Trabeculectomy in the second eye.
Trabeculectomy has a reported success rate of between 67-94%. Many studies have been performed on operative variables which may influence surgical outcome. Youth, pigmented race and anterior segment inflammation have been shown to be associated with trabeculectomy failure. Little is known of the surgical outcome of trabeculectomy in one eye in relation to its partner, when surgery is standardized and the above known adverse conditions to trabeculectomy success are absent. We therefore carried out a prospective study on 62 patients who underwent bilateral trabeculectomies. There was a significant failure rate amongst pairs of eyes (postoperative intraocular pressure > or = 21 mmHg), with the majority of failures occurring within 6 months of surgery. Failure appeared to be associated with a longer period from diagnosis of glaucoma to surgery, and the use of a wider variety and number of topical medications. All other trabeculectomy complications occurred more commonly in any single eye, than in any pairs of eyes.
