非动脉炎性前部缺血性视神经病变（NAION）是50岁以上人群中最常见的急性视神经病变，也是成人致盲的仅次于青光眼的第二大常见病因。然而，其准确病因不明，现有观点认为其病因是多因素的。视盘解剖因素、全身性疾病、遗传因素、炎症因子等都可作为NAION的预警信号。近年来运用光学相干断层扫描技术（OCT）可有助于早期诊断此种疾病。通过OCT比较神经纤维层厚度和神经节细胞复合体的变化可了解病变发展的阶段。虽然没有特殊的治疗方法，但控制危险因素仍然是合理的、有益的方法。

Non-Arteritic ischemic optic neuropathy is one of the most common acute optic neuropathy in patients over the age of 50 and is the second most common cause of permanent optic nerve related visual loss in adults after glaucoma. Although the precise cause of NAION remains elusive, the etiology of NAION is believed to be multifactorial, the small size of the optic nerve head, systemic diseases, genetic factors, and inflammatory factors has been shown to play a role in the early period of NAION. Recently the use of optical coherence tomography (OCT) imaging can detect early stage of damage. The peripapillary retinal nerve fiber layer (RNFL) thickness and ganglion cell-inner plexiform layer analysis can help us learn about the stage of the disease. There is no clear scientific evidence for any specific therapy, however, there is general agreement that it is reasonable to control risk facotors.
