Micropulse transscleral cyclophotocoagulation in glaucoma treatment. Preliminary results

Abstract

Objective. To evaluate the preliminary results after micropulse cyclophotocoagulation in patients with primary open-angle refractory glaucoma (POAG) and neovascular glaucoma. Methods. Retrospective study of adult patients with glaucoma, with at least 6 months follow-up after the only one session of micropulse laser therapy. The study included 16 patients, 17 eyes with refractory primary open-angle glaucoma (POAG) and neovascular glaucoma. Follow up period was 6 months. The same surgical technique was used in all cases. The wavelength of the laser beam was 810 nm, the total exposure was 160 s, the energy was 2000 mJ, 31,3% of active cycle, the pulse duration was 0.5 ms, the period was 1.1 ms. Results. The average decrease in IOP was 26.6%. No complications identified Conclusions: micropulse transscleral cyclophotocoagulation has been shown to be safe and effective in lowering IOP in patients with refractory glaucoma. However, further study of this method is required. Key words: micrоpulse transscleral cyclophotocoagulation, glaucoma, intraocular pressure.
