  • Patent number: 9730583
    Abstract: A video oculography (VOG) system for calculation and display of Corrective Secondary Saccades Analysis is disclosed and utilized in a method for Objective Diagnostics of Internuclear Opthalmopligia, Ocular Lateral Pulsion, Progressive Supernuclear Palsy and Glissades. The method comprises the steps of using a VOG system to calculate corrective saccades. The VOG based system is configured to collect eye images of the patient in excess of 60 hz and configured to resolve eye movements smaller than at least 3 degrees of motion and collects eye movement data wherein at least one fixation target is presented to the subject in a defined position configured to yield a voluntary saccadic eye response from at least one eye of the patient. The latency, amplitude, accuracy and velocity of each respective corrective saccade and totals latency and accuracy are calculated.

  • Patent number: 9655515
    Abstract: 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.

  • Publication number: 20160270711
    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 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.

  • Patent number: 9101296
    Abstract: A goggle based light-weight VOG/EOG system includes at least one digital camera connected to and powered by a laptop computer through a firewire connection. The EOG system is incorporated directly into a goggle base. The digital camera may digitally center the pupil in both the X and Y directions. A calibration mechanism may be incorporated onto the goggle base. The VOG system may track and record 3-D movement of the eye, track pupil dilation, head position and goggle slippage. An animated eye display provides data in a more meaningful fashion. The VOG system is a modular design whereby the same goggle frame or base is used to build a variety of digital camera VOG systems.

  • Publication number: 20150018709
    Abstract: 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.
