cleansers and other chemicals. This will be a great help for people who have to suffer eyesight loss due to such mishaps.
However, the stem cell approach is not capable to treat optic nerve or macular degeneration, which is caused due to the damage in retina, as the treatment requires a few healthy tissues that can be transplanted.

Ann Arbor Pharma Firm Testing Zinc For Alzheimer's Treatment
Ann Arbor-based Adeona Pharmaceuticals Inc. (AMEX: AEN) Monday announced the completion of 50 percnet enrollment in Part 2 of its clinical study, "A Prospective, Randomized, Double Blind Trial of a Novel Oral Zinc Cysteine Preparation in Alzheimer's Disease (CopperProof-2)."
The CopperProof-2 study represents the first controlled clinical study of oral zinc cysteine for the dietary management of Alzheimer's disease and mild cognitive impairment.
Part 2 of the CopperProof-2 study is designed as a 60-subject comparator study. Subjects are randomized on a 50:50 basis to receive either Zinthionein ZC or matching placebo. After 3 and 6 months on clinical trial material, serum measurements of zinc and copper are taken, and any changes in cognitive function using standard clinical tests used in Alzheimer's disease and mild cognitive impairment are recorded.
The completion of 50 percent enrollment follows Adeona's April 14 announcement of positive results from Part 1 of the CopperProof-2 study. Part 1 demonstrated a substantially lower incidence of adverse effects in Alzheimer's disease and mild cognitive impairment subjects (33 percent versus 100 percent) in favor of Zinthionein ZC (containing 150 mg of elemental zinc acetate and 100 mg of cysteine) compared to Galzin (containing either 50 mg or 100 mg of elemental zinc as zinc acetate).
Zinthionein ZC also demonstrated superior serum zinc bioavailability in Alzheimer's disease and mild cognitive impairment subjects compared to both the 50 mg and 100 mg dose levels of Galzin.
"Having pioneered the use of oral zinc therapy in dry age-related macular degeneration, which has now become the standard of care, I believe that Adeona's once-daily, high bioavailability, well-tolerated oral zinc cysteine formulation has the potential to ameliorate the sub-clinical zinc deficiency in Alzheimer's and mild cognitive impairment subjects and substantially grow current markets for oral zinc-based therapies," said David Newsome, M.D., Adeona's senior vice president for research and development.
Added Adeona CEO James S. Kuo, M.D.: "We are pleased to have reached this enrollment milestone on a timely basis and within budget. Along with the recently announced Meda collaboration for flupirtine's development and completion of 50 percent enrollment in the Trimesta multiple sclerosis clinical trial, it represents one of several major transformational changes taking place at the company in the past few months."
Observations by Adeona scientists and other scientists of sub-clinical zinc deficiency in Alzheimer's disease patients plus a body of published literature that chronic elevated copper exposure contributes to the progression of Alzheimer's disease and mild cognitive impairment prompted the present CopperProof-2 clinical study.
Alzheimer's disease can affect the entire brain but it is particularly associated with loss of tissue in the hippocampus, the area in the brain responsible for several functions including short-term memory retention and processing. The hippocampus has one of the highest concentrations of zinc in the brain. Hippocampal zinc is thought to play a role in hundreds of protective enzymes and other systems, including those that detoxify amyloid beta, an abnormally folded peptide that accumulates in aging and is a biomarker for Alzheimer's disease. When cerebrospinal fluid zinc is low, levels of the particularly toxic beta amyloid 42 are elevated.
Hippocampal zinc serves as a neurotransmitter, and also modulates a specific neuroreceptor. If the neuroexcitation goes uncontrolled, there is a derangement of brain tissue function, and possibly neuronal death. By elevating cerebrospinal fluid zinc, the receptor excitation may be better controlled, improving tissue function and thereby acute cognition and tissue survival, as may have been seen in the 1992 study. NMDA-receptor antagonists now available for Alzheimer's, including Namenda and Axura, annually sell an estimated $2.6 billion.
Zinthionein ZC is a once-daily, gastroretentive, sustained-release, oral tablet formulation of zinc and cysteine. Zinc, an essential nutrient, participates as a necessary factor in the activity of over 200 enzymes and the DNA binding capacity of over 400 nuclear regulatory elements. Zinc may also directly participate in antioxidant protection by reducing the susceptibility of sulfhydril groups to damage by oxidative free radicals. Cysteine is an amino acid that has potent anti-oxidant properties and is a necessary component of the copper-zinc-binding protein, metallothionein.
Zinthionein ZC was invented and developed by Adeona scientists to achieve the convenience of once-daily dosing, high oral bioavailability and to minimize gastrointestinal side effects associated with other commercially available, oral zinc products. All of Zinthionein ZC's constituents have GRAS (Generally Regarded as Safe) status. Adeona is developing Zinthionein ZC as a prescription medical food for the dietary management of Alzheimer's disease and mild cognitive impairment. Zinthionein ZC is protected by multiple U.S. and international pending patent applications held by Adeona.
