Abstract

Purpose:  To determine the outcomes of trabeculectomy in patients with open angle glaucoma at a newly established glaucoma clinic in a tertiary care hospital of Khyber Pakhtunkhwa.

Study Design:  Retrospective chart review.

Place and Duration of Study:  Glaucoma Clinic, Hayatabad Medical Complex, Peshawar from May 2018 to December 2019.

Methods:  A retrospective chart review of patients of 18 years age or above and who underwent trabeculectomy for open angle glaucoma, with at least one follow-up visit were included. Data was collected for age, gender, type of glaucoma, preoperative best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of pre-operative/post-operative topical anti-glaucoma medications, indication for trabeculectomy, preoperative comorbidities and postoperative complications. Data were analyzed using SPSS version 23. The student’s paired t-test was used for comparative analysis of the same group. A p-value of < 0.05 was considered significant.

Results:  A total of 20 eyes of 20 patients were included in this study, 13 (65%) patients were males, and the mean age was 54.60 ± 18.22 years. There was a statistically significant change in mean IOP postoperatively (35.60 ± 13.28 versus 11.2 ± 6.1, P < 0.001) and number of antiglaucoma medication (2.95 ± 1.19 versus 0.4 ± 0.99, P < 0.001). While there was no significant change in best-corrected visual acuity (1.35 ± 0.88 versus 1.06 ± 0.72, p = 0.36).

Conclusion:  Trabeculectomy performed at the newly established glaucoma clinic showed a significant reduction in Intraocular pressure without compromising the visual acuity of the study participants.
