Investigation of precursor lesions of polypoidal choroidal vasculopathy using contralateral eye findings

The purpose was to investigate precursor lesions of polypoidal choroidal vasculopathy (PCV). This cross-sectional study involved 276 unaffected contralateral eyes from unilateral PCV patients (Group 1), unilateral typical exudative age-related macular degeneration (AMD) patients (Group 2), and unilateral epiretinal membrane patients (Group 3) as age-matched controls.
