Study Notes

vHIT Set-Up

Connect goggles to the computer before launching OTOsuiteV.
Enter patient data: Last Name, First Name, Gender, Birthdate, and save.
Confirm recording status; restart the program if necessary.
Replace foam cushion weekly or when stained; clean glasses with a microfiber cloth.
Position the patient 3 feet from the wall with adequate light.
Ensure goggles fit snugly; position the strap behind the ears, keeping hair tucked away. Center the dot on the wall at eye level.

Running vHIT

Select "Collect" in the Workflow Panel; direct patient to look straight ahead.
Center the green box on the pupil; adjust settings to ensure the pupil appears white.
Address eyelash interference by either physically opening the eye wider or using an eyelash curler.
On centering the head and ROI, proceed to the calibration tab.
Activate the red laser and instruct the patient to align it with the wall dot without moving their head.
Click "Run" to calibrate; ensure horizontal alignment of laser dots.
Conduct a head check: gently move the patient's head left and right for 10 seconds.
Provide test instructions, emphasizing head stability and minimizing blinking.
Initiate head movement rapidly to elicit a high-pitched acceptance sound for successful tests; aim for 20 accepted tests per direction.
Transition to the LARP test, aligning the patient’s head and centering the pupil.
Maintain head position at a 45-degree angle and configure eye settings as necessary.
Grip the patient's head securely, moving it quickly as needed to complete LA and RP testing; target 20 accepted tests in both directions.

Troubleshooting Tips

Analyze rejection reasons: check movement speed, head stability, and whether the goggle strap was touched.
Monitor pupil display cleanliness and adjust eyelid positioning if necessary.
Instruct the patient on proper eye-opening techniques during head movements.

Finishing the Test

Remove goggles and store them appropriately; the test saves automatically.
Access the patient’s vHIT profile, select "Report," and save to the Norcal Brain Center drive using the format: “First name Last name VHIT Test date.”
Upload the report to the patient's Jane system and delete from the drive afterward.

vHIT Set-Up

Connect goggles to the computer prior to launching the OTOsuiteV program.
Create a new patient entry by inputting Last Name, First Name, Gender, and Birthdate, then save the profile.
Confirm the goggles are recording; if not, restart the program.
Replace foam cushion weekly or if visibly dirty to maintain hygiene.
Clean goggles using a microfiber cloth to ensure clear visibility.
Position the patient approximately 3 feet from the wall, ensuring the lamp is turned on and fully illuminated.
Secure goggles on the patient's head, tucking hair behind ears, and adjust for proper centering and eye level alignment with the wall dot.

Running vHIT

Begin data collection by selecting “Collect” in the Workflow Panel.
Ensure the patient is looking straight ahead, centering the tracking box over the pupil as necessary.
The pupil's color should appear white; adjust with plus or minus signs if needed.
Address issues with eyelash obstruction by widening the right eye or using an eyelash curler.
Ensure head is centered and the region of interest (ROI) is aligned with the pupil before moving to calibration.
Activate the red laser for calibration, instructing the patient to align it with the wall dot while keeping their head straight.
Conduct head checks by moving the patient's head left and right for 10 seconds after calibration.
Provide clear instructions to the patient to minimize blinking and communicate needs during the test.
Execute quick head movements (~10 degrees) to complete the tests, striving for 20 accepted head moves in both left and right directions.
Transition to LARP by aligning the laser with the wall dot prior to beginning further assessments.
Position the patient's head at a 45-degree angle to the right for continued testing.

Troubleshooting Tips

Assess testing rejects by reviewing technique, speed of movement, head stability, and whether the goggle strap is being touched.
Ensure the patient’s pupil display is clean and adjust as needed if issues arise during head movements.
Instruct patients to keep their eyes open throughout to avoid closing during head turns.

Finishing the Test

Once testing concludes, remove goggles and place them on the designated holder; data saves automatically.
Access the patient’s vHIT profile, select “Report” to save the testing report in a specific format (First Name Last Name vHIT Test Date) to the Norcal Brain Center drive.
Upload the report to the patient's Jane account, and remember to delete it from the drive post-upload.
