光学相干断层扫描技术在非动脉炎性前部缺血性视神经病变中的诊断现状

非动脉炎性前部缺血性视神经病变(NA-AION)是一种中老年人常见急性致盲性眼病,临床表现为晨起或短暂休息后突发性的视力下降或视野缺损,视野缺损通常与生理盲点相连。目前,眼底和视野检查、荧光素眼底血管造影、视觉诱发电位是NA-AION常用的辅助检查手段。近年来,光学相干断层扫描技术(OCT)因具有无创、安全性高、分辨率高、扫描速度快、可三维重建和分层分析的特点已广泛用于NA-AION的诊疗中。本研究主要对OCT在NA-AION中的诊断现状及临床意义进行综述。

The situation of optical coherence tomography in the diagnosis of non-arteritic anterior ischemic optic neuropathy

Non-arteritic anterior ischemic optic neuropathy (NA-AION) is a common disease which caused blindness among the middle-aged and old people.The clinical manifestations of NA-AION include sudden blurred vision or defect of visual field which often happens in the early morning or after short break,and the defect of visual field usually connects to physiological blind spots.At present,the examinations of fundus and visual field,fundus fluorescein angiography (FFA) and visual evoked potential (VEP) are helpful in the diagnosis of NA-AION.In recent years,optical coherence tomography (OCT) has been widely used in the diagnosis and treatment of NA-AION due to its characteristics of non-invasiveness,higher safety and resolution,rapid scanning,three-dimensional reconstruction and stratification analysis.In this article,the diagnostic situation and clinical significance of OCT in NA-AION was reviewed.
