Electro-oculography (EOG) is a technique for measuring the resting potential of the retina. The resulting signal is called the electro-oculogram. Monitoring eye movements is clinically important in diagnosis of diseases of the central nervous system.
Electro-oculography (EOG) is one method of obtaining such records which uses skin electrodes, and utilizes the anterior posterior polarization of the eye. The main applications are in ophthalmological diagnosis and in recording eye movements. Unlike the electroretinogram, the EOG does not represent the response to individual visual stimuli.
In the next post we will look at advantages and disadvantages of EOG.
