摘要 非动脉炎性前部缺血性视神经病变是50岁以上人群较常见的一类缺血性视神经病变,表现为突发无痛性视力下降、典型视野缺损、有特征性进展模式的视乳头水肿等。视乳头血循环短暂的无灌注或低灌注是其主要病因,但可能不是血栓栓塞性疾病。本病高发于高血压病、动脉粥样硬化、糖尿病、缺血性心脏病、高脂血症、代谢综合征等患者。视乳头小视杯是其发病的主要局部因素。夜间动脉低压是重要的发病促成因素。除眼底荧光素血管造影及视野检查外,光学相干断层扫描检查可随访、监测视乳头水肿变化。本病的视力预后与患眼缺血的严重程度和持续时间有关,早期大剂量糖皮质激素治疗有利于改善视力和视野。但目前对其病因、发病机制、临床特点及治疗等仍存在许多争论。
