[Distribution and morphology of peripheral anterior synechia in primary angle-closure glaucoma]

Abstract

We examined 91 patients (151 eyes) with primary angle-closure glaucoma (PACG) by pressure gonioscopy and studied the distribution and the morphology of peripheral anterior synechia (PAS). The incidence of the PAS were 85:7% in acute PACG, 47.1% in their fellow eyes and 86.6% in chronic PACG. The PAS in acute PACG were wider and taller than that of chronic PACG. The wide PAS were most common in the superior quadrant, and were more prevalent than the narrow PAS. The PAS as a whole was more frequently seen in the superior. The wide PAS was taller than the narrow PAS. The PAS indices showed no significant correlation with age but with duration of acute attack.
