Abstract
A method and associated apparatus for validating testing procedure in objective ophthalmic eye testing is implemented for eye evaluation applications requiring subject compliance with eye fixation to a visual target. The method comprises the steps of: supplying a predetermined visual fixation target to the subject in a predetermined location with an automated ophthalmic eye testing device, wherein the testing procedure of the eye evaluation application requires the subject to fixate upon the visual fixation stimulus; tracking the subject's gaze during at least the supplying of the predetermined visual fixation stimulus to the subject throughout the testing procedure of the eye evaluation application with a video based eye tracking system; and validating the testing procedure by at least one of i) indicating to the clinician when the subject's gaze location differs from the predetermined visual fixation stimulus by an amount greater than a predetermined threshold amount, and ii) having the automated ophthalmic eye testing device repeat at least portions of the testing procedures when the subject's gaze location differs from the predetermined visual fixation stimulus by an amount gre…
