Flash Electroretinography

Flash Electroretinography (ERG) is a diagnostic test that measures the electrical responses of the retina—the light-sensitive layer at the back of your eye—to flashes of light. During the test, small electrodes are placed on or near the eye to record how well the retina reacts. This helps doctors assess the function of different retinal cells, identify various eye conditions, and evaluate overall retinal health. The procedure is quick, non-invasive, and provides valuable information about how your eyes process light signals, aiding in the diagnosis of retinal diseases.
