Inverse association of female hormone replacement therapy with age-related macular degeneration and interactions with ARMS2 polymorphisms.

ABSTRACT: Purpose. To investigate whether female reproductive history and hormone replacement therapy (HRT) or birth control pills (BCPs) influence risk for age-related macular degeneration (AMD) and whether genetic factors interact with HRT to modulate AMD risk. Methods. Related and unrelated female participants (n = 799) were examined and data were analyzed with generalized estimating equations with adjustment for age and smoking. Individuals with AMD grades 1 to 2 were considered to be unaffected (n = 239) and those with grades 3 to 5 were considered affected (n = 560). Results. When comparing all cases with controls, significant inverse associations were observed for HRT (odds ratio [OR] = 0.65, 95% CI 0.48-0.90, P = 0.008) and BCPs (OR = 0.60, 95% CI 0.36-0.10, P = 0.048). When analyses were st