Adeona is a pharmaceutical company developing new medicines for serious central nervous systems diseases. Adeona's primary strategy is to in-license clinical-stage drug candidates that have already demonstrated a certain level of clinical efficacy and develop them to an inflection point in valuation resulting in a significant development and marketing collaboration.
Its other drugs include Trimesta (estriol) is an investigational oral drug for the treatment of relapsing remitting multiple sclerosis, currently in clinical trials, and Effirma (flupirtine), a centrally-acting investigational oral drug for the treatment of fibromyalgia syndrome. Adeona has entered into a potential $17.5 million corporate partnership with Meda AB. As part of the agreement, Meda will assume all future development costs while Adeona is entitled to receive milestone payments and royalties.

"Having pioneered the use of oral zinc therapy in dry age-related macular degeneration, which has now become the standard of care, I believe that Adeona's once-daily, high bioavailability, well-tolerated oral zinc cysteine formulation has the potential to ameliorate the sub-clinical zinc deficiency in Alzheimer's and mild cognitive impairment subjects and substantially grow current markets for oral zinc-based therapies," said David Newsome, M.D., Adeona's senior vice president for research and development.
Added Adeona CEO James S. Kuo, M.D.: "We are pleased to have reached this enrollment milestone on a timely basis and within budget. Along with the recently announced Meda collaboration for flupirtine's development and completion of 50 percent enrollment in the Trimesta multiple sclerosis clinical trial, it represents one of several major transformational changes taking place at the company in the past few months."
Observations by Adeona scientists and other scientists of sub-clinical zinc deficiency in Alzheimer's disease patients plus a body of published literature that chronic elevated copper exposure contributes to the progression of Alzheimer's disease and mild cognitive impairment prompted the present CopperProof-2 clinical study.
Alzheimer's disease can affect the entire brain but it is particularly associated with loss of tissue in the hippocampus, the area in the brain responsible for several functions including short-term memory retention and processing. The hippocampus has one of the highest concentrations of zinc in the brain. Hippocampal zinc is thought to play a role in hundreds of protective enzymes and other systems, including those that detoxify amyloid beta, an abnormally folded peptide that accumulates in aging and is a biomarker for Alzheimer's disease. When cerebrospinal fluid zinc is low, levels of the particularly toxic beta amyloid 42 are elevated.
Hippocampal zinc serves as a neurotransmitter, and also modulates a specific neuroreceptor. If the neuroexcitation goes uncontrolled, there is a derangement of brain tissue function, and possibly neuronal death. By elevating cerebrospinal fluid zinc, the receptor excitation may be better controlled, improving tissue function and thereby acute cognition and tissue survival, as may have been seen in the 1992 study. NMDA-receptor antagonists now available for Alzheimer's, including Namenda and Axura, annually sell an estimated $2.6 billion.
Zinthionein ZC is a once-daily, gastroretentive, sustained-release, oral tablet formulation of zinc and cysteine. Zinc, an essential nutrient, participates as a necessary factor in the activity of over 200 enzymes and the DNA binding capacity of over 400 nuclear regulatory elements. Zinc may also directly participate in antioxidant protection by reducing the susceptibility of sulfhydril groups to damage by oxidative free radicals. Cysteine is an amino acid that has potent anti-oxidant properties and is a necessary component of the copper-zinc-binding protein, metallothionein.
Zinthionein ZC was invented and developed by Adeona scientists to achieve the convenience of once-daily dosing, high oral bioavailability and to minimize gastrointestinal side effects associated with other commercially available, oral zinc products. All of Zinthionein ZC's constituents have GRAS (Generally Regarded as Safe) status. Adeona is developing Zinthionein ZC as a prescription medical food for the dietary management of Alzheimer's disease and mild cognitive impairment. Zinthionein ZC is protected by multiple U.S. and international pending patent applications held by Adeona.
Adeona is a pharmaceutical company developing new medicines for serious central nervous systems diseases. Adeona's primary strategy is to in-license clinical-stage drug candidates that have already demonstrated a certain level of clinical efficacy and develop them to an inflection point in valuation resulting in a significant development and marketing collaboration.
Its other drugs include Trimesta (estriol) is an investigational oral drug for the treatment of relapsing remitting multiple sclerosis, currently in clinical trials, and Effirma (flupirtine), a centrally-acting investigational oral drug for the treatment of fibromyalgia syndrome. Adeona has entered into a potential $17.5 million corporate partnership with Meda AB. As part of the agreement, Meda will assume all future development costs while Adeona is entitled to receive milestone payments and royalties.

