Clinical Application of Multimodality Visual Evoked Potentials

多通道视觉弯曲电位包括视网膜电图（ERG）、视觉弯曲电位（VEP）和事件相关电位（ERP）。我们从1995年至1996年进行了以下三个项目的研究：1. Ganzfeld ERG：正常波形和临床应用。在暗适应和光适应条件下，使用非侵入性技术记录Ganzfild ERG。视网膜电图的正常存活数据不可靠。2.图形反转ERG和VEP的规范性研究及临床应用。研究了年龄对ERG振幅、ERG/VEP潜伏期的影响。3.视觉事件相关电位：规范性数据及临床应用：N200/P300分别检测Cz/Pz和N100/P100检测Oz。该技术已应用于帕金森病、脊髓小脑变性、阿尔茨海默病、中风等疾病，其异常表现为振幅降低或潜伏期延迟，与认知功能障碍相关。

Multi modality Visual Rooked Potentials consist of Electioretinograms (ERG), Visual cooked potentials (VEP) , and Event-related potentials (ERP). We have in vestigated from 1995 to 1996, on the following three projects.1.Ganzfeld ERG : Normal waveforms and Clinical Applications. Ganzfild ERG was recorded during dark-adapted and light-adapted conditions, using non-invasive techniques. Normalive data of the ERG was lotablishid. The ERG was applied to PM retinopathy patients.2.Pattern-reversal ERG and VEP : Normative Data and Clinical Application. We have studies the effect of aging on ERG amplitude, ERG/VEP latencils. The tests were applied to multiple sclerosis.3.Visual Event-related potentials : Normative Data and Clinical Applications.N200/P300 were detected from Cz/Pz and N100/P100 from Oz. The technique was applied to Parkinson's disease, Spino cerebella degeneration, Alzheimen's disease, Stroke etc, It's abnormality conisted of amplitude reduction or latency delay, correlating with cognitioe dysfunctions.
