Study Summary
Objective: The objective of this study was to determine whether the antioxidant supplements used in AREDS shifted the plasma pool of the AREDS subjects to a more reduced state. The AREDS subjects were randomly assigned to one of four treatment groups: 1. antioxidants (500mg Vitamin C, 4000IU Vitamin E, 15mg beta carotene) 2. zinc (80mg zinc oxide, 2mg cupric oxide) 3. antioxidants plus zinc; 4. placebo. None of the subjects received supplemental GSH or cyst (e) ine. Age-related macular degeneration (AMD) is the leading cause of severe visual impairment in elderly Americans, with an estimated 15 million people having some form of this disease. AMD primarily affects the central vision and many patients develop severe visual handicaps. Currently there are no clear established understandings of the etiology or pathogenesis of this disease.
