Video Head Impulse test (vHIT)

The Video Head Impulse test is done to determine the patient’s ability to clearly see objects while the head is moving, such as reading road signs while driving. This allows the audiologist to objectively assess the vestibulo-ocular reflex (VOR), which maintains steady vision during head movement by initiating a reflexive eye movement that is equal and opposite to that of the head movement. During the test, a gyrometer measures and matches the patient’s head and eye movements while the patient looks at a stationary target. It identifies abnormalities during fast head movements. The vHIT is very accurate and detect even the smallest abnormalities.
