The oscillatory potentials (OPs) in electroretinogram (ERG) have clinical values in measuring retinal functions of the early stage of diabetic retinopathy. However, OPs have, until now, been evaluated as components of total ERG recorded with a full field stimulus over the entire retina. Therefore, little information could be obtained about the macular condition (diabetic retinopathy). Using focal stimuli, we successfully recorded OPs in the human macular region. We modified our previously reported system for recording local macular ERG under the fundus monitor with an infrared television fundus camera. We evaluated macular OPs with simultaneously recorded a- and b-waves in many patients with diabetic retinopathy. In some kinds of early diabetic maculopathy, the macular OPs were selectively reduced, leaving the a- and b-waves intact. The macular OPs can be a valuable indicator in assessing the macular function in diabetic maculopathy.
视网膜电图（ERG）中的振荡电位（OPs）在测量糖尿病视网膜病变早期的视网膜功能方面具有临床价值。然而，到目前为止，OPs一直被作为通过全视野刺激在整个视网膜上记录的总ERG的组成部分进行评估。因此，关于黄斑状况（糖尿病视网膜病变）的信息很少能获得。使用局部刺激，我们成功地在人类黄斑区域记录到了OPs。我们改进了之前报道的用于在眼底监测器下用红外电视眼底相机记录局部黄斑ERG的系统。我们在许多糖尿病视网膜病变患者中同时记录a波和b波来评估黄斑OPs。在某些早期糖尿病黄斑病变中，黄斑OPs会选择性降低，而a波和b波保持完整。黄斑OPs可以作为评估糖尿病黄斑病变中黄斑功能的一个有价值的指标。
