Unexplained postoperative retinal hemorrhage after 23-gauge sutureless vitrectomy

Abstract

Hisato Ohno, Kenji InoueInouye Eye Hospital, Tokyo, JapanAbstract: We report five cases of unexplained retinal hemorrhage after 23-gauge sutureless vitrectomy. A 23-gauge sutureless vitrectomy was performed for four cases of macular holes (MH) and one case of macular hole retinal detachment (MHRD). Retinal hemorrhages were observed on the first day after surgery and disappeared within several months without leaving any recognizable damage. We speculate that the retinal hemorrhages might have resulted from repeated collapse of the globe through a cannula under air perfusion, but other causes such as retinal vein congestion by face-down positioning are also possible.Keywords: retinal hemorrhage, vitrectomy, postoperative, macular hole, sutureless surgery
