Abstract

Treatment modalities for open/closed angle glaucoma’s differ considerably and gonioscopy is the most valuable and simple tool for classifying angle/glaucoma. This study aimed at finding variations in anatomy of angle of anterior chamber in various types of glaucoma patients. This prospective study was done from June 2011 to May2013. Gonioscopic examination of 100 glaucoma patients was done by Goldman 3-mirror goniolens by single examiner and findings were noted down using Shaffer’s grading. Out of 100, 37 were bilateral and 63 uniocular glaucoma patients, 54 were males and 46 were females. 51 patients had POAG and 39 patients had PACG and 10 patients had occludable angle. 15 patients were already operated. PAS were found in 17 patients. Pigmentation was found in 34 patients. Iris processes were found in 19 patients. Foreign body in the angle and blood in schlems-canal was found in 1 patient each. Out of the 15 operated patients, 11patients had patent scleral window. 4 patients had obliterated scleral window (all PACG) and 7 patients showed highly pigmented angle. Along with categorizing patients into open/closed angle glaucoma, gonioscopy also helps in deciding management, following-up post-operative cases and to decide whether any re-procedure is required.
