[Long-term results of trabeculectomy in patients with open angle and angle-closure glaucoma].

PURPOSE: To provide data on the long-term results of trabeculectomy performed in open angle and in chronic angle-closure glaucoma. MATERIAL AND METHODS: Fifty nine eyes of 51 patients, underwent trabeculectomy from 1992 to 1994 in the Department of Ophthalmology, Medical University of Lodz. The follow up was minimum 10 years. Such pre- and postoperative measurements, as: visual acuity, intraocular pressure (IOP), visual field and the use of hypotensive medications, were evaluated. RESULTS: Successful IOP control was obtained in 91%. After 10-years follow-up the average IOP was 15 mmHg. The decrease in visual acuity was found in 25% of eyes, caused mainly by cataract. In 71% of eyes (10 years after surgery) additional topical medication was required. CONCLUSIONS: Trabeculectomy is effective and very often performed surgery in glaucoma.
