Relevance. Arterial hypotension negatively affects eye function. It is known that 'glaucoma' and 'elevated intraocular pressure' are not synonymous. There can be ocular hypertension without signs of glaucoma, and glaucoma can occur without elevated intraocular pressure. Elevated IOP is not an absolute sign of glaucoma. This fact drives researchers to explore other causes of glaucomatous optic neuropathy. Purpose of the study. To study the clinical course of glaucoma with low ophthalmotonus among residents of Dushanbe. Materials and methods.The study established that 16.1% of individuals with normotensive glaucoma had arterial hypertension, 64.5% had arterial hypotension, and 19.4% had normal arterial pressure. Patients underwent standard examinations: biomicroscopy, ophthalmoscopy, visual acuity measurement, gonioscopy, perimetry, tonometry, and echobiometry. Tolerant pressure was determined using A.M. Vodovozov's method, where patients received a mixture of glycerol ascorbate, 50% glycerin at a dose of 1.5 g/kg body weight, with ascorbic acid 0.1 g/kg. After three cycles of dicainization, IOP was measured with a Maklakov tonometer (10 g) every 30 minutes for one hour. The tolerance level was established as the level at which pressure readings stabilized. The intolerance index was calculated as the difference between tonometric and tolerant pressures. A mandatory condition for inclusion in the study was theabsence of prior laser or surgical interventions on the examined eye. Results and conclusion. Among 40 patients (80 eyes), the anterior chamber angle was open in 32 patients (64 eyes) and closed in 8 patients (16 eyes). Visual acuity decreased with the progression of glaucoma, with visual acuity of 0.9-1.0 in 14% of eyes, 0.7-0.8 in 25%, 0.4-0.6 in 29%, and 0.1-0.3 in 32% of eyes. Arterial hypotension negatively affected the vascular system of the eye, leading to a constriction of the visual field. Microscotomas were detected in the lower inner segment in 57% of patients, single scotomas were observed in 13% of patients with normal blood pressure, and nasal scotomas were found in 30% of individuals with low blood pressure. In patients aged 40-49 years, IOP was recorded at 17±1.0 mm Hg. Glaucoma with low intraocular pressure is characterized by early onset and significant changes, including dystrophic changes in the anterior chamber angle, optic disc alterations, and peripheral visual field narrowing.
