视网膜电流图的振荡电位(Oscillatory Potentials简称OPs),反映了视网膜血液循环的状况。在某些视网膜血管性疾病,特别是糖尿病性视网膜病变(以下简称DR),OPs振幅可能出现选择性的下降或熄灭,而ERG的a、b波振幅仍旧正常。OPs的严重减少与视网膜循环障碍间,看来存在某种关联。有关OPs的研究,国外许多学者已作了很多的工作,国内尚未见报道,现综述于下。 Oscillator potential (Oscillatory Potentials referred to as OPs), reflecting the status of retinal blood circulation. In some retinal vascular diseases, especially diabetic retinopathy (hereinafter referred to as DR), OPs amplitude may be selectively decreased or extinguished, while ERG a, b wave amplitude remains normal. There seems to be some correlation between a serious decrease in OPs and retinal circulation disorders. For the study of OPs, many foreign scholars have done a lot of work, not yet reported in China, are summarized below.
