Abstract

Three patients who experienced temporary visual loss after retrobulbar anesthesia with 2% lidocaine (Xylocaine) are described. Visual evoked potentials (VEPs) consistently increased in latency and decreased in amplitude. Abnormal VEPs such as these recorded for humans after retrobulbar anesthesia are, to our knowledge, reported here for the first time.
