Abstract

To determine the frequency of peripapillary atrophy (zone beta)and the relationship between peripapillary atrophy and glaucomatous optic nerve damage in eyes with primary angle-closure glaucoma, we performed magnification-corrected morphometry of photographs of 88 eyes of 64 patients with primary angle-closure glaucoma. Forty-nine (56%)of 88 eyes with primary angle-closure glaucoma had zone beta. The zone beta/disc area ratio increased significantly (P=0.0001)with a decreasingrim/disc area ratio (r=-0.49).Moreover, the area, angular extent, width, and the frequency of zone betaincreased significantly with increasing stage of glaucoma (P<0.005).In contrast, there was no significant correlation between the zone beta/disc area ratio and perimetric results.We found that zone betawas present in more than half and it is closely associated with glaucomatous optic nerve damage in primary angle-closure glaucoma.
