Abstract: A neurological screening device and method for assessing brain dysfunction of a subject including a projection apparatus configured to project an image onto retinas of a subject, detectors configured to capture light reflected from the retinas, the reflected light indicating a fixation of the eyes, a controller configured to generate baseline cognitive performance data based at least in part on a presence or absence of fixation, cause output of a plurality of assessment images on displays of the neurological screening device, the plurality of assessment images corresponding to a cognitive assessment configured to stress the frontal lobe of the subject, generate stressed cognitive performance data based at least in part on a presence or absence of fixation during the cognitive assessment, and determine brain dysfunction of the subject based at least in part on the baseline cognitive performance data and the stressed cognitive performance data.

Abstract: An apparatus and method for ophthalmic neural scanning including a projection apparatus configured to project a projected image onto one or more retinas of one or more eyes of a subject, one or more photodetectors disposed conjugate to the one or more retinas, the one or more photodetectors being configured to capture a reflected image reflected from the one or more retinas in response to the projected image, the reflected image including information indicating fixation of the one or more eyes, and an image capture device disposed conjugate to one or more corneas of the one or more eyes of the subject and configured to capture a diagnostic image including one or more pupils of the one or more eyes when the one or more pupils are illuminated by retroreflected light from the one or more retinas in response to the projected image.

Abstract: A method and apparatus for fixation measurement includes projecting, by an image projector, a stimulus onto one or more eyes of a patient via a beam splitter, and capturing, by one or more image sensing devices disposed conjugate to the one or more eyes, a reflected image including light reflected from the one or more eyes in response to the stimulus, the reflected image including information indicating the fixation of the one or more eyes.

Abstract: A method and apparatus for fixation measurement includes rotating a first reflector comprising a diffraction component about a rotation axis, the first reflector being configured to reflect light received from a light source onto a second reflector via the diffraction component and reflect light received from the second reflector via the diffraction component and capturing light which is reflected by the second reflector and subsequently reflected by the first reflector with one or more photodetectors.

Abstract: A method and apparatus for fixation measurement includes projecting, by a projection apparatus, a target image onto one or more eyes of a patient and capturing, by one or more image sensing devices disposed conjugate to the one or more eyes, a reflected image reflected from the one or more eyes in response to the target image, wherein the reflected image includes information indicating the fixation of the one or more eyes.
