[Trabeculectomy-iridencleisis combined with cataract extraction]

On 31 eyes (23 patients, average age 74 years) with cataract and primary open-angle or chronic angle-closure glaucoma modified trabeculectomy with lobelike iridencleisis was performed combined with cataract-extraction. They were followed up for periods between 6 months and 3 years. In 84% of cases the i.o. pressure continued to be normalized without further antiglaucomatous therapy, in 16% additional treatment with drugs achieved sufficient lowering of i.o. pressure. In nearly all of the cases I observed a diffuse, very flat filtering bleb. Gonioscopy shows, that filtering channels stay open along the margin of the imbedded iris flap. Complications were rare and demanded no further surgery.
