title: Indocyanine green videoangiography of idiopathic polypoidal choroidal vasculopathy.
abstract: OBJECTIVE
  To identify the precise choroidal abnormalities associated with idiopathic polypoidal choroidal vasculopathy (IPCV), patients with IPCV were examined with indocyanine green (ICG) videoangiography.
  
  
  METHODS
  Twelve patients with IPCV were examined using standard clinical, fluorescein, and ICG videoangiographic techniques.
  
  
  RESULTS
  Indocyanine green videoangiography showed two basic choroidal vascular changes: a branching network of vessels in the inner choroid, and vascular dilations at the border of the network of vessels. The vascular dilations appeared to be associated with the exudative and hemorrhagic manifestations of IPCV.
  
  
  CONCLUSIONS
  The choroidal vasculopathy seen in IPCV is distinct from the changes seen in other choroidal abnormalities. Recognition of these changes aids in diagnosis and patient management, since the clinical implications of IPCV differ from those of other similar entities.
