Definition & Meaning of "Electrooculography"

What is "electrooculography"?

Electrooculography (EOG) is a test used to track and measure eye movements by detecting electrical changes around the eyes. It examines how the eyes move in response to visual triggers or in different positions. By placing small sensors called electrodes around the eyes, EOG records these electrical signals produced by eye movements, which are then analyzed to evaluate the function of the eye muscles and the coordination of eye movements. This test helps diagnose issues with eye movement control, such as those caused by neurological conditions or eye disorders.
