This article describes a transconjunctival technique for pars plana vitrectomy using 20-gauge instruments. Sclerotomies are performed directly through the conjunctiva, Tenon's capsule, and sclera with a 19-gauge microvitreoretinal blade. A sutureless 20-gauge infusion cannula is then inserted and pars plana vitrectomy is performed in a standardized fashion using 20-gauge instruments. Each sclerotomy and its corresponding conjunctival incision is closed with a single stitch using a 7-0 polyglactin suture. This transconjunctival technique is a reasonable alternative surgical approach to minimize surgical trauma of tissues (eg, conjunctiva) and hasten postoperative recovery without the additional risks and costs associated with 25-gauge pars plana vitrectomy.
