| description | Purpose. To evulate the efficiency of micropulse cyclophotocoagulation (MP-CPC) in the combined treatment of patients with secondary refractory neovascular glaucoma with object vision. Material and methods. The study involved 30 patients (30 eyes) with neovascular glaucoma (NVG) in the stage of partial or complete blockade of the iridocorneal angle with decompensated intraocular pressure (IOP) resistant to drug therapy, who had object vision. Two study groups were formed, 15 eyes each. The first main group is represented by patients whom performed MP-CPC (Cyclo G6 Glaucoma Laser System by IRIDEX), as a stage of combined treatment before implantation of Ahmed glaucoma valve (IAGV). The second control group included patients who initially were treated by this type of drainage surgery without preliminary micropulse laser exposure. The follow-up period was 18 months. Results. The implementation of MP-CPC in the main group led to a significant decrease in IOP on the 1st day after treatment from 27.5±6.1 to 23.6±4.6 mm Hg, with the maximum attainment of normal values on the 3rd day of observation, which averaged 20.3±4.4 mm Hg. (p<0.05). By the end of the 1st month, an increase in mean IOP values to subcompensated values was recorded – 24.4±6.3 mm Hg. After valve drainage implantation, by the end of the 1st month of observation, IOP in the main group was 19 (16.5; 22.0) mm Hg, and in the control group it was 24.5 (20.5; 25.8) mm Hg. (p<0.05). After 18 months of the postoperative period, the level of ophthalmotonus in the main group is 15.5 (15.0; 18.2), and in the control group – 16.5 (15.0; 19.5) mm Hg. (p>0.05). A significant decrease in the amounts of hypotensive drugs in the main group was revealed: 1 (0; 2) versus 2 (1; 3) in the control group (p=0.03). In both groups, there was no significant deterioration in visual functions during the entire observation period. Conclusions. MP-CPC can be considered as a preliminary stage in the combined treatment of neovascular refractory glaucoma, as it reduces the risk of preoperative ophthalmohypertension before valve surgery, leads to a significant decrease in the amounts of hypotensive drugs in the late postoperative period, thereby improving the effectiveness treatment of patients with neovascular refractory glaucoma who have object vision. |
