视觉诱发电位是由大脑皮质忱区对视刺激发生的一簇电信息，它主要反应了从视网膜神经节细胞到视中枢间的生物电活动［１］。故它为视网膜神经节细胞到视中枢间的病变提供了一种客观的检查手段。现将我院１９９６年以来行视觉诱发电位（Ｐ－ＶＥＰ）检查的４４例病例进行总结分
Visual evoked potential is a cluster of electrical information generated by visual cortex in the cortical region of the cerebral cortex, which mainly reflects the bioelectric activity from the retinal ganglion cells to the optic chiasm [1]. So it provides an objective means of examination for the retinal ganglion cells to visual center lesions. Now our hospital since 1996, visual evoked potential (P-VEP) check the 44 cases were summarized
