| 摘 要： | 作者采用双眼视差视觉诱发电位（VEP）记录了18名正常人和9名斜视患者（立体盲），结果正常人视觉刺激VEP P100振幅明显高于非视差刺激者；斜视患者视差刺激与非视差刺激VEP P100振幅差异无显著性；正常人视差刺激VEP P100振幅增加的幅度值（DSA-NDA）/NDA]明显高于斜视患者。

| Abstract: | We have utilized the binocular flat and stereoscopic pattern to record visual evoked potentials (VEP) in normal and strabismic subjects. The aim was to find an electrophysiological correlation with the degree of binocular interaction in these subjects.The perception as tridimensional or flat derived from the disparity obtained with polaroid filters placed in front of the eyes. In normal subjects, the results demonstrated a significant increase of VEP amplitude during tridimensional perception of the pattern. In strabismic subjects the electrophysiological response were not correlated with the binocular conditions. The findings in the present study suggest that the binocular disparity in VEP examination is a useful technique and a better objective index for evaluating stereoscopic function than the psychophysical technique.
