The purpose of study is to evaluate the effectiveness of antiglaucomic operations with the use of the Ex-Press mini glaucoma shunt and Repegel-1 drainage in patients with primary open-angle glaucoma. Material and Methods. 65 patients (65 eyes) with an established diagnosis of uncompensated primary open-angle glaucoma of Stage III were observed. All patients underwent anti-glaucoma surgery. Patients of group 1 (15 patients, 15 eyes) underwent penetrating deep sclerectomy with implantation of the Ex-Press mini shunt under the scleral flap. Patients of group 2 (25 patients, 25 eyes) — penetrating deep sclerectomy with Repegel 1 drainage. Patients of group 3 (25 patients, 25 eyes) underwent sinus trabeculectomy without drainage. Results. In the early postoperative period, a good hypotensive effect was obtained in patients of all three groups. The most persistent antihypertensive effect was obtained in patients who underwent anti-glaucoma surgery with Repegel-1 drainage implantation. In patients who were implanted with the Ex-Press mini shunt, there was a significant decrease in the perimetrical MD index for 3 months. Conclusions. 1. Improvement of the photosensitivity of the retina in patients who underwent an antiglaucoma operation with Ex-Press shunt implantation, possibly due to the low invasiveness of the intervention and the absence of a sharp drop in IOP level. 2. Preliminary results (analysis 3 months after the operation) indicate a lower number of postoperative complications in the implantation of Repegel-1 drainage and a persistent hypotensive effect. 3. Patients who underwent antiglaucoma operations with implantation of drainage systems showed improvement of hemodynamic parameters in the pool of posterior short ciliary arteries in the postoperative period.
