视神经挫伤60例的视觉诱发电位分析

Analysis of visual evoked potential of 60 patients with optic nerve contusion

目的:探讨视觉诱发电位(visual evoked potential,VEP)对视神经挫伤临床诊断的作用。方法:对我科近两年临床诊断为视神经挫伤的患者60例(72眼)进行VEP检查。结果:P-VEP正常30眼;P100波潜伏时延迟22眼;P-VEP无波,F-VEP振幅降低12眼;P-VEP、F-VEP均无波8眼。结论:VEP检查是视神经挫伤的客观检查手段之一。

AIM： To evaluate the effect of visual evoked potential （VEP） on the diagnosis of optic nerve contusion. METHODS： The VEP check was performed on 60 patients who suffered from optic nerve contusion with Bravo Visual electrophysiological System. RESULTS： Thirty eyes showed P-VEP normal, 22 eyes showed P100 wave latency delay, 12 eyes showed no signals in P-VEP and decreased amplitude in F-VEP, and 8 eyes showed no any signals. CONCLUSION： VEP is one of the objective methods to detect optic nerve contusion.
