    Resveratrol — found in red wine, grapes, blueberries, peanuts and other plants — stops out-of-control blood vessel growth in the eye, according to vision researchers at Washington University School of Medicine in St. Louis. The discovery has implications for preserving vision in blinding eye diseases such as diabetic retinopathy and age-related macular degeneration, the leading cause of blindness in Americans over 50. The formation of new blood vessels, called angiogenesis, also plays a key role in certain cancers and in atherosclerosis. Conducting experiments in mouse retinas, the researchers found that resveratrol can inhibit angiogenesis. Another surprise was the pathway through...

    BOSTON (June 18, 2009) - Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken, report researchers at the Laboratory for Nutrition and Vision Research (LNVR), Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University. The researchers calculated intakes of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) from dietary questionnaires administered to 2,924 men and women, aged 55 to 80 years, participating in an eight-year supplement trial, the...

    A combination of vitamin B-6, vitamin B-12 and folic acid might protect women against age-related macular degeneration, the leading cause of blindness in the elderly, a new study finds. Women taking this trio of vitamins in amounts well beyond the recommended daily doses were one-third less likely to develop macular degeneration than were people taking placebos, researchers report in the Feb. 23 Archives of Internal Medicine. Cigarette smoking is known to increase a person’s likelihood of developing macular degeneration. Other than not smoking, there is little a person can do to limit risk, says study coauthor William Christen, an epidemiologist...
  • Hurler regains sight after 'miracle' diet supplement (macular degeneration)

    Former Cork club hurler Jimmy Aherne wept when he was told he would be blind within three years. The father-of-four -- who is a second cousin to hurling legend Christy Ring -- was diagnosed with age-related macular degeneration (AMD). The condition is cruel, as it has traditionally been untreatable. For decades, thousands of pensioners who lost their sight were simply told they had "old people's blindness" and that nothing could be done for them. But today, almost 12 months after that shocking diagnosis, the deterioration in Jimmy's eyesight has been halted and his good eye has improved to the point...

    The ability of zebrafish to regenerate damaged retinas has given scientists a clue about restoring human vision and could lead to an experimental treatment for blindness within five years. British researchers said on Wednesday they had successfully grown in the laboratory a type of adult stem cell found in the eyes of both fish and mammals that develops into neurons in the retina. In future, these cells could be injected into the eye as a treatment for diseases such as macular degeneration, glaucoma and diabetes-related blindness, according to Astrid Limb of University College London's (UCL) Institute of Ophthalmology.

    Certain kinds of carbohydrates may play a role in the development of age-related macular degeneration, an incurable degenerative eye disease that is a leading cause of blindness in older adults. A new study has found that eating carbohydrate-rich food with a high glycemic index — a measure of a food’s potential to raise blood glucose levels — is associated with the development of the disorder. The glycemic index is a measure of how fast carbohydrates are metabolized — the faster they are broken down into glucose, the higher the glycemic index. Simple carbohydrates, like those in cakes and cookies, cheese...

    LONDON - The Royal National Institute of the Blind (RNIB) has said that young people are unaware of the fact that smoking could lead to blindness. The charity says that if the government were to fund a national campaign, then young people could give up smoking. For evidence, it cites an article in the British Journal of Ophthalmology, which found that the fear of blindness was more of a deterrent than anything else. The study surveyed around 250 clubbers in Winchester, Manchester and Southampton. All responders were aged between 16 to 18 years. On a scale of 5, most rated...

    A bionic eye implant that could help restore the sight of millions of blind people could be available to patients within two years. US researchers have been given the go-ahead to implant the prototype device in 50 to 75 patients. The Argus II system uses a spectacle-mounted camera to feed visual information to electrodes in the eye. Patients who tested less-advanced versions of the retinal implant were able to see light, shapes and movement. "What we are trying to do is take real-time images from a camera and convert them into tiny electrical pulses that would jump-start the otherwise...

