Abstract
A device is for screening a person for CI and may include a binocular viewer, a display adjacent the binocular viewer, and a processor and associated memory cooperating with the display. The processor may be configured to display on the display a first visual stimulus and a second visual stimulus, cause, in alternating fashion, convergent movement and divergent movement in the first visual stimulus and the second visual stimulus along a visual stimulus path, determine respective centroid positions of the second eye and the first eye during the convergent and divergent movement of the first visual stimulus and the second visual stimulus, and calculate an IPD, and compare the IPD with the visual stimulus path to obtain a dynamic IPD, the dynamic IPD serving as an indicator for whether the person has CI.
