US 9,039,632 B2 · Quantitative, non-invasive, clinical diagnosis of traumatic brain injury using VOG device for neurologic optokinetic testing

Abstract

A portable VOG device is disclosed that will facilitate the effective and efficient screening for TBI in military personnel in forward deployed military settings or remote locations using minimally trained staff. This includes the establishment of a protocol including optokinetic testing that will provide cost effective pre-screening of military personnel prior to deployment to establish a baseline of brain function prior to possible future injury. The efficiency of the device will promote subsequent follow-up screening to assess the effectiveness of prescribed TBI treatment. Further protocols for diagnosis and rehabilitation applications using the same device will allow more advanced usage for clinicians providing ongoing evaluation and treatment.

Claims8

Dependent claims

A method of diagnosis of traumatic brain injury or concussion in a subject comprising the steps of:

A) providing a system including a stimulus generating portion and an eye tracking portion;
B) presenting visual stimulus to the subject via the stimulus generating portion, wherein the visual stimulus presented to the subject via the stimulus generating portion forms the optical target stimulus for at least one optokinetic test;
C) obtaining objective physiologic response of the subject in the form of reflexive ocular-motor responses of the subject's eyes from the eye tracking portion based upon each of the visual stimulus presented to the subject in each optokinetic test;
and
D) using the objective physiologic responses including the reflexive ocular-motor responses of the subject's eyes to the optical target stimulus of each optokinetic test to diagnose the presence of traumatic brain injury.

2 more elements

A method of diagnosis of traumatic brain injury in a subject comprising the steps of:

A) providing a head mounted stimulus generating eye tracking goggle unit coupled to the subject and generating a plurality of visual stimulus for the subject;
B) presenting the plurality of visual stimulus to the subject, wherein each visual stimulus is presented in the eye tracking unit, wherein each visual stimulus provides a target stimulus for a distinct visual based neurologic optokinetic test;
C) obtaining objective physiologic response of the subject from the eye tracking unit in the form of reflexive ocular-motor responses of the subiect's eyes based upon each of neurologic optokinetic test associated with each visual stimulus presented to the subject;
and
D) using the objective physiologic responses to the neurologic optokinetic tests including the reflexive ocular-motor responses of the subiect's eyes to the optical target stimulus to diagnose the presence of traumatic brain injury.
