视觉诱发电位检查,是使视网膜经受视觉的适宜刺激一光线和图型的刺激以后,对大脑枕区皮层的电位活动进行记录和分析研究,借以客观地了解视功能损害时,从视网膜感觉细胞到视皮层中枢病变的主要部位和程度,从而达到较好地明确诊断,为治疗和了解病变发展过程提供更可靠的参数,也有助于判断病变的预后。虽然诱发电位技术的观测研究已有40年
Visual evoked potential test is to make the retina subjected to visual stimulation of a suitable light and pattern stimulation of the occipital cortical potential activity record and analysis of research to objectively understand the impairment of visual function from the retinal sensory cells to Visual cortex central lesion of the main parts and degree, so as to achieve a better definitive diagnosis, for the treatment and understanding of the lesion development process to provide more reliable parameters, but also help to determine the prognosis of the lesion. Although the evoked potential technology has been observed for 40 years
