Abstract

Polypoidal choroidal vasculopathy (PCV) is a form of neovascular AMD characterized by polypoidal lesions and branching vascular networks. Diagnosis has traditionally required the use of invasive indocyanine green angiography, though recently a validated non-invasive diagnostic system has been developed that identified PCV-specific features using optical coherence tomography (OCT) and color fundus photography. In this work we applied this new system to a large population-based cohort of ethnic Chinese and successfully identified PCV and related anatomical features. We estimated a population prevalence of 0.31% (95% CI, 0.06-0.91%) and additionally demonstrate that PCV-related retinal findings were relatively rare in the population.
