Pilot Study of NeuroTriage Device in Patients with Potential Brain Injury And/or Impairment

NeuroTriage binocular handset monitors pupil dynamics \& eye position with infrared cameras. Rubber non-allergenic ocular spacers contoured to eye sockets come in contact with the face \&cushion between the skin \& eyepiece. During pupil dilation tests, an LED briefly illuminates the pupil. The NeuroTriage system measures neurological pupil index, constriction velocity, \& dilation velocity. Total pupil dilation testing time is \< 1 minute. During saccade-tracking tests, patients direct their gaze towards dim LED targets selectable across the range of view. Visual targets involve center-out ocular motion or smooth pursuit following of illusory movement. The NeuroTriage system measures eye position \& movement velocity during these tests. Total saccade-tracking testing takes \< 3 minutes. Ocular measures are non-invasive, are done quickly and commonly used to measure neurological function.
