摘　　要：检测了正常人１３８只眼的图像视觉诱发电位．结果表明，图像视觉诱发电位ＡＮ７５和ＡＰ１００随年龄增大而明显变小，ＬＮ７５和ＬＰ１００随年龄增大而不同程度地缩短．图像视觉诱发电位ＡＮ７５和ＡＰ１００与空间频率密切相关，用大、中、小３种方式剌激时随方格的变小而明显变大．在Ｎ７５和Ｐ１００的振幅和潜伏期４项指标中，潜伏期的变异较小，而振幅的变异较大．eyes’patten visual evoked potential(P VEP) of normal persons were measured.The results indicate that P VEP AN 75 and AP 100 become smaller obviously with age.LN 75 and LP 100 become shorter at different degrees with age.P VEP AN 75 and AP 100 have close relationship with spacious frequency.If being stimulated with big,middle and small kinds of checks,they will become big obviously with ohecks' being small.In the four indexes of amplitude and incubation period of wave N 75 and wave P 100 ,the variation of incubation period is comparatively small,and the one of amplitude is just opposite.
