Releasable Suture Technique

Abstract

Releasable scleral flap sutures have been effectively used with trabeculectomy to provide a safer postoperative course. This review will assess the indications for using releasable sutures, with the consideration of their advantages and disadvantages, after trabeculectomy. A review of the literature provided the most common releasable suture techniques. Releasable scleral flap sutures reduce the incidence of complications of early postoperative overfiltration after trabeculectomy. As a result, there are fewer cases that might require reformation of the anterior chamber and drainage of suprachoroidal fluid. In contrast to performing laser suture lysis; there is no need for a laser, suture visibility under the conjunctiva is irrelevant, and no contact lens is required. The use of releasable scleral flap sutures in guarded filtration surgery safely provides an effective and simple way of titrating intraocular pressure postoperatively. It allows the transition from a relatively low flow state to a higher rate of subconjunctival filtration to achieve a satisfactory long-term outcome of glaucoma surgery.
