Micropulse cyclophoto-coagulation in patients with primary open-angle glaucoma: early results

Abstract

Aim – to evaluate the efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) procedure in patients with primary open-angle glaucoma (POAG). Material and methods. The study was conducted in 21 patients with POAG and uncompensated intraocular pressure (IOP) using pharmacotherapy. All patients underwent MP-TSCPC procedure with IRIDEX Cyclo G6 device. The follow-up period lasted for 1 month. During this time, the visual acuity, IOP dynamics, complications, as well as the number of hypotensive drugs used were evaluated. Statistical analysis was performed using STATISTICA 12.0 software. Results. Among patients with moderate and advanced glaucoma, the IOP reduced by 46.7 (3.3; 64.3) % from baseline values by the end of the follow-up period. The target IOP was achieved in 30.7% of patients. In 75% of patients who achieved target IOP, the number of hypotensive drops used was reduced by 1 component. In all patients with terminal stage glaucoma, pain was relieved, and IOP was reduced by 35.5 (8.4; 41.1) %. No intra- or postoperative complications were reported in any case. Conclusion. MP-TSCPC can be considered as a relatively safe adjunctive method to achieve target IOP in addition to medical treatment in patients with moderate and advanced glaucoma, as well as appropriate method to control pain in patients with the terminal stage of the disease.
