[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.
