[Non-penetrating deep sclerectomy in the treatment of advanced cases of open angle glaucoma].

PURPOSE: The purpose of the paper was to examine the efficacy of non-penetrating deep sclerectomy (NPDS) with sodium hyaluronate implants and mitomycin C in the treatment of advanced cases of open angle glaucoma. MATERIAL AND METHODS: Thirty-five eyes of 35 patients with medically uncontrolled advanced open angle glaucoma were retrospectively analyzed. Visual acuity and intraocular pressure measurement were performed before and after surgery at 1 and 7 days and 1, 6 and 12 months. Visual field was analyzed before and 12 months after surgery. RESULTS: The mean preoperative intraocular pressure was 27+/-3.1 mm Hg and 18.1+/-1.5 at 12 month after surgery (p 0.05). Complete success rate defined as an IOP lower than 21 mmHg without medications was 51%. In 3 eyes we performed needling and in 8 goniopuncture. Postoperative complications included hyphaema in 3 eyes, choroidal detachment in 1 eye, bleb fibrosis in 2 eyes. CONCLUSIONS: 1. Deep sclerectomy with SK-GEL implant and antimetabolites provided good reasonable control of intraocular pressure. 2. In uncomplicated cases it let us achieve stabilization of the visual field.
