Description of Collaborative Activity: |
AREDS2 is a multi-center randomized trial designed to assess the effects of oral supplementation of high doses of macular xanthophylls (lutein and zeaxanthin) and/or omega-3 LCPUFAs (DHA and EPA) for the treatment of AMD and cataract. The primary objective of AREDS2 is to evaluate the effect of dietary xanthophylls (lutein/zeaxanthin) and/or omega-3 LCPUFAs (DHA and EPA) on progression to advanced AMD. This objective will be accomplished by collecting and assessing the data on approximately 4,000 AREDS2 participants aged 50 to 85 years, who at the time of enrollment have either: 1) bilateral large drusen or 2) large drusen in one eye and advanced AMD (neovascular AMD or central geographic atrophy) in the fellow eye. |
