Modified sutureless sclerotomies in pars plana vitrectomy.

Abstract

To study the effectiveness and safety of a modified sutureless sclerotomy technique in pars plana vitrectomy. We rotated the scleral tunnels of the original sutureless sclerotomy technique through 90 degrees, thus rendering them parallel to the corneoscleral limbus. This modified technique was applied to 25 consecutive eyes (25 patients) that had pars plana vitrectomy during a 2-month period. Twenty (80%) of 25 eyes (25 patients) did not require suturing of the sclerotomy sites associated with pars plana vitrectomy. Eight (11%) of 75 sclerotomy sites required suturing to ensure watertight closure. No clinically significant complications were encountered. The modified sutureless sclerotomy technique was found to be safe, more convenient, and easier to perform, especially in eyes with small interpalpebral space.
