视觉诱发电位检查是眼科的主要检测手段之一,在眼科临床和基础研究中起着重要作用,但也存在局限性。由于传统的视觉诱发电位是以闪光或图形刺激整个视网膜,测得的结果是总和反应,对微小病灶不敏感,也不能对病灶进行定位。局部视觉诱发电位由于信噪比低,需要多次累计,且需对多部 Visual evoked potential test is one of the main methods of ophthalmology, plays an important role in the clinical and basic research of ophthalmology, but there are also limitations. Since traditional visual evoked potentials stimulate the entire retina with flash or graphics, the result is a summed response that is insensitive to minor lesions and does not allow localization of the lesion. Local visual evoked potential due to low signal-to-noise ratio, need to be accumulated several times, and the need for more
