[Trabeculectomy and nonpenetrating surgery in glaucoma]

The purpose of the study is to compare the efficiency of classical trabeculectomy and with the punch and nonpenetrating deep-sclerectomy in patients with primary open angle glaucoma. The studied groups comprise patients with uncontrolled intra-ocular pressure with medical therapy and/or laser. The results of the study emphasize the following conclusions: the decrease of intra-ocular pressure is comparable in classical trabeculectomy and with punch the decrease of intra-ocular pressure is comparable in classical trabeculectomy and nonpenetrating surgery. we consider the non penetrating surgery an interesting alternative to the classical trabeculectomy, with better control of intra-ocular pressure the complications of non penetrating surgery are reduced.
