Electroretinography (ERG) is a test that measures the electrical activity of the retina, the light-sensitive layer at the back of the eye. During the test, small sensors called electrodes are placed on the skin around the eyes or on the cornea, the clear, outer layer at the front of the eye, to detect the electrical responses produced by the retina when exposed to light. This helps doctors evaluate the function of the retina and diagnose conditions that affect vision, such as retinal diseases or disorders.Electroretinography (ERG) is a test that measures the electrical activity of the retina, the light-sensitive layer at the back of the eye.
