Objective To analyse the change in oscillatory potentials(OPs) of electroretinogram (ERG) and flash electroretinogram (F-ERG) in early diabetic retinopathy(DR). and so as to look for sensitive parameters to diagnose early DR.

• 目的 分析早期糖尿病视网膜病变 (DR)的闪光视网膜电图 (F- ERG)和视网膜电图震荡电位 (OPs)各参数的变化特点 ,寻找反映早期 DR的敏感指标。
