Abstract: An apparatus for evaluating the alignment of both eyes of a patient objectively in primary, secondary and tertiary gaze, and the Bielschowsky head tilt positions and to diagnose for phorias, tropias and intermittent tropias. The apparatus has a head restraint and a mounted fixation target in a spaced relationship to the head restraint and having adjustments for adjusting the target along three axis. Electronic shutters are used to occlude each eye during the testing. A camera is used for imaging the eye of a patient having his head in the head restraint with his eyes aligned with the target. The camera is mounted adjacent to the target on the xyz mount.
