视觉诱发电位(VEP)又称视觉诱发反应(VER),是一种无损伤性评价视功能的客观检查方法,是目前临床上唯一可以客观地检查视网膜神经节细胞以上神经功能的方法。关于原发性青光眼VEP 潜伏期可以延长,文献早有报导,但对于两种不同类型之青光眼VEP 潜伏期的检测有何特异性,至今尚未见报导。本研究采用棋盘格图象视诱发电位,对开角型青光眼和慢性闭角型青光眼,以及生理性大杯的VEP 潜伏期进行了检测,并与C/D 比值、定量视野等进行比较分析。 Visual evoked potential (VEP), also known as visual evoked response (VER), is a noninvasive objective assessment of visual function, and is currently the only method that can objectively examine neuronal function above the retinal ganglion cells. On the primary glaucoma, VEP latency can be extended, the literature has long been reported, but for the two different types of glaucoma, the detection of VEP lag has nothing to hitherto, no report yet. In this study, the visual evoked potentials were used to detect the VEP latencies of open-angle glaucoma and chronic angle-closure glaucoma, as well as the physiological cup. The VEP latency was compared with C / D ratio and quantitative field of view.
