Ischaemic optic neuropathy is a rare but serious complication post cardiopulmonary bypass in cardiac surgery patients. It presents with visual loss either unilaterally or bilaterally, and it can be anterior or posterior in type depending on the segment of the optic nerve involved. In non-ocular surgery patients, the most common type is called non-arteritic ischaemic optic neuropathy. We report a case of bilateral non-arteritic ischaemic optic neuropathy following coronary artery bypass grafting and mitral valve surgeries and review the published literature for the aetiology, management and prognosis of this rare complication.
缺血性视神经病变是心脏手术患者体外循环后一种罕见但严重的并发症。其表现为单侧或双侧视力丧失，根据受累视神经节段的不同，可分为前部或后部缺血性视神经病变。在非眼科手术患者中，最常见的类型称为非动脉炎性缺血性视神经病变。我们报告一例冠状动脉搭桥术和二尖瓣置换术后双侧非动脉炎性缺血性视神经病变的病例，并回顾已发表文献中关于这种罕见并发症的病因、治疗及预后情况。