    A silicon chip that faithfully mimics the neural circuitry of a real retina could lead to better bionic eyes for those with vision loss, researchers claim. About 700,000 people in the developed world are diagnosed with age-related macular degeneration each year, and 1.5 million people worldwide suffer from a disease called retinitis pigmentosa. In both of these diseases, retinal cells, which convert light into nerve impulses at the back of the eye, gradually die. Most artificial retinas connect an external camera to an implant behind the eye via a computer (see 'Bionic' eye may help reverse blindness). The new silicon...

    Overweight and obese people should be aware that their unhealthy lifestyle could put their eyesight at risk, scientists say. It is common knowledge that expanding waistlines are linked to conditions such as diabetes, heart disease and cancer. But research shows that obesity is also linked to eye problems, which could lead to loss of eyesight. Two Israeli ophthalmologists are now warning that the prospect of eye disease should also be a powerful incentive to lose weight. Professor Michael Belkin and Dr Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Centre, reviewed more than 20 studies involving thousands...

    Marion Kleinfeld got up one Sunday morning, picked up the newspaper, settled down to read it, and couldn't see the words. Kleinfeld, 79, of Delray Beach, Fla., already blind in her right eye, lost sight in her other eye because of a condition called wet age-related macular degeneration, AMD, the leading cause of blindness in people over 55. Leaking blood vessels in the back of the eye cause a large black spot in the center of vision. "I could not see at all. It was very frightening," she said. After years of having to tell patients losing their eyesight to...

    MONDAY, July 10 (HealthDay News) -- In a study of male twins, researchers have found that those who smoke had an increased risk of developing age-related macular degeneration. In addition, the researchers found that men who ate more fish rich in omega-3 fatty acids -- such as mackerel, lake trout, sardines, albacore tuna and salmon -- had a lower risk of developing the vision-robbing disease. Age-related macular degeneration (AMD) is the leading cause of irreversible visual impairment and blindness in people aged 60 and older, and as the population ages the problem will affect more people. Moreover, there's no cure...

    ASSOCIATED PRESS WASHINGTON -- The first drug shown to significantly improve the vision of patients threatened by a major cause of blindness in the elderly won federal approval Friday. The drug, called Lucentis, treats the wet form of age-related macular degeneration, a disorder where blood vessels behind the retina leak blood and fluid, worsening vision and often causing blindness. An estimated 90 percent of the 1.4 million Americans who have lost their eyesight due to the disorder have the wet form. Lucentis, made by Genentech, Inc., a South San Francisco, Calif., biotechnology company, inhibits the growth of blood vessels when...

    UF finding could lead to approaches to treat macular degeneration GAINESVILLE, Fla. - University of Florida scientists conducting experiments with mice have found evidence that the body naturally replenishes small amounts of cells in the eye essential for healthy vision. The finding may shatter the belief that a cell layer vital for eyesight called the retinal pigment epithelium, or RPE, is a nonrenewable resource, say researchers writing in a recent issue of Investigative Ophthalmology & Visual Science. RPE plays a vital role in our visual health by forming the outer barrier of the retina and supporting the function of cells...

    Scientists say they have identified a genetic variation that substantially raises the risk of age-related macular degeneration, the leading cause of severe vision loss in the elderly. The finding, being reported independently by three separate research groups, sheds light on the cause of the disease and could provide clues to how to develop treatments or strategies to prevent the condition. The genetic variation "explains a lot of the risk," said Dr. Albert O. Edwards, an ophthalmology researcher in Dallas who led of one of the studies. "There's a primary biological explanation for A.M.D. now. It gives you some obvious avenues...

    Associated Press The Food and Drug Administration yesterday approved a new drug designed to treat the leading cause of blindness in older Americans. Age-related macular degeneration destroys the light-sensitive tissue in the center of the retina, causing vision to fail gradually from the center outward. The new drug, Macugen, attacks the rapidly progressing "wet" type of AMD, in which new blood vessels form behind the retina and then leak, damaging the macula. That form affects an estimated 1.6 million Americans over 50, and about 6.3 million are expected to be affected by 2030 as the baby boomers age. Macugen inhibits...
