Comparative analysis of the dynamics of the hypotensive efficiency of sinustrabeculectomy with autoscleral drainage and standard sinus-trabeculectomy in the treatment of primary open-angle glaucoma

Abstract

Background. The method of modified sinus-trabeculectomy with autoscleral drainage of the anterior chamber and suprachoroidal space was developed at the Department of Ophthalmology in the Peoples' Friendship University of Russia. To assess the antihypertensive efficacy, a comparative analysis of the results with the method of standard sinus-trabeculectomy was carried out. Aim. To compare the dynamics of the results of hypotensive efficiency of the method of modified sinus-trabeculectomy with autoscleral drainage and standard sinus-trabeculectomy in the surgical treatment of Primary open-angle glaucoma (POAG). Material and methods. The results of surgical treatment in 75 patients (75 eyes) with primary open-angle glaucoma were studied. Patients were divided into two groups: the first group of 37 patients who were operated by modified sinus-trabeculectomy with autoscleral drainage of the anterior chamber and suprachoroidal space of autosclerosis, the second group (control) of 38 patients who underwent standard sinus-trabeculectomy. The follow-up period was 18 months. Findings. In the remote postoperative period (after 18 months.) in the first group, 36 patients had normalization and stabilization of ophthalmo-tonus (IOP P (0) averaged 14.6±1.4 mm Hg in one(1) case, there was a moderate increase in the level of IOP, for which hypotensive therapy (beta-blockers) was prescribed. In the second group, IOP P (0) averaged 18.1±1.1 mmHg, the normalization of IOP was observed in 35 patients, in three (3) cases there was an increase in the level of IOP, for which hypotensive therapy (beta-blockers) was also prescribed. Conclusion. The highest and persistent hypotensive effect and fewer failures were achieved after the modified sinustrabeculectomy technique using autoscleral drainage.
