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