Long-term evaluation of trabeculectomy in primary open angle glaucoma and chronic primary angle closure glaucoma in an Asian population.

摘要

Purpose: A retrospective cohort study was undertaken to evaluate and compare the long-term results of trabeculectomy in primary open angle glaucoma (POAG) and chronic primary angle closure glaucoma (CPACG) in an Asian population. Methods: Yearly diurnal measurements of intraocular pressure (IOP), best-corrected visual acuity, optic disc and visual field records of patients having primary adult glaucomas who had undergone trabeculectomy, without anti-mitotic agents, with a minimum of 5 years follow up were evaluated. Only one eye of each patient was studied. The success rates for IOP control in POAG and CPACG were statistically analysed. Results: Sixty-four eyes of 64 patients were studied. The overall probability of success of trabeculectomy in controlling IOP to
