PURPOSE: 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).
CONCLUSION: PPCA has strong correlation with MD, the progress of P3 area was an important parameter to identify glaucoma.
