How is an Electroretinogram performed?

An electric sensor (electrode) is placed on each eye. The electrode measures the electrical task of the retina in accordance with mild. A gentle flashes, and the electrical response travels from the electrode to a TV-like display, where it can be considered and recorded.

Who invented Electroretinogram?

The first human ERG was once recorded in 1877 via Scottish chemist and physicist Sir James Dewar. James Dewar and John Gray McKendrick independently urged that the biological possible used to be from retina. In 1908, Einthoven and Jolly divided the ERG reaction into three elements: A-wave, B-wave, and C-wave.
