Objective To study the response of the retinal neuronal adaptive system to changes of background illumination (BG) by measuring the oscillatory potentials (OPs) and the a- and b-waves of the electroretinogram (ERG) in different BG illuminations.

• 目的 观察不同强度背景光照明下视网膜电图 (electroretinogram,ERG)和振荡电位(oscillatory potentials,OPs)的变化 ,了解视网膜神经性调控机制对环境照明改变的反应。
