PURPOSE: Our aim was to compare surgical outcomes of trabeculectomy and nonvalved glaucoma-drainage-device (GDD) implantation in eyes with chronic inflammatory glaucoma and uncontrolled intraocular pressure (IOP). METHODS: A retrospective chart review was conducted on patients with glaucomatous optic neuropathy, chronic anterior or posterior segment inflammation, and ≥6 months postoperative follow-up. All eyes underwent trabeculectomy with either antifibrotic therapy or implantation of a Baerveldt GDD (Abbott Laboratories Inc., Abbott Park, IL, USA). Failure was defined as IOP >21 mmHg, <20 % reduction below baseline or IOP <5 mmHg on two consecutive follow-up visits after 3 months, reoperation for glaucoma, or loss of light-perception vision. Statistical methods consisted of Student's t tests, χ(2) test, and Kaplan-Meier time to failure analysis. RESULTS: Nineteen trabeculectomies of 42 patients were followed for a mean of 31 ± 23 and 23 GDD eyes for a mean of 39 ± 19 months (P = 0.22). At last follow-up, mean IOP (11.83 ± 4.59 and 13.15 ± 6.11 mmHg, P = 0.45) and number of glaucoma medications (1.28 ± 1.56 and 1.26 ± 1.25, P = 0.97) were similar between the trabeculectomy and GDD groups. The frequency and types of postoperative complications in both groups were similar. The cumulative probability of failure after 5 years of follow-up was significantly greater in trabeculectomy eyes (62 %) compared with GDD eyes (25 %) (P = 0.006). CONCLUSIONS: Nonvalved tube-shunt surgery was more likely to maintain IOP control and avoid reoperation than trabeculectomy with antifibrotic therapy in eyes with chronic inflammatory glaucoma.
