CONTEXT: The occurrence of amaurosis during ophthalmic anesthesia is well known. The reason for this manifestation has not been studied. PURPOSE: To investigate the effect of sub-tenon's anesthesia on visual conduction in rabbit eyes. METHODS: Fifteen right eyes of 15 New Zealand albino rabbits were included. 2% lidocaine hydrochloride and 0.75% bupivacaine hydrochloride (1 ml, 1:1 mixture) was injected in the sub-tenon's space of 8 eyes while the control group (n = 7) was injected with 1 ml physiological saline. Flash visual evoked potentials (FVEP) were performed with Roland reti-scan system before and, 5 min, 15 min, and 5 days after injection. The natural pupillary diameter and minimal p..View full abstract
