In a study reported in the August 2008 issue of the American Journal of Clinical Nutrition, eating fish oil at least once a week is linked to a reduced risk for neovascular age-related macular degeneration (NV-AMD). In the European Eye Study, participants 65 years of age or older underwent fundus photography, with images graded by the International Classification System for Age Related Maculopathy. Dietary consumption data and fundus photographs were available for 105 case patients with NV-AMD and for 2170 control subjects without any evidence of early or late AMD. "Eating oily fish at least once per week compared with less than once per week was associated with a halving of the odds ratio for NV-AMD" the study authors write. *
A second study reported in the June 2008 issue of the Archives of Ophthalmology reported similar results. Nine studies included a total of 88,974 people, including 3203 cases of AMD. High dietary intake of omega-3 fatty acids was associated with a 38% reduction in the risk for AMD. Eating oily fish at least twice a week was associated with a decreased risk for both early AMD and late AMD. **
For those who don't enjoy eating oily fish, such as salmon, Pharmacy Innovations offers a wide variety of high quality Omega-3 fish oil supplements in both liquid and capsule form. The quality of these supplements varies greatly-let us help you find the highest quality, most economical product.

A new study, funded by the National Institutes of Health, has found that taking B vitamins can prevent age-related macular degeneration. AMD is the leading cause of blindness in people 65 and older, with nearly 2 million Americans in the advanced stage of the condition.
"Other than avoiding cigarette smoking, this is the first suggestion from a randomized trial of a possible way to reduce early stage AMD," said William Christen of Harvard-affiliated Brigham and Women's Hospital in Boston, who led the research. He said the findings should apply to men as well.*
The women in the study who took a combination of B vitamins- B-6, folic acid and B-12- reduced their risk by more than one-third after seven years compared to women taken placebos. The study, involved more than 5,000 women ages 40 and older. Allen Taylor, director of the Laboratory for Nutrition and Vision Research at Tufts University in Boston, said the study was "strong because patients were assigned at random and followed a long time."*
