摘要
目的利用视觉诱发电位（VEP）判断严重视神经损伤的预后。方法回顾分析30例严重视神经损伤的VEP检测及临床治疗资料，按伤后视力分为A、B两组，统计学分析两组VEP变化及治疗效果。结果闪光视诱发电位（FVEP）是两组差异显著的指标，A、B组FVEP平均波幅下降率分别为79％、43％，治疗后有效率分别为13％、80％，两组间存在显著差异（P＜0．01）。结论FVEP对于判断严重视神经损伤的视力预后具有重要价值。
Objective To evaluate the prognosis of patients with serious optic nerve injury by visual evoked potentials(VEP). Methods The VEP data and clinical therapy of 30 cases with serious optic nerve injury were re viewed.Accrding to the visual acuity of the traumatized eyes, the pa tients were divided into group A and B.The change of VEP was analyzed statistically, and the effects of two treatments were compared.Results The amplitude of VEP droped by 79% in group A and 43% in group B.Visual acuity improed in 13% of patients in group A and 80% in group B.There was significant difference between two groups (P < 0.01).Conclusion FVEP was an valuable index to evaluate the visual prognosis after serious optic nerve injury.
