1. A system comprising:
an eye tracker having a camera, the eye tracker being configured and arranged to track an eye movement of a subject along a box trajectory having a top arm, a bottom arm and two side arms to obtain at least 100,000 samples of eye position over a period of 30 to 500 seconds;
a display configured to present a stimulus to the subject; and
a processor in communication with the eye tracker, the processor being configured and arranged to:
create a dataset of the eye movement as the subject responds to the stimulus;
generate a plot of the dataset corresponding to at least one of the top arm and the bottom arm, the plot reflecting a timecourse of eye position versus time; and
identify the presence of scanning vision by detecting one or more streaking vertical lines in the plot to indicate a deficit in a cranial nerve function.
