The Importance of Ultrabiomicroscopy in the Diagnosis of Open-Angle Glaucoma in the Early Stages

Abstract

Open-angle glaucoma is a syndrome of optic nerve damage associated with an open angle of the anterior chamber and increased or, sometimes, average intraocular pressure (IOP). Open–angle glaucoma is in second place among eye pathologies leading to irreversible vision loss, therefore, the study of the causes, identification of early symptoms, treatment and prevention of this disease is a priority in scientific and practical ophthalmology.

Purpose: The purpose of our study is to study and determine the indicators of the patency of the angle anterior chamber obtained by ultrasound biomicroscopy (UBM) in primary open–angle glaucoma (POAG).

Materials and methods: 30 people (60 eyes) participated in the study: in the observation group there were 15 patients with OAG (30 eyes), in the control group there were healthy individuals (15 people – 30 eyes) without ocular pathology and with normal values of intraocular pressure (IOP). The study did not include patients who had undergone surgery, trauma, uveitis, PES with dislocation of the lens, as well as with clinically diagnosed swelling cataract, which obviously can become the leading  the reason for the change in anatomical and topographic parameters.
