Purpose – to analyze long-term results of meridional cyclodialysis ab interno (MCai) with implantation of a supraciliary metalic implant (SMI) in decreasing intraocular pressure (IOP) in patients with glaucoma. Material. A total of 50 glaucoma cases were operated upon. In all cases MCai was performed. In the study group (29 cases), to keep the cyclodialysis cleft open, after MCai a SMI was implanted. Rest 21 cases served as control. Surgically, ciliary body was gently detached from sclera at 4-5 o'clock position with the help of a specially designed spatula inserted through a clear corneal incision, creating a cleft of 2,5 mm wide and 5-6 mm deep. Outcome measures: IOP change, use of hypotensive medications, need for repeat glaucoma surgery and complications. Minimum follow-up period – 18 months. Results. Baseline IOP, which was 28.9 ± 4.7 и 30.2 ± 7.2 mmHg in study and control groups respectively, at 18 months reduced to 19.6 ± 1.6 (р = 2Е-08) and 20 ± 1.4 mmHg (p = 0.0006). Use of hypotensive medications reduced from 2.7 ± 0.8 to 1.1 ± 0.9 (р = 1Е-06) in study group and from 2.6 ± 0.9 to 0.8 ± 0.7 (р = 2Е-05) in control group. There was no statistically significant difference between groups in relation to decrease in IOP and use of hypotensive medications. Overall success in study group was 86 %, in control group – 67 % (p = 0.12). Failure rate was 14 % in study group and 33 % – in control group (p = 0.006). Conclusion. MCai is effective in decreasing IOP and in reducing use of hypotensive medications, however MCai followed by implantation of a SMI reduces significantly number of cases requiring repeat glaucoma surgery.
