| 摘 要： | 目的研究正常人不同刺激野图形翻转视觉诱发电位（pattern reversal visual evoked potentials，PRVEPs）的特点及其法医学应用价值。方法对30名（60眼）正常视功能的受试者分别进行全屏刺激野、中心刺激野及周边刺激野刺激，记录并分析PRVEPs的潜伏期与波幅。结果正常人左、右眼之间PRVEPs各波潜伏期及波幅差异无统计学意义。除中心刺激野PRVEPs中N1波的出现率为36．77％外，各波在不同刺激野PRVEPs的出现率为100％。全屏刺激野与周边刺激野N1波潜伏期差异有统计学意义，波幅差异无统计学意义。P1波潜伏期及波幅在三种不同刺激野PRVEPs中差异均有统计学意义。结论应用不同刺激野的PRVEPs．可对视网膜不同区域的功能状态进行客观评定，并可以用于对受试者是否存在伪装或夸大视野缺损的评定。 |

| Abstract: | Objective To study the character of the PRVEPs evoked by different stimulation fields in nor- mal-vision subjects and its value in forensic medicine. Methods The PRVEPs were evoked by full-field, central-field and peripheral-field respectively in 30 subjects (60 eyes) and the latency and amplitude of N1 and P1 were analyzed. Results There was no statistically significant difference in the latency and am- plitude of PRVEPs between right and left eyes. The appearance probability of all the waves was 100% at t... |
