A 2-year-old, castrated male, Scottish fold cat was referred to Veterinary Medical Teaching Hospital of Seoul National University (VMTH-SNU) for evaluation of acute bilateral blindness after general anesthesia. For dental prophylaxis in local animal hospital, general anesthesia had been induced with intravenous acepromazine and ketamine, and maintained with isoflurane after intubation. At VMTH-SNU on next day, complete blood count, electrolytes and serum chemistry values were within normal ranges. On neurologic examination, visual placing and postural reactions like as hopping, hemiwalking and wheelborrowing were reduced on right hindlimb. On ophthalmic examination, menace responses were absent on both eyes and pupillary light reflex (PLR) reduced on right eye, but other reflex and fundus were normal. Prednisolone (2 mg/kg sid for 3 days) was administrated orally and tapered. Visual placing was possible on 2nd day, and postural reactions were recovered on 4th day after dental prophylaxis. Based on the process and recovery, this case was considered as postoperative visual loss (POVL) after general anesthesia.
