[Evaluation of cases of polypoidal choroidal vasculopathy showing classic choroidal neovascularization in their natural course].
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.


METHODS
We evaluated 8 eyes of 8 PCV patients showing classic CNV by FA findings, using indocyanine green angiography (IA) and optical coherence tomography(OCT).


RESULTS
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.


CONCLUSIONS
Both true CNV and PCV with fibrin are present in PCV patients showing classic CNV. It requires care to determine proper treatment.
