Age Related Macular Degneration [AMD]
Nutritional supplement reduces risk of advanced AMD
The Age-Related Eye Disease Study (AREDS) — a landmark investigation conducted by the National Eye Institute (NEI) — determined that antioxidant supplementation can slow the progression of AMD. The AREDS formulation is an over-the- counter antioxidant supplement recommended for people who are at risk of developing advanced forms of either dry or wet AMD. The formulation includes the antioxidants beta carotene, vitamin E, and vitamin C, as well as the nutrients zinc and copper.
The NEI recently completed a second AREDS study (AREDS2) to evaluate the potential benefits of the antioxidants lutein and zeaxanthin and the omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). The results of AREDS2 showed that DHA and EPA did not confer additional benefit in reducing AMD risk. The researchers from AREDS2 did recommend that beta carotene in the original formula be replaced with lutein, because beta carotene can increase lung cancer risk in current and former smokers.

A new analysis of data from the National Eye Institute’s (NEI) Age-Related Eye Disease Studies (AREDS and AREDS2) has shown that the AREDS nutritional supplements slowed the progression of geographic atrophy (GA), the late-stage of dry age-related macular degeneration (AMD). For the majority in AREDS and AREDS2 who developed GA far from the fovea, the supplements slowed the rate of GA expansion towards the fovea by approximately 55 percent over an average of three years.
