Electroretinography (ERG)

An ERG is a device that measures the functional ability of the retina to respond to light; essentially testing to see if it is working properly. A sophisticated contact lens is placed on the eye and connected to a computer. A light is flashed at the eye and every time the light flashes, the retina should react and a wave that is captured on the computer. An ERG is used prior to cataract surgery to ensure that there is enough retinal function to warrant surgery as well as to make the diagnosis of different diseases of the retina.
