King Devick Test vs Developmental Eye Movement Test.

Two tests of eye movement skill that require calling out rows of numbers are currently in use in optometric practice. Our project is comparing the King Devick test validity in diagnosing oculomotor dysfunction to the Developmental Eye Movement Test (DEM) test. The
participants for the project consisted of thirty-two seventh and eighth graders at Morey Charter School in Winn, Michigan. Consent forms were sent out one week prior to the start of the data collection. The investigator administered each test randomly to each student during the study hall hour for ten to fifteen minutes. The King Devick test includes a demonstration card and three test cards with eight rows of five numbers read horizontally
simulating saccades that occur when reading The King Devick test is a diagnostic tool that assesses poor saccadic ability. However, it does not take into consideration that some individuals are slow in naming digits. In comparison, the DEM test consists of a vertical array of numbers and a horizontal array of numbers and can diagnose oculomotor dysfunction and
visual-verbal automatic skills by the amount of time each student takes to complete each task. We will be using McNemar's test to statistically analyze the results.
