Abstract

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.
