摘　　要：目的探讨视神经损伤患者经颅视神经管减压治疗的临床疗效。方法回顾性分析经颅视神经管减压治疗的视神经损伤患者35例临床资料,3个月后复查视力及视觉诱发电位(VEP)检查。结果经颅神经管减压术后患者视力大部分改善;术前无光感患者术后视力恢复差;术后患者VEP的P100潜伏期延长、波幅降低,无光感患者波幅下降最明显。结论经颅神经管减压治疗有效,术前无光感患者手术效果差,术后VEP异常明显,VEP评价客观有效,与临床一致。Objective To explore the clinical efficacy of optic nerve injury by transcranial approach optic canal decompression.Methods The clinical data of 35 patients with optic nerve injuries treated by transcranial approach optic canal decompression were analyzed retrospectively.All of them were followed up 3 months later.Visual acuity and VEP test were examined.Results Visual acuity of most patients were improved by transcranial approaches optic canal decompression.Patients without light perception were poor recovery after operation.There was a significant delay in P100 latency and obvious delay in P100 amplitude of VEP after operation.The most obvious decline were patients without light perception about P100 amplitude of VEP.Conclusion Visual acuity of most patients were improved by transcranial approaches optic canal decompression.Patients without light perception were poor recovery.The VEP determination was obvious abnormal after operation.The VEP determination can accurately reflect the visual function and consistent with the clinical.
