多焦视网膜电图是视觉电生理学的一项重要新进展 ,它应用先进的数字信号处理和电子计算机技术 ,可在较短时间内同时测量几十度视野范围内几十到几百个区域的局部视网膜电图 ,并计算各局部反应的一阶反应和二阶反应 ,根据各反应的参数分别了解视网膜内外层对应于视野各部位的功能 ,目前该技术已在临床上得到应用。 Multifocal electroretinography is an important new advance in visual electrophysiology that uses advanced digital signal processing and computer technology to simultaneously measure dozens to hundreds of fields in dozens of degrees in a short period of time According to the parameters of each reaction, the function of inner and outer layers of retina corresponding to each part of the visual field is separately understood. At present, the technique has been applied clinically.
