A 50-year-old man was referred for ophthalmoplegia that developed immediately after an 8.5-hour robotic cystectomy for small cell cancer of the bladder. After recovering from anesthesia in the postanesthesia care unit, he experienced headache, facial numbness, inability to open both his eyes, and inability to move both eyes in any direction.
He had a known enhancing central skull base lesion in sella turcica with compression of the optic chiasm and mild mass effect on the pons that was felt to be a pituitary macroadenoma (Figure). His baseline examination before the cystectomy showed visual acuity of 20/20 OU with intact extraocular movements and unremarkable confrontational fields, although a mild bitemporal hemianopia was seen on automated visual fields.
