Abstract
We propose in this work to report a case of perioperative posterior ischemic optic neuropathy, after a cardiac surgery. This is a 45-year-old patient, operated for Coronary Angioplasty and Stenting. 24h after the surgery he noticed a bilateral loss of vision. Examination of the both eyes revealed visual acuity decreased to no light perception, absent pupillary light reflexes and normal fundus. The neurological examinationis normal, macular OCT and cerebral magnetic imaging were normal. Visual evoked potentials were absent confirming the diagnosis of right retrobulbar optic neuropathy. The evolution was marked by no improvement of vision and the development of optic nerve atrophy. Perioperative posterior ischemic optic neuropathy during cataract surgery is an extremely rare incident. Posterior ischemic optic neuropathy is an uncommon complication Its physiopathology is multifactorial and dominated by hypotension and anemia. Its prognosis is bad and visual recovery is generally poor.
