摘要
目的探讨视觉诱发电位检查在急性球后视神经炎早期诊断、治疗、判断预后中应用的意义。方法对在2003年间在我院眼科住院治疗的急性球后视神经炎患者15例(26眼)行VEP检查。结果15例(26眼)中F-VEP检查6眼,6眼P1波峰潜时均延迟,振幅下降,其中图形熄灭2眼,异常率为100%。P-VEP检查20眼,有3眼振幅正常,16眼振幅下降,其中图形熄灭1眼,异常率为85%;有2眼峰潜时正常,17眼峰潜时延迟,1眼图形熄灭,异常率为90%。结论视觉诱发电位检查做为一种无创伤性,客观定量的视神经功能检查法,可大大提高急性球后视神经炎的早期诊断率,对其治疗亦有一定指导意义,同时在预后评价中也有很重要的临床价值。
AIM: To determine the significance of VEP's examination for acute retrobulbar neuritis.· METHODS: Fifteen cases (26 eyes) of acute retrobulbar neuritis accepted in our hospital in 2003 were examined.· RESULTS: Six eyes underwent F-VEP examination, and the P1 latency and amplitude were both unusual(100%). Twenty eyes underwent P-VEP examination, among which 6 eyes had unusual P amplitude (85%) and seventeen eyes had unusual P latency (90%).· CONCLUSIONS: Visual evoked potential examination is objective and quantitative with no wound. It can improve the early diagnose and is a good examination for prognosis evaluation.·
