Background : Some cases of polypoidal choroidal vasculopathy (PCV) in their natural course develop into classic choroidal neovascularization (CNV) as shown by fluorescein angiography(FA) findings.Subjects and Method : We evaluated 8 eyes of 8 PCV patients showing classic CNV by FA findings, using indocyanine green angiography (IA) and optical coherence tomography (OCT).Result : All patients showed subretinal grayish exudates, which were considered fibrinous. Five cases were recognized as true subretinal CNV according to IA and OCT findings. The other 3 patients showed polypoidal dilatation with vascular networks by IA, and a moderately reflective mass considered fibrinous over the polypoidal elevation of retinal pigment epithelium(RPE) by OCT.Conclusion : Both true CNV and PCV with fibrin are present in PCV patients showing classic CNV. It requires care to determine proper treatment.
