Experience of Xenoplast Drainage Using in Non-penetrating Surgery of Primary Open-angle Glaucoma

Purpose : to evaluate the hypotensive efficacy and safety of Xenoplast drainage in non-penetrating surgery of primary open-angle glaucoma. Materials and methods . The analysis of the medical records of 157 patients (157 eyes) with primary open-angle glaucoma who underwent hypotensive non-penetrating surgery (non-penetrating deep sclerectomy — NDSE) using Xenoplast drainage (group 1) and without drainage (group 2). The results were evaluated for up to 36 months. Results . The positive effect of the operation, including absolute and relative success, was 96% in group 1 on day 6, then gradually decreased and was 74 % after 36 months. In group 2, the positive effect was 100 % and decreased to 58 % at the appropriate time of follow-up. In both groups, in the early postoperative period, there was a low percentage of eye complications (5.4 % and 4.8 %), typical for non-penetrating antiglaucoma surgeries. The number of descemetogoniopunctures, performed as the second stage of NDSE, was insufficient, both in the 1st group — 42 %, and in the 2nd — 51 %. Conclusion . All of the above points to the advantage of using Xenoplast drainage during non-penetrating deep sclerectomy.
