闪光视觉诱发电位(F-VEP)是视觉诱发电位(VEP)中的早期形式,以后才逐步出现了以图形变换而诱发的图形视觉诱发电位(Pattern VEP,简称P-VEP)。由于F-VEP和P-VEP的刺激方式不同,它们各自所反映的信息也不同。F-VEP反映全部视神经的光敏感性,包括来自周边视网膜区粗的快相传入纤维。P-VEP主要反映提供中心视力的神经的功能状态,即反映来自黄斑部中心凹的细视神经纤维的功能。因此临床上用VEP来了解
The flash visual evoked potential (F-VEP) is an early form of visual evoked potential (VEP), and the pattern visual evoked potential (Pattern VEP, P-VEP for short) gradually evolved afterwards. Due to the different stimulus patterns of F-VEP and P-VEP, the information they reflect is different. F-VEP reflects the light sensitivity of all optic nerves, including fast-phase afferent fibers from the thick surrounding retinal area. P-VEP mainly reflects the functional state of nerves that provide central vision, that is, the function of the optic nerve fibers that reflect the fovea from the fovea. Therefore, the clinical use of VEP to understand
