From the USA: Micronutrient Supplementation Slows Geographic Atrophy Progression
Oral micronutrient supplementation slows geographic atrophy (GA) progression in age-related macular degeneration (AMD), according to a study published online July 16 in Ophthalmology.
Tiarnan D.L. Keenan, B.M., B.Ch., Ph.D., from the National Institutes of Health in Bethesda, Maryland, and colleagues examined whether oral supplements slow GA progression in AMD in a post-hoc analysis of the Age-Related Eye Diseases Study (AREDS) and AREDS2 multicenter, randomized trials. A total of 392 eyes from 318 participants with GA were included in AREDS, and 1,210 eyes from 891 participants with GA were included in AREDS2. AREDS participants were randomly allocated to oral antioxidants; zinc (80 mg); combination; or placebo. AREDS2 participants were randomly assigned to lutein/zeaxanthin; docosahexaenoic acid/eicosapentaenoic acid; combination; or placebo. AREDS2 participants were also randomly assigned to alternative AREDS formulations: original, no β-carotene, zinc (25 mg), or both.
