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.
视力丧失和视野缺损在急性失血后很常见。我们报告一例30岁男性在右肾切除术期间因大血管损伤导致大量出血后出现双侧永久性视野缺损的病例。他术后视力显著下降，双眼视野显示周边收缩和下方视野缺损。术后一年半，视力恢复到术前水平，但视野没有改善。我们认为这可能是枕叶区域广泛损伤的结果，不包括黄斑相应区域。
