Head-Tilt Perfluorocarbon-Air Exchange Technique With Heads-Up Surgery for Giant Retinal Tear-Associated Retinal Detachments to Prevent Retinal Slippage Without Using Silicone Oil.

Abstract

To report the efficacy of the perfluorocarbon liquid-air exchange with a head tilt toward the area of the giant retinal tear (GRT) using the heads-up surgery system to prevent retinal slippage during vitrectomy for GRT-associated retinal detachments. Eyes with GRT-associated retinal detachments underwent vitrectomy using the heads-up surgery system and perfluorocarbon liquid-air exchange with a head tilt 45° toward the GRT to put the area of the tear in the most dependent position to drain fluid. This technique was evaluated to prevent retinal slippage. Five consecutive cases were evaluated. The mean GRT size was 174° (range, 90-240°) and the GRT was located temporally in two eyes, nasally in two eyes, and superiorly in one eye. The tamponade types were air (1 eye), sulfur hexafluoride (3 eyes), and perfluoropropane (1 eye). Our technique was feasible and the slippage did not occur in any eyes. Although the microscope needed to be tilted for optimal fundus visualization, heads-up surgery allowed surgeons to maintain ergonomic postures. Retinal reattachment was achieved with a single surgery in all eyes. The head-tilt perfluorocarbon liquid-air exchange with heads-up surgery is useful in preventing retinal slippage in eyes with GRT.
