[The role of iridectomy in glaucoma surgery]. / Rolul iridectomiei periferice în chirurgia antiglaucomatoasa.

ABSTRACT

PURPOSE: analysis of the influence of peripheral iridectomy on the efficiency and safety of trabeculectomy and phacotrabeculectomy in patients with open-angle glaucoma. METHODS: interventional, prospective, randomized and comparative study with two groups 44 eyes with trabeculectomy (group 1) and 24 eyes with phacotrabeculectomy (group 2). Each of the two groups was divided into two main subgroups (with and without iridectomy), compared with each other in terms of efficacy and safety of surgical procedure. RESULTS: Iridectomy was performed on 22 eyes in group 1 (subgroup 1A) and on 12 eyes in group 2 (subgroup 2A), the remaining cases in each group forming subgroups without peripheral iridectomy (subgroup 1B, 2B respectively). Statistical analysis reveals that iridectomy does not seem to influence the efficiency of filtration procedure, regardless of the postoperative moment of analysis (early or final). In all four subgroups at 1 year was a significant decreasing of intraocular pressure, with a low rate of complications. CONCLUSIONS: A proper selection of open-angle glaucoma cases allows the abandonment of peripheral iridectomy in trabeculectomy and phacotrabeculectomy.
