Recording Session

Within less than 1 minute, the dizzy patient will be able to use the Vertigo Recording Goggles to obtain accurate recordings of their eye movements in each of the four Dix-Hallpike positions.

Recording Session

During an attack of vertigo, a patient will be able to use the DizzyDoctor Vertigo Recording Goggles (VRG) to obtain recordings of their eye movements in the four proper Dix-Hallpike testing positions. The DizzyDoctor App is designed to not only accurately walk the patient through each position by using step-by-step voice commands, but it also utilizes the smart phone’s internal gyroscope to detect and verify the patient’s head is accurately positioned and held still during the recording time. Once they have assumed the proper testing position, the video recording will begin and the DizzyDoctor application will start a verbal countdown until each recording session is complete.

 

The first recording is taken in the Dix-Hallpike right position. To assume this position, the patient must first turn their head 45 degrees to the right. They will then be instructed to lie back until their head is approximately 30 degrees hanging off the edge of table or bed but still also keeping their head approximately 45 degrees to the right. Once the DizzyDoctor App verifies the patient is in the correct position, the patient’s smart phone camera will begin to obtain a 10 second video eye recording. After the Dix-Hallpike right position testing is complete, the patient will be instructed to return to an upright seated position, with their head centered straight ahead, for another 10 second video eye recording. The DizzyDoctor App will then verbally instruct and guide the patient into the proper Dix-Hallpike left position. To assume this position, the patient will remain sitting and then first turn their head 45 degrees to the left. They will then be instructed to lie back until their head is 30 degrees off the edge of table or bed but still also keeping their head approximately 45 degrees to the left. Once the DizzyDoctor App verifies the patient is in the correct position, the patient’s smart phone camera will begin to obtain another 10 second video eye recording. After the Dix-Hallpike left position testing is complete, the patient will be instructed to return to an upright seated position, with their head centered straight ahead, for another 10 second video eye recording.

 

After all four testing positions have been completed, the recordings are then automatically stored onto the patient’s smart phone. The raw footage may then be reviewed on the patient’s phone. The eye recording session will automatically upload to the patient’s portal on the DizzyDoctor website when the iPhone has access to an internet connection. The recordings on the DizzyDoctor Website will be presented with eye tracking data as well as iPhone gyroscopic stability data during video playback. The patient may log on to view their data at any time or may give temporary access to their health care provider for viewing privilege. These recordings may later be viewed by the patient’s physician or other health care provider to aid in their diagnosis and treatment.
