The Horizontal Translational VOR
• Keeps the eyes still when the head moves laterally
(for example when you are looking out of the
window of the A train and trying to read the name of
the station past which you are traveling).
• Gain is dependent on viewing distance: during
translation a far object moves less on the retina
than a near object.
• The rotational VOR is not dependent upon viewing
distance.
• Most head movement evokes a combination of the
rotational (canal) and translation (otolith) VOR’s.
