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).
