Ischemic optic neuropathy (ION) is the term ascribed to optic nerve disease that is the result of a transient or permanent interruption of the blood supply to any portion of the optic nerve. Anterior ischemic optic neuropathy (AION) refers to ischemia of the optic nerve head, whereas posterior ischemic optic neuropathy (PION) indicates ischemia of the posterior optic nerve. IONs are primarily classified as arteritic ION and non-arteritic ION. A subset of ION that occurs around the time of surgery is termed peri-operative ION. These phenomena will be discussed as distinct entities.
缺血性视神经病变（ION）是指由于视神经任何部位的血液供应暂时或永久中断而导致的视神经疾病。前部缺血性视神经病变（AION）是指视神经乳头的缺血，而后部缺血性视神经病变（PION）则表示视神经后部的缺血。ION主要分为动脉炎性ION和非动脉炎性ION。在手术前后发生的ION子集被称为围手术期ION。这些现象将作为不同的实体进行讨论。
