Compensatory Eye Movements

Abstract

For several decades, the study of eye movements has been a source of valuable information to both scientists and clinicians. The singular value of studying eye movements stems from the fact that they are restricted to rotations in three planes and the eyeball offers very little inertia. This facilitates accurate measurement, for example using video eye recording in near infrared light, a prerequisite for quantitative analysis. Eye movements must continuously compensate for head movements so that the image of the world is held fairly steady on the retina, and thus appears clear and stationary.
