To study and compare several measures of pattern visual evoked potential in measuring normal adults' real visual acuity.
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.
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.
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.
研究并比较几种图形视觉诱发电位测量正常成年人真实视力的方法。
选取40只正常眼睛，分别测试图形翻转视觉诱发电位、黑白扫描图形视觉诱发电位、红黑扫描图形视觉诱发电位。将其实验视力与真实视力进行比较。
在测量真实视力方面，黑白扫描图形视觉诱发电位和红黑扫描图形视觉诱发电位比图形翻转视觉诱发电位更准确、更便捷、速度更快。
图形翻转视觉诱发电位、黑白扫描图形视觉诱发电位和红黑扫描图形视觉诱发电位均可用于眼外伤的法医学鉴定。
