Age-related macular degeneration (ARMD) ts the leading cause of blindness among the elderly in the United States. This study is an effort to develop a cost-effective testing protocol that can be used by eye care clinicians to identify who is likely to develop ARMD so that these individuals can receive preventive care. This study is part of a nationwide, multi-center, double-masked project on the effectiveness of antioxidant vitamin/mineral supplementation to treat ARMD. Five testing procedures used to diagnose ARMD were evaluated: foveal red threshold automated perimetry, contrast sensitivity, Amsler grid, nutritional intake data analysis, and blood chemistry analysis. The results indicate that normal subjects and those with ARMD have different results when tested using these procedures. When these tests are used in combination, they provide a strong protocol for identifying individuals who are likely to develop ARMD.
