Electrooculogram

Electrooculogram is an electrophysiological monitoring method to record electrical activity of the eyeball. It is a test to measure the electrical response of the light sensitive cells (rods and cones) and motor nerve components of the eye.

Its main applications are in ophthalmology and detection of eye disorders. There is a generation of a potential difference between the electrodes in correspondence with the motion of the eyeball. These potentials are very low magnitude bipolar signals, which are amplified by suitable bio potentials amplifiers after eliminating the shifting resting potential since these values vary continuously.
