Trabeculectomy Efficacy in a Latin American Ophthalmology Training Institution.

Abstract

Aim: To report trabeculectomy efficacy in a Latin American Ophthalmology Training Institution.

Materials and methods: Retrospective study between March 2015 and March 2019, Medical records of 77 patients (96 eyes) that underwent trabeculectomy were reviewed. Collected data included glaucoma type, pre- and post-trabeculectomy intraocular pressure (IOP) and glaucoma therapy and assigned surgeon. Data analysis included descriptive statistics, Paired T student double tailed, and Welch-Satterthwaite test.

Results: Ninety-six eyes (77 patients) that underwent trabeculectomy were included in the analysis. 44.79% were male and 55.20% female. Median age was 54.04 ± 18.92 years. Median IOP pretrabeculectomy was 27.86 ± 10 mm Hg. More commonly found diagnoses were narrow angle glaucoma (36.46%), primary open-angle glaucoma (18.75%), and secondary to chronic steroid use glaucoma (14.58%). Median IOP reduction from basal IOP at 6 weeks, 6 months, and 12 months after trabeculectomy was 15.87 mm Hg, 14.42 mm Hg and 14.55 mm Hg, respectively, p < 0.05. Cumulative success was 66.66% at 12 months follow-up. General decrease of antiglaucomatous topical therapy was 1.9 ± 1.09 (p > 0.05) eye drops. Trabeculectomy success rate was 69.23% for attendants and 65.71% for residents (p = 0.85).

Conclusion: Trabeculectomy continues to be a successful and effective therapy to obtain significant and stable IOP decrease. Success trabeculectomy rates are comparable between residents and attendants.
