Electrooculograph

Definition

An ophthalmic device used to record the gradual changes in the electric potential between the retina and the cornea during ocular motion in response to visual stimuli. This recorder is used with surface electrodes placed on the lateral canthi of each eye and an amplifier that boosts the bioelectrical potential. Some are compatible with a personal computer (PC) for waveform storage and analysis. It is used to help diagnosis in certain forms of retinal diseases, e.g., assessing light and dark adaptation of the eye. It may have additional capability for recording the short, fast movements of the eyes made during reading and sleep.
