Clinical experience of combined laser treatment of patients with primary open-angle glaucoma (preliminary results)

Purpose: to investigate the results of combined laser treatment of patients using YAG-laser activation of the trabecula and Micropulse transscleral cyclophotocoagulation (MTC). Materials and methods: The present study was performed on 43 patients (43 patients) diagnosed with POAG, the developing stage, in 1st group (22 eyes) and control (21 eyes) group. The patients age ranged from 61 to 82 years (mean age 70.4±1.2 years). IOP in all patients was compensated on antihypertensive drops and on average 19.36±1.36 mm Hg in the 1sl group, 19.45±1.15 mm Hg in the control group. The number of antihypertensive drugs used before surgery ranged from 2 to 3 (average 2.13±013 in the experimental group, 2.19±0.4 in the control group). YAG-LAT was performed with a Lightlas YAG Nd-YAG laser from Lightmed (USA). The MTC was performed using a Cyclo G6 Glaucoma Laser System (IRIDEX, USA). In the experimental group, all patients underwent YAG-LAT with mTc, in the control group - MTC. Patients were observed on the 1st, 7th day, then after 1, 3 and 6 months after the treatment. The results obtained were summarized in the form of a table and subjected to statistical processing. Results: On day 1 after the intervention in the experimental group, IOP was (mm Hg): 19.36±1.36, in the control group-19.45±1.15, on day 7: experimental group-20.59± 1.5, control - 19.9±2.68, 1 month: experimental group - 13.95±1.67, control - 15.8±1.5, 3 months: experimental group: 15.04±1.13, control : 16.48±1.12, 6 months: experimental group - 15.27±1.77, control: 16.23±1.41. Conclusion: Combined laser treatment of patients, including YAG-laser activation of the trabecula and MTC, is an effective and safe method for lowering intraocular pressure in patients with glaucoma.
