[Transtrabecular iridectomy - a new surgical technique in the treatment of chronic narrow-angle glaucoma (author's transl)].
A new surgical technique in the treatment of chronic narrow-angle glaucoma is described. After forming a scleral flap and opening of Schlemm's canal a probe is inserted into the canal. We dissect the sclera and the outer wall of Schlemm's canal by an oblique cut. The probe being retracted again, the trabecular meshwork is cut and a basal iridectomy is performed. Then the scleral cut and the trabecular window are closed tightly. Postoperative pressure behaviour and gonioscopy indicate, that the outflow of aqueous humour occurs via trabecular cleft and the collector channels in the operating field; obviously with this technique the intrascleral outflow channels can be saved to a great extend.
