title: [Experimental choroidal neovascularization induced by laser in the eyes of rhesus monkeys].
abstract: OBJECTIVE
  To establish an experimental model of choroidal neovascularization (CNV) through perimacular laser treatment in the eyes of rhesus Monkey.
  
  
  METHODS
  The experimental CNV was induced by perimacular laser injury in the eyes of 8 rhesus monkeys and confirmed by a comparison before and after the laser treatment (20 d, 34 d, 48 d) with fluorescence fundus angiography (FFA) and optical coherence tomography (OCT).
  
  
  RESULTS
  Classic CNV similar to human CNV appeared in 68.8% of the laser spots. Hypofluorescence in the early phase and fluorescence leakage in the late phase were detected by the FFA. High reflect light echogenic mass and retina edema were detected by the OCT. The histopathologic examinations found proliferated fiber-vasculosa membranes in the laser burnt spots. The pathological changes lasted 48 days until the monkeys were killed.
  
  
  CONCLUSIONS
  The laser induced experimental CNV in rhesus monkey has a high prevalence and stability, which maintains a long period. It is an ideal experimental model for studying the pathologic mechanism of CNV and effective treatment for CNV.
