Abstract

PurposeTo evaluate the outcome of trabeculectomy versus Ahmed glaucoma valve (AGV) surgery in patients with Fuchs uveitis Syndrome (FUS). MethodsTwenty-eight eyes with uncontrolled glaucoma and at least 6 months of follow-up were enrolled. In 16 eyes trabeculectomy and in 12 eyes AGV implant were performed. The primary outcome measure was surgical success defined as 5 < intraocular pressure (IOP) ≤ 21 mmHg (criterion A) and 5 < IOP ≤ 16 mmHg (criterion B), with at least 20% reduction in IOP, either with no medication (complete success) or with no more than preoperative medications (qualified success). The sum of complete and qualified success was defined as cumulative success. ResultsThe mean age of the patients in the trabeculectomy group and the AGV group was 44.92 ± 9.02 and 45.76 ± 7.10 years, respectively (P = 0.79). The mean duration of follow-up was 23.06 ± 12.03 months in the trabeculectomy group and 22.83 ± 13.63 months in the AGV group (P = 0.96). The baseline mean IOP in trabeculectomy was 26.81 ± 6.69 mmHg which decreased to 11.61 ± 4.15 mmHg at last visit (P < 0.001). In the AGV group, mean IOP was 31.41 ± 6.76 at baseline that changed to 22.41 ± 5.09 at last visit (P = 0.005). According to criterion A, cumulative success rates were 100% and 91% at 6 months and 76% and 9% at 36 months in the trabeculectomy and the AGV group, respectively. Cumulative success rates at 6 months were 93% and 58% and 65% and 7% at 36 months according to criterion B in the trabeculectomy and the AGV group, respectively.Kaplan-Meier survival analysis revealed a significant association between surgical method and cumulative success rate over 36 months (based on criteria A: P = 0.02, and based on criteria B: P = 0.007). ConclusionThe success rate of trabeculectomy was higher than AGV in the surgical management of glaucoma in FUS during a medium-term follow-up.
