[Comparative examinations in goniotrepanation and trabeculectomy (author's transl)].

In 20 patients with glaucoma simplex (15 cases) or angle closure glaucoma (5 cases) a trabeculectomy had been done on one eye and a goniotrepanation on the other eye within a period of a few days. As far as the operation-technic concerns neither ofthe two methods revealed a remarkable advantage nor a disadvantage. All patients have been controlled up to one year after the operations. There were only a few postoperative complications in both groups. There was no significant difference in the regulation of the intraocular pressure.
