Abstract:

A collaborative project between Naval Postgraduate School NPS, Veterans Affairs Palo Alto Health Care System VAPAHCS, Defense and Veterans Brain Injury Center DVBIC, and neuroFit Inc., was developed to 1 assess the efficacy of the Comprehensive Oculometric Behavioral Response Assessment COBRA as a screening method for mild-to-moderate Traumatic Brain Injury TBI in veterans, and 2 evaluate the usability of the neuroFit Oculometric Neurological Examination ONE device in military medical facilities. COBRA metrics used to characterize oculometric signs associated with TBI came from two published samples a 41-subject control sample and a 34-subject civilian TBI sample comprised of mild loss of consciousness LOC30 min, moderate 30 minLOC24 h, and severe LOC24 h TBIs. The control sample was compared to the eight-subject veteran TBI sample age range 2755 years 8 males from the VAPAHCS, comprised of mild n7 and moderate n1 TBI diagnoses and posttraumatic amnesia PTA n4. Results demonstrated a significant p .02 difference between the control and veteran TBI samples. COBRA metrics accurately detected TBIs at a rate of 77. Results indicate the COBRA method is viable for TBI screening in military medical facilities and may be suitable for diagnosing chronic visual problems related to mild and moderate TBI.
