非动脉炎性缺血性视神经病变的病因研究进展

Advances in etiological study of non-arterial inflammatory ischemic optic neuropathy （NAION）

非动脉炎性前部缺血性视神经病变（NAION）是中老年常见的眼部疾病，系视神经局部缺血导致视盘水肿，进而引发视神经萎缩。近年来的研究多从NAION的危险因素人手进行早期干预，从而保护视神经及视网膜细胞免于死亡。本文综述NAION近年来危险因素及病因等方面的研究进展。

Non-arterial Inflammatory ischemic optic neuropathy （NAION） is a common ocular disease in middle and old ages. Symptoms of optic nerve dysfunction in NAION are caused by cerebral ischemia, which leads to optic atrophy. Recent studies have focused on the early interventions targeting NAION＇s risk factors to protect the optic nerve and retinal ganglion cells. This article reviews recent progress in studies on the etiology and risk factors of NAION and potential therapies that may help to preserve optic nerve function in NAION.
