Background: Age-related macular degeneration is the most common cause of irreversible central visual loss in individuals over 50 years old. The aim of this study was to assess visual loss due to age-related macular degeneration and some of its associated risk factors. Materials and Methods: This case-control study was conducted on 150 patients with age-related macular degeneration and 150 controls, both aged over 50. A questionnaire on demographic and medical information was completed for each participant and an ophthalmological examination was performed. The results were recorded andthe data were analyzed using SPSS software version 16. Results: Mean age of the subjects in the case and control groups was 78.38 and 79.28 years, respectively.In a multivariable model, hypertension(p=0.003), diabetes(p=0.006), light iris color(p=0.05), hypercholesterolemia (p=0.036), lens opacity (p=0.029), and previous cataract surgery(p=0.029) were significantly associated with age-related macular degeneration. There was not a significant relationship between body mass index (p=0.11) and refractory errors (p=0.94) andage-related macular degeneration. Conclusion: Age-related macular degeneration is associated with hypertension, diabetes, hypercholesterolemia, light iris color, lens opacity, and previous cataract surgery.
