    Abstract:
    PURPOSE: To compare the outcomes of Aurolab aqueous drainage implant (AADI; Aurolab) placement and trabeculectomy with mitomycin C (MMC) in patients with glaucoma secondary to aniridia. DESIGN: Retrospective comparative interventional case series. METHODS: This study included patients with congenital aniridia who underwent AADI implantation or trabeculectomy with MMC. Surgical failure was defined as IOP > 21 mm Hg or reduced <20% from baseline, IOP ≤ 5 mm Hg, reoperation for glaucoma or a complication, or loss of light perception vision. RESULTS: A total of 30 eyes of 30 patients underwent surgical treatment, including 18 eyes that received an AADI and 12 eyes that had a trabeculectomy with MMC. The cumulative probability of failure at 2 years was 11.1% (95% CI = 2.9%-37.6%) in the AADI group and 58.3% (95% CI = 33.5%-84.8%) in the trabeculectomy group (P = .05, log-rank). At 2 years, IOP (mean ± SD) was 14.1 ± 2.8 mm Hg in the AADI group and 19.6 ± 6.6 mm Hg in the trabeculectomy group (P = .02), and the number of glaucoma medications was 1.7 ± 0.9 in the AADI group and 2.2 ± 0.8 in the trabeculectomy group (P = .25). Surgical complications developed in 1 patient in each treatment group (P = .65). Cataract surgery was performed in 5 (42%) patients in the trabeculectomy group and no patients in the AADI group (P = .01). CONCLUSIONS: Placement of an AADI resulted in lower IOP and a higher rate of surgical success compared to trabeculectomy with MMC in eyes with glaucoma associated with aniridia. Cataract extraction was more frequently required after trabeculectomy with MMC than AADI implantation.
