A 70-year-old man presented with bilateral ischemic optic neuropathy. Workup revealed anemia that proved to be secondary to blood loss from an occult small bowel sarcoma. Ischemic optic neuropathy is an uncommon complication of gastrointestinal hemorrhage. It is important to recognize the association of visual loss and severe blood loss when they occur concurrently, so that proper treatment may be promptly instituted.
一名70岁男性出现双侧缺血性视神经病变。检查发现贫血，结果证明是由隐匿性小肠肉瘤失血所致。缺血性视神经病变是胃肠道出血的一种罕见并发症。当视力丧失和严重失血同时出现时，认识到它们之间的关联很重要，以便能及时采取恰当的治疗措施。
