[Antioxidants and angiogenetic factor associated with age-related macular degeneration (exudative type)]

To confirm the hypothesis that antioxidants and angiogenetic factors may be associated with the development of age-related macular degeneration (exudative type), we compared serum levels of vitamins A, C, and E and carotinoid, zinc, selenium and b-FGF (basic-fibroblast growth factor) in 35 patients with age-related macular degeneration (exudative type) with the levels in 66 controls. The average serum zinc level was significantly lower in the patient group than in the control group. Serum vitamin E-alpha levels also tended to be lower. Most serum b-FGF levels were below the standard value in each group. Based on the above results, we conclude that subnormal levels of zinc and vitamin E may be associated with the development of age-related macular degeneration.
