To compare the association of systemic risk factors between neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV).Seven hundred and three patients (235 with nAMD and 468 with PCV) were included. Associated systemic conditions, including hypertension, cardiovascular disease, stroke, diabetes mellitus, and end-stage renal disease, were investigated through an interview and questionnaire.The prevalence of diabetes mellitus and end-stage renal disease in nAMD was significantly higher than that in PCV (P < 0.001 and P = 0.021, respectively, multivariate logistic regression analysis). Moreover, in diabetic patients with nAMD or PCV, the more severe form of diabetic retinopathy was more prevalent in nAMD cases than in PCV cases (P = 0.006, multivariate logistic regression analysis).Diabetes mellitus and end-stage renal disease are more prevalent in patients with nAMD than in those with PCV. Specific systemic conditions might be associated with the development of nAMD.
