Incisional therapies: Trabeculotomy surgery in adults

Abstract

Glaucoma patients who require incisional glaucoma surgery and who neither are optimal candidates for filtering surgery nor need an intraocular pressure (IOP) as low as 10 mmHg may be candidates for trabeculotomy. Trabeculotomy ab externo is an anterior chamber angle procedure designed to increase conventional trabecular outflow. IOP is lowered without creating a filtering bleb. Patients with only mild to moderate disc damage and with uncontrolled IOPs greater than 21 mmHg may do well with postoperative IOPs in the mid-to late teens and perhaps just one antiglaucoma medication - the typical scenario post-trabeculotomy surgery (Fig. 66.1a, b). © 2010 Springer-Verlag New York.
