WAILEA, Hawaii — Microincision vitrectomy surgery can be used to manage a variety of surgical indications with few complications and a shorter operating time, according to a study presented here.

Federica Genovesi-Ebert, MD, presented data at the American Society of Retina Specialists annual meeting on 5,453 eyes that underwent microincision vitrectomy surgery. All surgeries were performed by the same surgeon between 2003 and 2007 and were then retrospectively reviewed. Macular surgery represented 80% of the surgeries.

Minimal core pars plana vitrectomy was performed in the first 876 cases; complete PPV was done in the remainder. Retinal detachment secondary to retinal break occurred in 12 of the initial patients, but not in any subsequent patients.

"Retinal detachment can be avoided by performing complete vitrectomy for all surgical indications," Dr. Genovesi-Ebert said.

Other complications included IOP instability in the first postoperative week in 5.5% of cases, and 5% of cases required suture placement in at least one sclerotomy site. No intraoperative complications were attributable to the 25-gauge or 23-gauge instruments, and operating time was shortened, Dr. Genovesi-Ebert said.
