King-Devick test /kingdev′ik/ [Alan King and Steven Devick, American Doctors of Optometry] , a tool for evaluation of saccade, consisting of a series of charts of numbers. The charts become progressively more difficult to read in a flowing manner because of increasing space between the numbers. Both errors in reading and speed of reading are included in deriving a score. It is now a commonly used screening test for oculomotor, visual, and cognitive deficits. See also saccade.
