Abstract

Fourteen eyes (12 with open-angle glaucoma and 2 with secondary glaucoma) of 14 patients were operated by trabeculectomy at the inferior limbus. The surgical technique is described and results of 6-12 months follow-up are reported. Complication rate was reasonably low. Early postoperative IOP higher than 30 mmHg occurred in one eye where a blood clot and sodium hyaluronate obstructed filtration of aqueous. Postoperative mean IOP was 16.3 mmHg (6-29 mmHg) in 13 eyes at 3 months, 17.1 mmHg (13-26 mmHg) in 12 eyes at 6 months and 20.1 mmHg (11-31 mmHg) in 12 eyes at 12-16 months. Three eyes had follow-up of 19-21 months and corresponding IOPs were 14, 15 and 22 mmHg. IOP was less than 22 mmHg in 10/12 eyes at 6 months and in 8/12 eyes at 12-16 months. 6/12 eyes managed without medication at 6 months and 2/12 eyes at 12-16 months. Trabeculectomy at inferior limbus is a safe procedure and it is recommended as a surgical procedure in eyes after previous cataract surgery.
