[Long-term results of laser-trabecular-puncture (author's transl)].

A report on 38 eyes with glaucoma simplex that were treated by laser-trabecular-puncture 2 years ago is given. By this method one attempts to perforate the trabecular meshwork by means of a laser beam. Gonioscopy revealed that the pores had become occluded by scar tissue and goniosynechiae. In only 3 eyes (7.9%) was the intraocular tension lowered. The hypothesis is made, that in these cases contracture of scar tissue in the iris tissue led to a pull on the trabecular network and hence to an improvement of liquor drainage.
