[Laser gonioplasty in the treatment of primary chronic closed angle glaucoma].

The aim of the study was to evaluate of Nd:YAG laser gonioplasty performed together with iridectomy in the patients with primary chronic closed angle glaucoma. The results were compared with those achieved in patients with the same disease in whom only Nd:YAG laser iridectomy was done. In the first group normalization of the intraocular pressure was achieved in 64% and in the second only in 29% of the eyes. The best results were observed in cases with duration of the glaucoma less than 2 years and with intraocular pressure before treatment lower than 38 mmHg.
