The Results of Transscleral Diode Laser Cyclophotocoagulation in Micropulse Mode Treatment in Patients with Primary Subcompensated Open-Angle Glaucoma and Toxic-Allergic Syndrome of the Ocular Surface

Abstract

Purpose: to analysis the results of microimpulse transscleral diode laser cyclophotocoagulation (DCPC) technique as a method of choice in patients with open-angle subcompensated glaucoma (OAG) with toxic allergic syndrome of the ocular surface (TASOS).Methods. The retrospective analysis of patients’ case reports with subcompensated open-angle glaucoma and TASOS was performed. Transscleral diode laser cyclophotocoagulation (DCPC) in a microimpulse mode was used in their treatment. A total of 19 patients’ case reports were analyzed.Results. In the postoperative period, its course, patient’s complaints, ophthalmological status, visual acuity indicators were determined. The level of intraocular pressure was measured. Almost all patients (84.2 %) reached the target level of IOP. The frequency of side effects was low. In 36.84 % of patients, symptoms of TASOS decreased in response to hypotensive treatment due to reduction of instillation frequency.Conclusion. The use of micro-pulse cyclophotocoagulation in patients with subcompensation form of OAG and toxic-allergic ocular surface syndrome (TASOS) reduces the intensity of the drop regime of antihypertensive drugs. As a result, the manifestations of TASOS are reduced, which increases the patients’ quality of life in the postoperative period. In addition, the use of DCPC in microimpulse mode leads to stabilization of functional and structural indicators, helps to prevent a decrease in visual functions. Thus, the described method is characterized by safety, high efficiency and a wide range of indications for its performance. It allows to compensate the IOP with a minimum percentage of complications and stable postoperative results.
