摘　　要：目的:观察增生型糖尿病视网膜病变(proliferative diabetic retinopathy,PDR)的多焦视网膜电图(multifocal electroreti-nogram,mf-ERG)的图像特征及临床意义。方法:对临床确诊的PDR患者40例44眼(PDR组)和正常对照组40例40眼进行mf-ERG检查,并对所得数据进行统计分析。结果:PDR患者组mf-ERG1～5环的反应密度均低于正常对照组,且有显著性差异,N1波潜伏期在4环、P1波潜伏期在2～5环与正常对照组相比显著延长。结论:Mf-ERG可有效地评价PDR患者视网膜的功能。AIM：To observe the characteristics of the images of multifocal electroretinogram（mf-ERG） performed on the patients with severe proliferative diabetic retinopathy（PDR）and its clinical significance.METHODS：Forty PDR patients（44 eyes） and forty normal control subjects（40 eyes） were tested with mf-ERG.The data were processed with software SPSS 13.0.RESULTS：mf-ERG showed the response densities of ring 1-ring 5 areas in PDR were significantly decreased while the latencies of ring 4 of N1 wave and the latencies of ring 2,ring 3,ring 4 and ring 5 of P1 wave were significantly prolonged with normal control group.CONCLUSION：mf-ERG can provide more information to evaluate the retina function effectively in PDR.
