Abstract

Trabeculectomy and trabeculotomy are recent development in glaucoma surgery. Results are reported to be better than with standard filtering procedures and complications are few. At the present time trabeculectomy is tbe treatment of choice for patients with simple glaucoma requiring surgery. In the period January, 1975, to March, 1976, 20 trabeculectomies were done in adult glaucoma and combined technique of trabeculectomy and trabeculotomy was done in 6 congenital glaucoma in Busan National University. We tried a modified technique of trabeculectomy, which is; (1) limbal based scleral flap was made of 1/3 in thickness of sclera, (2) 2 knots with 8-0 silk were placed in angle of scleral flap. Success was achieved in 23 eyes (88.4%) of 26 cases and the duration of follow-up ranged from 5 to 18 months. A successful trabeculectomy functions by permitting increased aqueous outflow via several pathways. We suggest that the aqueous may filter externally along the course of the scleral scar or may permeate the thinned outer scleral lamellae, producing a bleb that mayor may not be visible. The complications were hyphema, flat chamber, posterior synechia and retinal hemorrhage.
