title: [The study of the classification on polypoidal choroidal vasculopathy].
abstract: OBJECTIVE
  To establish and explore the criteria of the classification on polypoidal choroidal vasculopathy (PCV).
  
  
  METHODS
  The 42 patients (48 eyes) with PCV were classified according to the location, staining or not in late indocyanine green angiography (ICGA), with or without branching vascular network, and the extent of hemorrhagic or exudative.
  
  
  RESULTS
  According to the location, staining or not in late ICGA, with or without branching vascular network, and the extent of hemorrhagic or exudative, the PCV were classified as macular (30 eyes, 62.5%), arcade (6 eyes, 12.5%), peripapillary (3 eyes, 6.3%), midperiphery and Combination PCV (9 eyes, 18.8%); active (34 eyes, 70.8%) and inactive PCV (14 eyes, 19.2%); typical (36 eyes, 75.0%) and atypical PCV (12 eyes, 25.0%); hemorrhagic (35 eyes, 72.9%) and exudative PCV (13 eyes, 27.1%), respectively. The classification on location of the polypoidal lesions and with or without branching vascular network of the lesions were the first suggested.
  
  
  CONCLUSIONS
  The classification of PCV is beneficial for describing the clinical manifestations and for predicting the prognosis and for guiding the treatment of the disease.
