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
