In the field of eye tracking, greater accuracy or resolution in monitoring movement of the eye can be gained by digitizing the eye, and tracking the movement of a landmark with fixed size and a fixed location relative to the eye's local coordinate system. The edge of the iris can be used as such a fixed landmark. Through the location and or establishment of at least a portion of the outer edge of the iris and/or an iris center point, both large and small scale eye movements, including but not limited to micro-tremors, can be traced with a higher degree of accuracy. This will aid in the diagnosis of diseases, assessing state of consciousness, and defining brainstem death.

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 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 virtual reality portable device will allow more advanced usage for clinicians providing ongoing evaluation and treatment. 1.

Принадлежит: Neuro Kinetics Inc, University of Pittsburgh

A system and associated method for computerized rotational head impulse test (crHIT) to assess the semicircular canals of the human vestibular system clinically in patients with balance disorders. The system utilizes a rotary chair combined with a head mounted VOG system with head tracking sensors. The crHIT protocol uses the same physiologic principles as the known video head impulse test (vHIT). The crHIT utilizes whole-body rotation via the chair to yield a persistent controlled, repeatable, comfortable, reliable stimulus can be delivered while recording eye movements with video-oculogaphy.

Method and associated apparatus for detecting minor traumatic brain injury

Номер: US10743808B2
Автор: Alexander D Kiderman, James Z Cinberg
Принадлежит: Neuro Kinetics

Minor traumatic brain injury is detected by operating (a) an image generator for presenting a visual stimulus having a predetermined movement across a visual field of a subject and (b) a sensor device for monitoring fast eye movement of the subject while the subject views the stimulus. The sensor device generates a signal encoding the subject's eye position. A computer or microprocessor operatively connected to the sensor device is configured for determining a magnitude for the fast eye velocity component.
