Background: Trabeculectomy is one of the most common ophthalmic surgeries, but over filtration may cause serious ophthalmic complications. The aim of this study is to compare two suture methods in trabeculectomy.

  Materials and Methods: This clinical trial accomplished on 28 eyes of 28 patients with primary open angle glaucoma unresponsive to full medication. Patients were divided into two equal groups. In one group, standard and the other group releasable suture trabeculectomy was performed. Post-Surgery short-term complications and intraocular pressure were compared in both groups.

  Results: The mean IOP reduction in group with releasable sutures was 22.14±13.99 and in standard group was 28.14±14.10 (p=0.269). Frequency of iridocorneal touch in releasable and standard groups was 7.1 and 50 percent, respectively(p=0.016). Also, Frequency of shallow anterior chamber in releasable and standard groups was 21.4 and 92.2 percent, respectively(p<0.001).

Conclusion: Trabeculectomy with releasable suture reduces short-term complications and in this group, IOP control is equal to standard trabeculectomy.
