视神经挫伤%视觉诱发电位
視神經挫傷%視覺誘髮電位
시신경좌상%시각유발전위
Optic nerve contusion%Visual evoked potential
目的 探讨视觉诱发电位(VEP)的异常率对视神经挫伤诊断及预后估计.方法 对69例(69眼)单侧眼挫伤组进行视力检查及VEP检查,以自体健侧眼为对照组.分析两组间VEP P100波幅值及P100峰潜时值,记录单侧眼挫伤患者的伤眼、对侧眼及治疗后伤眼的VEP.结果 挫伤眼VEP P100波幅明显降低,P100峰潜时明显延长,挫伤眼各视力组VEP异常率明显高于对照组,挫伤眼矫正视力＜0.1者VEP异常更明显且预后差.结论 VEP是一种客观、定量、定位评定视神经功能的方法,是目前视神经病变最敏感、早期诊断、判断预后的客观检查方法,对视觉功能评价有重要的临床价值.
目的 探討視覺誘髮電位(VEP)的異常率對視神經挫傷診斷及預後估計.方法 對69例(69眼)單側眼挫傷組進行視力檢查及VEP檢查,以自體健側眼為對照組.分析兩組間VEP P100波幅值及P100峰潛時值,記錄單側眼挫傷患者的傷眼、對側眼及治療後傷眼的VEP.結果 挫傷眼VEP P100波幅明顯降低,P100峰潛時明顯延長,挫傷眼各視力組VEP異常率明顯高于對照組,挫傷眼矯正視力＜0.1者VEP異常更明顯且預後差.結論 VEP是一種客觀、定量、定位評定視神經功能的方法,是目前視神經病變最敏感、早期診斷、判斷預後的客觀檢查方法,對視覺功能評價有重要的臨床價值.

Objective To investigate the visual evoked potential abnormalities rate on the diagnosis and prognosis of optic nerve contusion.Methods Unilateral contusion of 69 for visual acuity and VEP examination to the contralateral eye as control self.Analysis of VEP P100 amplitude between the two groups and the time value of P100 peak latencies.Records of patients with unilateral contusion injury eyes,fellow eyes and eye injuries after treatment of visual evoked potentials.Results Contusion eye VEP P100 amplitude was significantly lower,P100 peak latency was significantly longer,the VEP abnormalities in visual acuity eye contusion group was significantly higher,Contusion eye vision correction ＜ 0.1 VEP abnormalities was more obvious and had poor prognosis.Conclusions VEP is an objective,quantitative assessment of optic nerve function positioning method,optic neuropathy is the most sensitive,early diagnosis,prognosis and objective examination methods,evaluation of visual function has important clinical value.
