努力提高非动脉炎性前部缺血性视神经病变的诊断和治疗水平

非动脉炎性前部缺血性视神经病变(NAION)以视力突然减退,与生理盲点相连的扇形或半侧视野缺损和视盘水肿为临床特征;其发病与缺血性心脑血管疾病有基本相同的病理基础和临床过程.如何正确认识其临床特征、全面理解局部和全身因素在NAION发病中的作用;加强与相关学科专业的配合,在改善NAION患者眼部缺血状态的同时,预防患者更严重的心脑血管事件发生都是亟待解决的问题.

Diagnosis and treatment of non-arteritic anterior ischemic optic neuropathy

The characteristics of non-arteritic anterior ischemic optic neuropathy (NAION) include sudden decline of visual acuity, sector-shaped visual field defect connected with the physiological blind spot or hemi-visual field defect, and optic disc edema. Early angiographic abnormalities of optic disc and peripapillary choroidal circulation are important cues for the diagnosis. Angiography combined with visual field test can make the diagnosis more accurate. The pathological mechanism and process of NAION and ischemic cardiovascular/cerebrovascular disease are essentially the same. There are several critical issues in this field we need focus on, including strengthening the cooperation with relevant professional disciplines; improving the ocular ischemia through drugs, intervention and other means; preventing more serious cardiovascular events and intervening in a number of high-risk populations to reduce the incidence of AION.
