to compare the efficacy and safety of trabeculectomy with or without adjustable flap sutures and anterior chamber (AC) maintainer.
32 patients (64 eyes) were included in this prospective study. One eye of each patient was randomly assigned to a trabeculectomy with 2 adjustable and 2 releasable flap sutures + an AC maintainer (technique 1) while the other eye had a trabeculectomy with 2 releasable flap sutures + a viscoelastic (technique 2). The rest of the operation was similar in both eyes. Mitomycin-C was used in 50% of the patients in each group. The postoperative management was equal in both groups except for the manipulation of the adjustable sutures. The main outcome measures were the intraocular pressure (IOP) and the frequency of early postoperative complications.
32 patients were included and had a follow-up of at least 24 months. The mean pre- and postoperative IOP at 24 months was 22.1 ± 7.6 and 13.3 ± 2 mmHg for technique 1, and 22.7 ± 6.8 and 13.3 ± 3.4 for technique 2 (p=0.18). Early postoperative complications were infrequent and comparable in both techniques.
the efficacy and safety of both trabeculectomy techniques were comparable.
