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

NCT03761641 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 24

Last updated 2024-10-15

No results posted yet for this study

Summary

This protocol is aimed at collecting oculomotor response data from a variety of brain injuries and impairments, and to secondarily evaluate the functionality and ease of use of the NeuroTriage device in the ED in patients with any presumed brain injury and/or impairment. For example, prior studies in adolescents with a concussion have shown that they tend to overshoot the pattern when asked to follow the movement of the lights in the binoculars

Conditions

Interventions

OTHER

Neurotriage

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.