Long-Term Bevacizumab Therapy in Macular Degeneration Patients Appears Safe: Presented at ARVO
By Micheal Casasnovas
Most patients with neovascular age-related macular degeneration treated with bevacizumab achieved visual improvement over the course of 30 months without untoward side effects, according to a study presented here at the 2010 Annual Meeting of the Association for Research in Vision Ophthalmology (ARVO).
"This study suggests that a 30-month as-needed therapy with bevacizumab for choroidal neovascularisation in age-related macular degeneration is safe," said Renan Ferreira Oliveira, MD, Pontifícia Universidade Católica do Paraná, Curitiba, Brazil, on May 2.
For this noncomparative, retrospective study, researchers used a consecutive case series of 20 eyes from 16 patients with choroidal neovascularisation caused by age-related macular degeneration who were treated with at least 1 intravitreal injection of bevacizumab and completed a minimum follow-up of 30 months. Patients were excluded from the analysis if they had received prior verteporfin photodynamic therapy, photocoagulation, and intravitreal or periocular injections of triamcinolone, or other antiangiogenic drugs.
Patients who received bevacizumab 1.50 mg were analysed and then examined every 30 to 90 days. Additional treatments were given if the condition worsened after originally showing a positive functional response.
Patients enrolled in this study had a mean age of 75 years (range 59-87); 62.5% were women. They received 1 to 12 injections, but the average patient was injected 5 times.
"After 30 months from the beginning of therapy, best-corrected visual acuity declined in 8 eyes [40%], improved in 7 eyes [35%], and stabilised in 5 eyes [25%]," reported Dr. Oliveira.
No significant ocular or systemic side effects occurred.
"The functional results show that 60% of patients had improved or stabilised visual acuity," said Dr. Oliveira. "However, a large proportion of patients had a vision loss in spite of close ophthalmologic control and multiple intravitreal injections of bevacizumab."

Tips To Improve Your Vision – Get Rid Of Your Glasses!
Eyesight improvement is achievable. You can learn to see without glasses and be relieved permanently of the pain and distress so frequently associated with defective sight. But you cannot Improve your vision by magic.
CENTRAL FIXATION
The retina is a sensitive film on which the picture falls. But there is one point on the retina where the vision is perfect; that is the Macula Lutae, a point only one-sixteenth of an inch in diameter in the very center of the retina. When we focus at this point we have what is known as central fixation and our vision is perfect.
If you have lost the capacity of central fixation you are seeing with Eccentric fixation which often causes headaches, fatigue, pain or discomfort of some kind, such as twitching of the eyelids or the eyeballs. This twitching, by the way, can be stopped by pressing the sides of the base of the nose as high as the inner canthus with the forefingers of both hands, avoiding any pressure on the eyeballs.
Continue the pressure for several minutes, with the eyes closed, and you will obtain relief.
One way of checking on whether you are seeing by central or eccentric fixation is to look at a word on this page. Do you see it most sharply where you are looking or do you see it better when you look a little away from it? When you look at the top of a printed letter do you see the bottom of the letter more clearly than the top? If so, you have lost central fixation.
If you are to see, you must bring your mind to bear on what you see. Because the eye can focus sharply and is at its maximum power only on a very small area at a time, an attempt to see a larger area results in a blurring of physical vision and a lack of mental focus. Teach yourself to look at what you see, to watch one tiny area at a time. For when the central fixation is perfect, the eye sees perfectly.
THINK ABOUT WHAT YOU SEE
For significant eye sight improvement, give the object you are looking at your mental as well as your visual attention. The more clearly it registers on your mind, the more clearly it will register on the eye.
Test this out for yourself. In the room where you are sitting there are probably a dozen objects which you no longer “see” because you are so accustomed to their presence that you are no longer aware of them. Look at each one in turn, not staring, but with quick, easy glances, thinking about what you are regarding. That doorknob-could you have described it before? Now you know its approximate size, contour, the material of which it is made, its relative position on the door, because your mind and not alone your eyes observed it.
Even such a familiar phenomenon as a moving picture gives us what we believe we see rather than what we actually see. A series of still pictures provides us with an illusion of movement.
SEE A SMALL AREA AT A TIME
Instead of staring, trying to take in a whole picture at one time and thus defeating the object of central fixation, look at one small part of the picture, shift your gaze to another small part, and another, blinking naturally all the time. The smaller the area, the more clearly you will see it.
People who have acquired bad seeing habits always try to increase their area of vision by staring, which defeats its own purpose. Staring not only causes muscular tension but a lowering of vision. You can test this for yourself by staring fixedly at an object or a word on this page. After a few moments of this effort the letters lose their sharp clarity and become blurred.
Eyesight improvement can be achieved with consistent time, effort and proper eye health care!
