Sutureless revision of overhanging filtering blebs

Abstract

We describe methods and outcomes of a technique for sutureless surgical revision of symptomatic corneal overhanging filtering blebs after trabeculectomy using mitomycin in 6 eyes in 6 patients. Separation of the bleb from the corneal surface was achieved by blunt or sharp dissection, as necessary, and the overhanging portion of the bleb was excised and a bandage contact lens was inserted. Outcome measures included symptomatic relief, retention of bleb function, and maintenance of intraocular pressure. Five eyes (83.3%) demonstrated symptomatic relief and a cosmetically acceptable appearance. One patient continued to have dysesthesia, and 1 patient had bleb leak that required suture repair. Sutureless surgical revision of overhanging filtering blebs is a safe and effective technique to reduce bleb-related dysesthesia and improve cosmesis without compromising filtration function. ©2006 American Medical Association.
