A MATHEMATICAL MODEL FOR THE DYNAMIC COUNTERROLLING OF THE HUMAN EYE.
Abstract
When the head is tilted to the side, the eyes rotate slightly in the opposite, compensatory, direction. This ocular counterrolling has been related to, and may provide a useful index of, otolith function. This report describes a technique for inducing and precisely recording ocular counterrolling. In normal subjects the eyes rotate as much as plus or minus 6 degrees depending on the amount, direction, and speed of head rotation around its X (fore and aft) axis. Counterrolling is maximum under static or low rotation-rate conditions. Labyrinthine-defective subjects exhibit little or no compensatory counterrolling. (Author)
