Electrooculography (EOG) is a technique for measuring the corneo-retinal standing potential that exists between the front and the back of the human eye.

Primary applications are in ophthalmological diagnosis and in recording eye movements.

Unlike the electroretinogram, the EOG does not measure response to individual visual stimuli.

In 1951 Elwin Marg described and named electrooculogram for a technique of measuring the resting potential of the retina in the human eye.

In practice, the measurement is similar to eye movement recordings (see above).
