Modified sutureless sclerotomies for pars plana vitrectomy

PURPOSE: To describe a modified technique for performing sutureless sclerotomies for pars plana vitrectomy and to examine its efficacy and safety. DESIGN: Retrospective, interventional case series. METHODS: Self-sealing sclerotomies were created in 35 consecutive cases by oblique penetration of the sclera with a 19G MVR blade. RESULTS: All but two (2.9%) of the sclerotomies were watertight without suturing at the end of surgery. A conjunctival bleb was observed during the first postoperative week in one case, but it resolved without intervention. CONCLUSIONS: Construction of sutureless sclerotomies by this technique is simpler and more rapid compared with previously described techniques. The resulting sclerotomies are more resistant to stretching and tearing of the tunnel's roof, they rarely need suturing, and insertion of instruments is facilitated. (C) 2004 by Elsevier Inc.
