Trabeculectomy Efficacy in a Latin American Ophthalmology Training Institution

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

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.

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).

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.
