PURPOSE: To describe the preoperative prognostic factors that correlate with the surgical success of goniosurgery for glaucoma complicating chronic anterior uveitis and to describe the surgical technique. METHODS: The medical records of 31 patients with 31 eyes with glaucoma secondary to chronic anterior uveitis for which 38 goniotomy procedures were performed were reviewed. Uveitis etiology, gender, age of onset of iritis, duration of iritis before recognition of glaucoma, duration of iritis and duration of glaucoma until initial goniosurgery, preoperative gonioscopic findings, lens status, surgical outcome, age at initial goniosurgery, duration of postoperative observation, lens status, preoperative and postoperative intraocular pressures, topical steroid, and glaucoma medication use were reviewed. Complete success was defined by an intraocular pressure (IOP) < or = 21 mm Hg, and qualified success as IOP < or = 21 mm Hg with use of glaucoma medications. The surgical technique used to perform the goniosurgery was reviewed. RESULTS: Overall surgical success was achieved in 22 (71%) of 31 eyes. The mean age at surgery was 10.2 +/- 4.2 years (range, 4-21 years). All but 8 patients were female. Mean follow-up interval was 10.3 +/- 6.4 years (range, 1.5-22 years). Significant correlation was found between outcome and age at initial surgery, lens status, duration of glaucoma before goniosurgery, duration of iritis before glaucoma surgery, and hours of peripheral anterior synechia (PAS). The mean number of clock hours of preoperative (PAS) was 0.5 hours in eyes with success versus 2.5 hours in eyes with failure. Age of onset of iritis, duration of iritis before recognition of glaucoma, trabecular meshwork pigmentation (TM), TM opacification, and circumferential ciliary body band narrowing did not correlate with surgical outcome. CONCLUSION: Goniosurgery is an effective treatment of glaucoma secondary to chronic anterior uveitis. The outcome of surgery was unfavorably influenced by older age, longer duration of glaucoma, and evidence of more advanced preoperative filtration angle abnormalities secondary to uveitis. Goniosurgery for this secondary glaucoma can be successfully performed utilizing the standard goniotomy technique.
