A method of recording eye positions and movements.

1. Oculography in which electrodes placed on the skin adjacent to the eyes measure changes in standing potential between the front and back of the eyeball as the eyes move.
2. A sensitive electrical test for detection of retinal pigment epithelium dysfunction.
3. The study and interpretation of electroencephalograms made by moving the eyes a constant distance between two fixed points.
4. The recording and interpretation of the voltages which go with eye movements.

Eye-position voltages from electrodes placed on the skin near the eye are amplified and applied to a strip-chart recorder.

The process by which the position and movement of the eye is measured by the use of a light sensitive device: Ingrid's doctor had a specialist examine her eyes using a photosensor oculography procedure in order to make a better diagnosis of what was causing her to lose her vision.
