What is an electroretinogram (ERG)?ERG testing

An electroretinogram (ERG) is a recording of the electrical activity of the cells in the retina, the tissue at the back of the eye.  When bioelectrical changes occur in the retina, they are sent to the eye's surface. Using an electrode on the surface of the eye, an electroretinogram capture and record these changes.
