Abstract: Purpose Polypoidal choroidal vasculopathy (PCV) has been described as a distinct clinical entity from choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). The present study aimed to determine risk factors for PCV and to compare associations with those for CNV secondary to AMD. Design Case-control study. Participants Patients of Chinese ethnicity with clinically and angiographically diagnosed PCV (n = 123) or CNV secondary to AMD (n = 128) were recruited from a tertiary eye hospital in Singapore. Controls without signs of PCV, CNV secondary to AMD, or other retinal pathologic features (n = 1489) were selected from a population-based study. Methods Patients underwent an ophthalmologic examination including digital color fundus photography, stereoscopic fluorescein angiography (FA), and indocyanine green angiography (ICGA). Classification into PCV or CNV secondary to AMD was based on FA and ICGA findings. Risk factors were determined from a standardized interview, with blood pressure recorded using a digital automatic blood pressure monitor. Main Outcome Measures Polypoidal choroidal vasculopathy or CNV secondary to AMD. Results Persons who smoked were more likely to have PCV (39.9% vs. 13.4%) or CNV secondary to AMD (45.0% vs. 12.3%) than those who did not smoke. After controlling for age, gender, diabetes, hypercholesterolemia, and hypertension, persons who smoked were 4 times more likely to have PCV (odds ratio [OR], 4.4; 95% confidence interval [CI], 2.57.7; P
