多焦视网膜电图是国际上近十年逐渐发展起来的一种优于全视野和局部视网膜电图的新颖电生理记录技术,它将kemel分析法和电子计算机技术引入电生理信号记录中,较传统视网膜电图更为精细,分辨率更高。本文就多焦视网膜电图起源、记录原理和方法、波形特征、影响因素及其临床应用等作一综述,并提出了多焦视网膜电图尚需解决的问题。 Multifocal electroretinography (EMF) is a novel electrophysiological recording technique developed over the last decade in the world, which is superior to full-field and local electroretinograms. It introduces kemel analysis and computer technology into electrophysiological signal recording Traditional electroretinogram more sophisticated, higher resolution. This article reviews the origin, recording principle and method, waveform characteristics, influential factors and clinical application of multifocal electroretinogram. It also proposes some problems to be solved in multifocal electroretinography.
