Background: Neovascular glaucoma (NVG) is a highly refractory form, it is characterized by fast development and a high level of the intraocular pressure (IOP). Aims: To evaluate the effectiveness of micropulse transscleral cyclophotocoagulation (mCPC) in the combined treatment of patients with secondary neovascular glaucoma. Methods: The study included 32 patients (32 eyes) with secondary NVG as an outcome of diabetes mellitus and (or) thrombosis of the central retinal vein or its branches. The preoperative IOP averaged 38.88.8 mm Hg with the most intense hypotensive therapy. All the patients underwent mCPC. In the postoperative period, the patients were examined on the first day after the operation, then in 1 week, 1, 3, 6 months, 1 year after the operation. Results: All the operations were performed without complications. Pain syndrome in all cases was stopped on the first day after surgery. Six patients had reactive hypertension on the first day, therefore, the hypotensive therapy was intensified. The IOP 1 week after mCPC was 20.97.9 mm Hg, after 1 month of observation 23.76.0 mm Hg with the hypotensive therapy. 34 weeks post-surgery, six patients with the preserved visual function experienced a repeated IOP increase, and the Ahmed valve was implanted. 6 months after mCPC, the IOP level averaged 22.87.7 mm Hg with the hypotensive therapy. Against the background of the IOP compensation, anti-VEGF drugs were injected in 4 cases, followed by laser coagulation of the retina. Conclusion: Application of mCPC in NVG glaucoma patients showed only a small number of postoperative complications. This method of laser treatment can be used in combination with panretinal laser coagulation before or after the surgery, including administration of anti-VEGF drugs before or after the surgery. In case of the IOP increase, mCPC may be repeated.
