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 α-area and β-area were 57.03% and 39.84%, respectively. The average area of α-zone and β-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 α and β has strongly positive correlation with MD in two groups (P < 0.001). CONCLUSION: PPCA has strong correlation with MD, the progress of β area was an important parameter to identify glaucoma. LA: Chinese
