目的.目的：记录猴黄斑部局灶性视网膜电图（ERG）的明视负反应（PhNR），并研究其特性。用改进的红外眼底照相机记录了5只恒河猴的局灶性黄斑视网膜电图。研究了在100 scot cd/m（2）的稳定蓝色背景上呈现的不同刺激强度和持续时间对局灶性黄斑PhNR的影响。在玻璃体内注射河豚毒素（TTX）之前和之后，还记录了局灶性黄斑PhNR。当红色刺激点的亮度为
PURPOSE. To record the photopic negative response (PhNR) of the focal electroretinograms (ERGs) from the macula of monkeys and to study the properties of the focal macular PhNRs.METHODS. Focal macular ERGs were recorded from five rhesus monkeys using a modified infrared fundus camera, in which a red stimulus spot on a blue illuminated background were incorporated. The effects of different stimulus intensities and durations presented on a steady blue background of 100 scot cd/m(2) on the focal macular PhNRs were investigated. Focal macular PhNRs were also recorded before and after an intravitreous injection of tetrodotoxin (TTX).RESULTS. Focal ERG responses from a photocoagulated retinal site were recordable when the luminance of the red stimulus spot was
