Question

In head impulse test, the following finding is seen in right vestibular neuritis:

• A. On rotating head to right, left saccade
• B. On rotating head to left, right saccade
• C. On rotating head toward right, right saccade
• D. On rotating to the left, left saccade

Hint:

In vestibular neuritis, a head impulse test will show compensatory saccades in the opposite direction of the impaired side.

Answer 1

The Correct Option is A

The head impulse test is commonly used to evaluate the function of the vestibular system, particularly in diagnosing vestibular neuritis. When a patient has right vestibular neuritis, the vestibular system on the right side is impaired. During a head impulse test, you move the patient's head rapidly to one side and observe the eyes.

For right vestibular neuritis, the following occurs:

• On rotating the head to the right: The right vestibular system fails to detect the motion due to the impairment. This results in a left compensatory saccade being seen as the eyes overshoot due to diminished vestibular input from the right side.

Hence, the correct finding in right vestibular neuritis is: On rotating head to right, left saccade.
