Merits of trabeculectomy in advanced and end-stage glaucoma.

OBJECTIVES: The aim of the study was to evaluate intraocular pressure (IOP) control, potential benefits, and associated complications in advanced cases of glaucoma (visual acuity of <6/60) after trabeculectomy. Although many studies of trabeculectomy in glaucoma patients have been done, very few in such advanced cases. METHODS: The study was done on 60 cases of advanced primary open-angle glaucoma (POAG). Trabeculectomy was done and IOP control was assessed. Pre-operative workup included a detailed history, slit lamp biomicroscopy, Goldmann applanation tonometry, gonioscopy using Goldmann 2 mirror lens, and detailed fundus examination with the 78D lens. All the patients were to undergo optical coherence tomography and Humphrey automated perimetry. RESULTS: < 0.000). CONCLUSION: Trabeculectomy is a successful method of controlling IOP in patients with advanced glaucoma. Trabeculectomy is the method of reducing IOP in medically uncontrolled patients. A pain-free eye was associated with better quality of life in patients. A successful trabeculectomy helps to preserve the residual vision in such patients.
