摘    要:目的比较研究几种图形视觉诱发电位技术对视力推断的价值。方法取正常眼40只,分别测试其图形翻转视觉诱发电位、黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位,据此推算实验视力,分别与真实视力进行比较,同时各种方法进行彼此比较。结果黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位较之图形翻转视觉诱发电位能更为准确、方便、快捷地反映真实视力水平。结论黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位与图形翻转视觉诱发电位一样,可用于眼外伤的法医学鉴定。

关 键 词:图形翻转视觉诱发电位  扫描视觉诱发电位  实验视力  真实视力  法医学鉴定

Abstract:OBJECTIVE: To study and compare several measures of pattern visual evoked potential in measuring normal adults' real visual acuity. METHODS: Forty normal eyes were selected to test the pattern reversal visual evoked potential, black-white scanning pattern visual evoked potential, red-black scanning pattern visual evoked potential, respectively. Their experiment visual acuity was compared with their real visual acuity. RESULTS: The black-white scanning pattern visual evoked potential and the red-black sweep pattern visual evoked potential were more accurate, more convenient, and much faster in measuring real visual acuity than the pattern reversal visual evoked potential. CONCLUSION: Pattern reversal visual evoked potential, black-white scanning pattern visual evoked potential, and red-black scanning pattern visual evoked potential all can be used in forensic medical examination of eye injuries.
Keywords:pattern reversal visual evoked potential(PRVEP)  scanning pattern visual evoked potential(SPVEP)  experiment visual acuity  real visual acuity  forensic medical expertise
