Abstract: An apparatus for measuring eye movement (ocular pursuit) of a subject by moving a target along an arcuate member disposed ahead of the subject is described, wherein the target is moved in a channel formed in the arcuate member, and a clamp adapted for moving with the target for locating the position of the target along the arcuate member, thereby reducing unintended further movement thereof once the measurement has been completed.

Abstract: An improvement is described in regard to a target which is useful in a process for measuring eye movement of a subject. The target includes a support member with a flat or planar bottom surface which can rest upon the top edge of the arcuate member which is used in measuring eye movement. The target can be easily moved along the arcuate member in a smooth and steady manner, with the support member resting on the arcuate member.

Abstract: A unique technical process which must be taught is provided for quickly, simply, objectively and accurately measuring an individual's ocular tracking ability. The technique includes a process for measuring only the smooth movement of the eye, and both eyes together, in a neurologically oriented eye examination for educational diagnosis and evaluation. As a result of the examination one may prescribe motor-perceptual training. The most simple economical instrument providing instantaneously usable scores is described which is an improvement for this useful purpose and it overcomes the disadvantages of the prior art.
