Temporary amaurosis with persistent visual field defect following acute blood loss.
Visual loss and field defects commonly occur after acute blood loss. We present a case of bilateral permanent visual field defect in a 30-year-old man after a massive hemorrhage caused by large vessel injury during a right nephrectomy. His postoperative visual acuity decreased significantly, and his visual field showed peripheral constriction and inferior altitudinal field defect in both eyes. A year and a half after the operation, visual acuity recovered to the preoperative level, but the field did not show improvement. We advance that this is a possible result of extensive injury to the occipital area, excluding the corresponding area of the macula.
