title: [The relationship between peripapillary choroidal atrophy and visual field defects in open angle glaucoma].
abstract: OBJECTIVE
  To study the relationship between peripapillary choroidal atrophy (PPCA) and mean defect (MD) in visual field in primary open angle glaucoma (POAG) and suspected open angle glaucoma (SOAG).
  
  
  METHODS
  One hundred and twenty-eight eyes with POAG and 78 eyes with suspected open angle glaucoma were examined with Oculus Twinfield static threshold perimetry test (program 24-2) and monocular disc color photographs.
  
  
  RESULTS
  In POAG group, the incidence rate of alpha-area and beta-area were 57.03% and 39.84%, respectively. The average area of alpha-zone and beta-zone were (0.54 +/- 0.37) mm2 and (1.68 +/- 1.06) mm2. The mean defect is (8.31 +/- 3.66)dB. In suspected open angle glaucoma, they were 43.59% and 26.92%, (0.42 +/- 0.29) mm2 and (1.15 +/- 0.67) mm2, and (4.16 +/- 2.07)dB, respectively. The area of alpha and beta has strongly positive correlation with MD in two groups (P < 0.001).
  
  
  CONCLUSIONS
  PPCA has strong correlation with MD, the progress of P3 area was an important parameter to identify glaucoma.
