摘　　要：目的记录并观察非动脉炎性前部缺血性视神经病变(NAION)患者黄斑下脉络膜厚度的临床特征。方法回顾性病例对照研究。研究组NAION患者17例(17只眼),对照组正常人14例(14只眼)。相干光断层扫描(OCT)的加强深度成像模式(EDI)扫描黄斑区并测量5 mm区域内黄斑下脉络膜厚度。结果 NAION患者黄斑中心凹下脉络膜厚度明显薄于对照组(P<0.05),黄斑下脉络膜厚度与NAION病情之间存在显著相关性。结论 NAION患者脉络膜厚度明显薄于正常人,黄斑中心凹下脉络膜厚度可以作为用于有效诊断NAION的临床指标。Objective To record and detect the clinical alterations of choroidal thickness in patients with non-arteritic anterior ischemia optic neuropathy（ NAION）. Methods This was a retrospective case control study. 17 NAION eyes and 14 normal eyes（ control group） were studied. Choroidal thickness was measured with enhanced-depth imaging by spectral-domain optical coherence tomography. Results NAION eyes showed thinner subfoveal choroidal thickness（ P〈0. 05） when compared to control eyes. Thinner subfoveal choroidal thickness was associated with the diagnosis of NAION.Conclusions Choroidal thickness was obviously thinner in NAION patients than in normal subjects,and the subfoveal choroidal thickness could be used as a clinical index for the diagnosis of NAION.
