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.
