Electrooculography is the name of an electrical technique for recording movements of the eye.
Electrooculography is used to record an "electrooculogram" (or "EOG" for short) by attaching small electrodes to the skin around the eye. These may be attached at the inner- (closest to the nose) and outer- (closest to the nearest ear) corners of the eye.
The electrical potential between the two electrodes when the eye is at rest (i.e. not moving) gives useful information about the retina. When the eye moves the electrical potential between the electrodes changes and may be recorded continually over a period of time. This method can therefore be used to record and study how movements of the eye vary over a period of time.
There are various reasons for studying eye movements, some for clinical purposes and others for more general research into "Human Factors" and the psychology of visual perception and its many practical applications.
