Abstract
A method of measuring and analyzing an ocular response in a subject comprising the steps of: Providing a video oculography based system for the subject with the system configured to collect eye images in excess of 60 hz and configured to resolve eye movements smaller than at least 3 degrees of motion; Collecting eye data with the video oculography based system wherein at least one stimulus is presented to only one eye of the subject and configured to yield a pupil eye response from at least one eye of the subject; Calculating pupilometry measurements from the eye data, wherein the pupil measurements are calculated independently for the subject's left and right eyes for each stimulus presented to the subject, and wherein comparative left and right pupilometry measurements from the eye data are calculated; analyzing a subject's ocular response based upon at least one of the calculated pupilometry measurements.
