Algorithm for Performing Laser Iridectomy in Patients with Angle-Closure Glaucoma and Concomitant Somatic Pathology

Abstract

Тhe main treatment for angle-closure glaucoma is laser iridectomy. Somatic comorbidity (autoimmune, allergic, chronic infectious diseases) affects the results of laser iridectomy.Purpose: to evaluate in practice the algorithm for applying the method of laser iridectomy in compliance with preventive measures, including medical support before and after surgery, both in patients with concomitant somatic pathology and without it.Patients and methods. The analysis of combined laser iridectomy’s results in 61 patients (94 eyes) was carried out. A method was used to determine the tactics of management the patients with latent stage of angle-closure glaucoma and pigment dispersion syndrome (Patent RU N 2726404), including an assessment of the general immune status based on information about somatic diseases and medications taken. Combined laser iridectomy was performed in two stages in one visit. The first stage is coagulation in the projection of the lacunae at the periphery of the iris; at the second stage, two through holes were formed. All patients received medication in accordance with the algorithm. The level of reactive hypertension was assessed in 1 hour after surgery, on the first and seventh days after the intervention.Results. In case of standard medical support for laser iridectomy, the level of reactive hypertension is higher in the group of patients with concomitant somatic pathology than without it. Adding additions to the standard drug regimen in a group of patients with impaired general immune status ensures that the target intraocular pressure is achieved. The use of an algorithm for performing laser iridectomy in patients with angle-closure glaucoma and concomitant somatic pathology makes it possible to achieve the target intraocular pressure early after surgery and to avoid complications.
