Purpose. To evaluate the effectiveness of surgical resection of the sclera in patients with primary open-angle and secondary glaucoma. Materials and methods. The study included 84 patients with POAG and SG stages III-IV and decompensated IOP level (not higher than 32 mm Hg). In order to normalize the increased ophthalmotonus, a non - penetrating operation was performed-surgical resection of the sclera (SRS). The patients underwent complex ophthalmological examination and dynamic observation. Result. In the studied groups of patients after surgical treatment there was a decrease in elevated IOP levels by 33.42%, an improvement in the coefficient of ease of outflow and a weakening of the hypotensive regime. Stabilization of visual functions was observed in all patients. Summary. The proposed new SRS technique provides a smooth decrease in IOP, preservation of visual functions and is not accompanied by intra-and postoperative complications. Key words: primary open-angle glaucoma, surgical resection of sclera, secondary glaucoma, uveoscleral outflow pathway (USPO), intraocular pressure, EO coefficient .

The uveoscleral outflow as an alternate route of aqueous drainage is of great interest in glaucoma surgical treatment. A cyclodialysis cleft allows one to create a direct connection between the anterior chamber (AC) and the suprachoroidal space (SCS) which is the key element of uveoscleral outflow. The purpose of the study was to evaluate the safety and effectiveness of reverse meridional cyclodialysis ab interno (RMCai) in decreasing intraocular pressure (IOP) in patients with primary open-angle glaucoma (POAG) and refractory glaucoma (RG). Fourteen patients who exhibited POAG and RG (11 men and 3 women, age 77.3 ± 7.8 years) were included in the study. All patients underwent RMCai with the help of custom-designed spatula. The spatula, inserted through a clear corneal incision, was used to detach the ciliary body from the scleral spur to create a 2.0–2.5 mm wide and 6.0–6.5 mm deep cleft. Outcome measures were IOP change, use of hypotensive medication(s), complications, and need for a second surgery. Decrease in IOP by more than 20% and IOP between 6 and 21 mmHg without hypotensive medication constituted complete success. Similar changes in IOP with medication constituted partial success. Need for second surgery constituted failure. The follow-up period was >3 months. Baseline IOP and hypotensive medication use were 22.0 ± 8.5 mmHg (95% confidence interval (CI), 17.6–26.4) and 2.6 ± 0.9 (95% CI, 2.2–3.1). At 3, 6, 12, 18, and 24 months, complete success was achieved in 64.3%, 77.8%, 55.6%, 37.5%, and 40% of patients respectively; partial success — in 14.3%, 22.2%, 44.4%, 50.0%, and 60.0%. Four patients required a second surgery. Failure occurred because of cleft closure by fibrosis. It was concluded that RMCai is safe and effective in decreasing IOP in POAG and RG patients.
