Monocular blindness due to central retinal artery occlusion in bipolar hemireplacement arthroplasty of the hip

Though rare, perioperative loss of vision after non-ocular surgeries is a disastrous complication. This has been reported after spine surgery or cardiopulmonary bypass surgery. We present an otherwise healthy 54-year-old man who underwent bipolar hemireplacement for a fractured neck of femur, and developed perioperative monocular visual loss due to central retinal artery occlusion, a complication hither to unrepor ted in hip replacement surgeries. The possible aetiological factors and the measures to prevent this complication are discussed.
