title: Optical coherence tomographic findings of idiopathic polypoidal choroidal vasculopathy.
abstract: OBJECTIVE
  To identify the histological level of abnormal vessels associated with idiopathic polypoidal choroidal vasculopathy (IPCV), we examined IPCV with Optical Coherence Tomography (OCT).
  
  
  METHODS
  Fourteen patients diagnosed with IPCV were examined with Indocyanine green (ICG) angiography and OCT.
  
  
  RESULTS
  ICG angiography demonstrated branching vascular networks with polypoidal dilatations at the terminals beneath the retinal pigment epithelium (RPE). OCT showed dome-like elevation of the RPE, and moderate reflex or nodular appearance were seen beneath the RPE.
  
  
  CONCLUSIONS
  The abnormal vessel associated with IPCV is supposed to be choroidal neovascularization with polypoidal dilatations at the terminals between Bruch's membrane and RPE. We consider that this disease is a peculiar form of age-related macular degeneration.
