视网膜电图诊断早期糖尿病视网膜病变

视网膜电图是一项评价视网膜功能的客观检查，适用于评价多种眼科疾病的视网膜功能情况。近年研究发现，在早期糖尿病患者中，视网膜电图能够发现先于眼底视网膜形态学改变的功能变化，这一点为糖尿病视网膜病变的病理机制研究、早期诊断、以及预后评估提供了新思路，进而可能为治疗糖尿病视网膜病变提供新途径。我们就运用视网膜电图诊断早期糖尿病视网膜病变进行综述。

Research of using electroretinogram for diagnosising early diabetic retinopathy

Electroretinogram(ERG)is an objective examination in evaluating retinal function, which is also suitable to evaluate retinal function of multiple ophthalmic diseases. In recent years, studies have found that ERG can find functional changes prior to morphological changes of fundus examination in early diabetics, which provides a new way for researches of pathological mechanism, early diagnosis and prognosis evaluation for diabetic retinopathy, and then also provides a new therapy for diabetic retinopathy. In this paper, using ERG in the diagnosis of early diabetic retinopathy was reviewed.
