OBJECTIVE: To report the outcomes of micropulse cyclophotocoagulation in a Latin American population with refractory glaucoma in a "real-world" setting and to evaluate the factors associated with success after a one-year follow-up. MATERIALS AND METHODS: Retrospective, multicenter study. The medical records of patients who underwent micropulse cyclophotocoagulation between September 2017 and October 2018 were reviewed. Treatment success was defined as an intraocular pressure of 5 to 21 mmHg or a 20% intraocular pressure reduction with or without additional glaucoma medical therapy. RESULTS: Eighty-three eyes from 83 patients were included, with a mean follow-up of 10.1 ± 3.1 months. The intraocular pressure and number of glaucoma medications significantly decreased at all postoperative visits from a mean of 21.9 ± 7.6 mmHg on 3.8 medications to 13.1 ± 3.5 mmHg on 2.8 medications at the 12-month follow-up. The mean intraocular pressure decreased 40.1% from baseline at 12 months. The cumulative success rate was 54.5% (95% CI, 44-67%) at 12-month follow-up. We identified a higher baseline intraocular pressure as a significant independent predictor of treatment success (p = 0.03). Late complications included 1 eye with corneal edema, 1 eye with prolonged anterior chamber inflammation and cystoid macular edema and 9 eyes (11%) with visual loss of 2 Snellen lines or more. CONCLUSIONS: Micropulse cyclophotocoagulation is an effective and safe treatment for Latin American patients and can provide intraocular pressure and medication reductions with a single treatment after a one-year follow-up. A high baseline intraocular pressure was the most significant predictor of treatment success.
