Does 23-gauge sutureless vitrectomy modify the risk of postoperative retinal detachment after macular surgery? A comparison with 20-gauge vitrectomy.

Purpose: To compare the cumulative risk of retinal detachment (RD) after macular surgery with 23-gauge sutureless vitrectomy and with 20-gauge vitrectomy.

Methods: A single-center retrospective comparative study was conducted, comparing eyes operated for epiretinal membrane, macular hole, vitreomacular traction, and internal limiting membrane peeling. The 23-gauge group included 349 eyes operated consecutively between June 2007 and December 2008.
