Abstract:
Objective To analyze the characteristics of visual evoked potential (VEP) and the role of VEP in detecting posttraumatic optic nerve injury and evaluate the value of hyperxia liquid in treatment of posttraumatic optic nerve injury. Methods A total of 84 patients with optic nerve injury were divided into control group (n=47, received the general treatments) and treatment group (n=37, treated with hyperxia liquid on the basis of the general treatments) that were monitored regularly by VEP at days 1, 7, 14 and 21 respectively after treatment to analyze and compare latency, amplitudes, visual acuity and treatment result. Results After injury, abnormality of VEP occurred at days 1-7, reached the peak at days 7-14, and then markedly relieved at day 21. Compared with control group, degree of VEP abnormality was significantly lower (P
