摘　　要：以全视野亮背景及４５′视角的红色闪光作刺激，采用带中孔的角膜接触镜电极，记录了局部视网膜电图。测得２２只正常眼的黄斑中心对盲点区的局部ＥＲＧ振幅之比值为３．５４±１．３５，而３１只老年黄斑变性眼的比值是１．３９±０．５４，两者差异显著（Ｐ＜０．０１），两组全视野明适应ＥＲＧ间无意义，表明此法建立的局部ＥＲＧ记录技术对早期老年黄斑变性病人具有一定诊断价值。y means of the photopic ground of a Ganzfeld, a red flash of 45′ visual angle and a corneal contact lenswith central hole, the local electroretinogram(ERG)were recorded from 22 normal eyes and 31 eyes suffer-ing from AMD. The local ERG amplitude ratio of the macular versus optic disc was 3. 54±1. 35 and 1.39±0. 54 from normal and AMD eyes , respectively. There was statistically significant difference(P<0.01)between them , but was not on both the photopic ERGs, The results indicated that utilizing this recordingtechnique of the local ERG was shown to be some values for the early functional diagnosis of AMD.
