Intraoperative Perfluorocarbon Liquid Tamponade Technique for Treatment of Extensive Retinal Detachment Secondary to a Myopic Macular Hole.

Abstract

To report an intraoperative perfluorocarbon liquid (PFCL) tamponade technique in treating extensive retinal detachment secondary to a myopic macular hole (MH) through pars plana vitrectomy. The technique was applied in nine eyes with MH-RD extending two quadrants or more areas. The procedures for pars plana vitrectomy included: 1). thorough drainage of subretinal fluid through the MH with fluid-air exchange; 2). PFCL tamponade on the macular area for more than 10 minutes; and 3). repairing the MH after PFCL was removed. All nine eyes gained intraoperative retinal reattachment after PFCL tamponade for 22.22 ± 8.01 minutes and removal of PFCL. Procedures for MH closure included internal limiting membrane peeling in eight eyes, with internal limiting membrane free flap insertion (four eyes), internal limiting membrane inverted flap insertion (two eyes), or lens capsular flap transplantation (three eyes). All eyes received C3F8 tamponade. During 9.11 ± 3.89 months of follow-up, eight of the nine eyes (89%) achieved retinal reattachment and MH closure; one eye achieved anatomical success after reoperations. All eyes had vision improvement at the last follow-up. This new technique in pars plana vitrectomy may promote anatomical and functional recovery in the treatment of extensive retinal detachment secondary to a myopic MH.
