摘　　要：对 30例交通肇事眼损伤鉴定及其VEP检查结果进行回顾性分析 ,旨在探讨交通肇事眼损伤鉴定的特征 ;结果表明 :与普通伤害案件相比 ,(1)交通肇事眼损伤鉴定时合并颅脑损伤 (83% )及多颅神经损伤 (53% )的比例较高 ;导致复视及眼球运动受限 (30 % )的情况较多 ;视神经损伤 (2 0 % )及眶壁骨折 (2 0 % )的发生率较高 ;鉴定时应注重这些方面的检查。 (2 )交通肇事眼损伤鉴定当事人主诉双眼视力下降 (53% )的比例较高 ,雾视法进行伪盲试验受到限制 ,VEP检查显得更为主要。VEP检查是确证视神经损伤的良好方法 ,不同程度的视功能障碍其VEP表现为波形熄灭、波形离散、波幅降低、潜伏期延长不等。另一方面 ,交通肇事后弥漫性脑组织损伤也在眼底及VEP上有一定表现。In order to investigate the characteristics of forensic medical appraisals of ocular trauma caused by traffic accidents, Visual Evoked Potential examinations were performed in 30 cases and the results were analyzed It was found that, compared with 30 cases of ocular trauma caused by ordinary injuries,(1)the proportion of craniocerebral injuries (83%) and cranial nerve injuries (53%) was much higher, so were the proportion of diplopia (30%), optic never injuries (20%), and orbital wall fracture (20%) (2) because victims always claimed that their visual acuity was reduced by traffic accidents, it was difficult to identify simulated lower visual acuity by ordinary method, and VEP examination was often used Different degrees of visual functional disorders showed different patterns in VEP, such as no VEP wave, lowed P1 wave amplitude, delayed P1 period, and so on
