Purpose: The purposes of this study were to determine the rate of adherence to the recommendations of the Age-Related Eye Disease Study (AREDS) regarding vitamin supplement use among patients with age-related macular degeneration (AMD) at a tertiary retina center and to identify factors associated with adherence. Methods: Consecutive patients with a history of AMD were administered an in-person survey designed to assess use of vitamin supplementation as well as to investigate factors that may influence supplementation use patterns. A retina specialist performed dilated funduscopic examinations and categorized patients' AMD severity according to the AREDS classification system. The main outcome measure was rate of adherence to AREDS recommendations. Results: Sixty-four patients with AMD completed the survey. Sixty-three percent of patients met AREDS criteria for vitamin supplementation. Of those patients who met the criteria, only 43% reported taking AREDS vitamins in the recommended dosages. Among patients using AREDS vitamins as recommended, 100% were return patients to the tertiary retina center and reported a retina specialist as the primary recommendation source for supplement use. Of patients who met AREDS criteria for vitamin supplementation but were not taking vitamins as per AREDS recommendations, 87% were new patients to the retina service and 75% reported that vitamin supplementation had never been recommended to them. Conclusion: Patients with intermediate or advanced AMD in at least one eye show a low adherence rate to the AREDS recommendations for vitamin supplementation.
