Outcome of Trabeculectomy in Sokoto
Glaucoma
Abstract
Introduction: Glaucoma is the second leading cause of blindness worldwide1 and the leading cause of irreversible blindness accounting for 6.6% of 39 million global burden of blindness2 . Trabeculectomy is said to be better than both medical and laser therapies in IOP control especially among Africans where compliance and availability of drugs are limited3-5. The aim of this study was to assess the outcome of trabeculectomy in patients diagnosed with glaucoma between May 2008 and December 2015 in Usmanu Danfodiyo University Teaching Hospital, Sokoto and Specialist Hospital, Sokoto.
Methods: This was a retrospective case series. The medical records of all glaucoma patients who had trabeculectomy between May 2008 and December 2015 in the two facilities were reviewed. Demographic and clinical data were retrieved. All glaucoma patients aged 9 years and above who had trabeculectomy or combined glaucomacataract surgery were eligible for inclusion in the study. Ethical approval was obtained from the Ethics and Research Committee of the Usmanu Danfodiyo University Teaching Hospital, Sokoto. All patients had a Cairns-type trabeculectomy. 6 Some surgeries were performed with the use of antimetabolites- Mitomycin C (MMC) or 5 Fluorouracil (5FU) based on availability of the antimetabolites at the time of surgery. Two surgeons performed all the surgeries. The primary outcome measure was percent IOP reduction from baseline during the post-operative period. Data was analysed using Stata 14 statistical software.
