Abstract

An apparatus for monitoring eye movement in a patient, includes a frame structured to be worn on the head of the patient. An infrared illumination device structured to illuminate an eye of the patient is supported by the frame. A camera structured to capture images of the eye when illuminated by the infrared illumination device is also supported by the frame. A number of sensors structured to generate data relating to one or more characteristics of the user or environment is further supported by the frame. The apparatus also includes a data storage device associated with the frame for recording the images and the data relating to one or more characteristics of the user or environment along with time information associated therewith. The apparatus is structured to generally not obstruct the patient'"'"'s view of their surroundings.

Claims

1. An apparatus for monitoring eye movement in a patient, the apparatus comprising:

a frame structured to be worn on the head of the patient;

an infrared illumination device supported by the frame, the infrared illumination device structured to illuminate an eye of the patient;

a camera supported by the frame, the camera structured to capture images of the eye when illuminated by the infrared illumination device;

a number of sensors supported by the frame, the number of sensors structured to generate data relating to one or more characteristics of the user or environment; and

a data storage device associated with the frame for recording the images and the data relating to one or more characteristics of the user or environment along with time information associated therewith,

wherein the apparatus is structured to generally not obstruct the patient'"'"'s view of their surroundings.

2. The apparatus according to claim 1, wherein the number of sensors comprises a motion sensor, the motion sensor being structured to generate data relating to a position of the head.

3. The apparatus according to claim 1, wherein the number of sensors comprises a luminance sensor for measuring data relating to ambient luminance.

4. The apparatus according to claim 1, wherein the number of sensors comprise:

a motion sensor, the motion sensor being structured to generate data relating to a position of the head; and

a luminance sensor, the luminance sensor being structured to measure data relating to ambient luminance.

5. The apparatus according to claim 1, wherein the camera is adapted to capture the images at a frame rate of at least 60 Hz.

6. The apparatus according to claim 1, wherein the frame comprises a main portion and a pair of side portions, wherein the main portion comprises a reflective member supported thereon, and wherein the camera is supported by one of the side portions and structured to capture images of the eye reflected by the reflective member.

7. The apparatus according to claim 1, wherein the data storage device is supported by the frame.

8. The apparatus according to claim 1,

wherein the frame comprises a transmitter supported thereon;

wherein the data storage device is separated a distance from the frame; and

wherein the transmitter is adapted to transmit, and the data storage device is adapted to receive and record, the images and the data relating to one or more characteristics of the user or environment along with time information associated therewith.

9. The apparatus according to claim 1, wherein the frame comprises another camera supported thereon, the another camera being structured to capture images of the patient'"'"'s surroundings.

11. A method of diagnosing episodic occurrences of dizziness or vertigo in a patient using the apparatus of claim 1, the method comprising:

providing the apparatus to the patient;

receiving data recorded by the patient using the apparatus; and

analyzing the data for the purpose of diagnosing a particular disorder or condition.

12. The method according to claim 11, wherein the data recorded comprises images of the eye and data describing ambient luminance at the time the images of the eye were recorded, and wherein analyzing the data comprises analyzing both the images of the eye and the data describing the ambient luminance.

13. The method according to claim 11, further comprising:

instructing the patient to don the apparatus when symptoms of at least one of dizziness and vertigo are experienced; and

instructing the patient to perform at least one of a number of activities once the apparatus is donned by the patient.

14. The method according to claim 13, wherein the number of activities comprise:

sitting upright in a lighted room;

sitting upright in a darkened room;

looking right, left, up, and down;

lying supine in a dimly lit environment; and

lying on the right and left side in a dimly lit environment.

10. An apparatus for monitoring eye movement in a patient, the apparatus comprising:

a frame structured to be worn on the head of the patient;

an infrared illumination device supported by the frame, the infrared illumination device structured to illuminate an eye of the patient;

a camera supported by the frame, the camera structured to capture images of the eye when illuminated by the infrared illumination device;

a luminance sensor supported by the frame, the luminance sensor structured to generate data relating to the measured ambient luminance; and

a data storage device associated with the frame for recording the images and data relating to one or more characteristics of the user or environment along with time information associated therewith.
