Unilateral visual loss after spine surgery in the prone position for extradural haematoma in a healthy young man

This case reports a patient who developed central retinal artery occlusion following spinal surgery in the prone position. When placed in this position, especially as a result of malposition of the head, the patient may develop external compression of the eye which leads to central retinal artery occlusion. Therefore, a special precaution must be given for adequate eye protection during prolonged prone-positioned spine surgery.
