HTRA1 gene linked to aggressive 'wet' age-related macular degeneration
A gene variant that increases the risk of developing the aggressive "wet" form of age-related macular degeneration (AMD), the most common cause of blindness in people over age 50, is reported in two recent articles in Science by researchers at Yale School of Medicine.

Yellow plant pigments lutein and zeaxanthin reduce risk of age-related macular degeneration
Women younger than age 75 years who eat diets rich in the yellow plant pigments lutein and zeaxanthin may have a reduced risk of developing the eye disease age-related macular degeneration, according to a report in the August issue of Archives of Ophthalmology, one of the JAMA/Archives journals. Age-related macular degeneration (AMD) occurs when the macula, the area at the back of the retina that produces the sharpest vision, deteriorates over time. The condition is the leading cause of blindness in aging Americans, according to background information in the article. There is no cure for AMD and limited treatment options are available to slow its progression, so research on preventive measures is essential. Previous studies have suggested a potential link between AMD and lutein and zeaxanthin, plant pigments known as carotenoids and found in leafy green vegetables, corn, egg yolks, squash, broccoli and peas. These compounds may reduce the risk of AMD by absorbing blue light that could damage the macula, by preventing free radicals from damaging eye cells and by strengthening eye cell membranes.

In a study, Brian Chua, B.Sc., M.B.B.S., M.P.H., Westmead Millennium Institute and Vision Co-operative Research Centre, Syndney, Australia, and colleagues examined the association between dietary fat intake and AMD risk in 2,895 Australians age 49 years or older, beginning in 1992-1994. At the beginning of the study and again five years later, participants had a comprehensive eye exam that included photographs of the retina. They also filled out a questionnaire with data about food types and portion sizes consumed, including specific information about margarines, butters, oils and supplements.

High Body Mass Index Increase the Genetic Risk of AMD
Current cigarette smoking was associated with a fivefold increased risk and high BMI (30 or higher) was associated with a twofold higher risk of AMD. The homozygous risk genotype (CC) plus smoking conferred a tenfold higher risk of AMD, compared with non-smokers with the non-risk (TT) genotype, while the risk genotype plus higher BMI increased risk of AMD almost sixfold. Gene plus environment risk scores provided an area under the receiver operating characteristic (ROC) curve of 0.70-0.75. The attributable risks for the combination of genes and environment were 69% to 73%.

New genetic discovery explains 74 percent cases of age-related macular degeneration
A new study, led by researchers at Columbia University Medical Center, pinpoints the role that two genes Factor H and Factor B play in the development of nearly three out of four cases of age-related macular degeneration (AMD), a devastating eye disease that affects more than 10 million people in the United States. Findings indicate that 74 percent of AMD patients carry certain variants in one or both genes that significantly increase their risk of this disease.

Antioxidants reduce risk of age-related macular degeneration
A diet with a high intake of beta carotene, vitamins C and E, and zinc is associated with a substantially reduced risk of age-related macular degeneration in elderly persons, according to a study in the December 28 issue of JAMA. Age-related macular degeneration (AMD) is a degenerative disorder of the macula, the central part of the retina, and is the most common cause of irreversible blindness in developed countries, according to background information in the article. Late-stage AMD results in an inability to read, recognize faces, drive, or move freely. The prevalence of late AMD steeply increases with age, affecting 11.5 percent of white persons older than 80 years. In the absence of effective treatment for AMD, the number of patients severely disabled by late-stage AMD is expected to increase in the next 20 years by more than 50 percent to 3 million in the United States alone. Epidemiological studies evaluating both dietary intake and serum levels of antioxidant vitamins and AMD have provided conflicting results. One study (called AREDS) showed that supplements containing 5 to 13 times the recommended daily allowance of beta carotene, vitamins C and E, and zinc given to participants with early or single eye late AMD resulted in a 25 percent reduction in the 5-year progression to late AMD.
