Introduction: After an acute damage of the peripheral vestibular organ the vestibulo-ocular reflex usually recovers in the head impulse test. The present study was designed to quantify the dynamic changes of the vestibulo-ocular reflex during the head impulse test after acute peripheral vestibular damage. Furthermore vestibulo-ocular reflex changes during the head impulse test were compared to changes in the sensory organisation test (SOT) and in the dizziness handicap inventory (DHI).
Patients and methods: 5 patients were examined with the ICS Impulse (Otometrics), the SOT gemessen and the DHI. Examination dates were after day 1, month 1, month 3 and month 6.
Results: While a significant improvement in SOT and DHI was seen, covert and overt saccades still remained in the head impulse test. Slow recovery of the vestibulo-ocular reflex was seen. Late overt saccades declined after six months.
Discussion: Subjective complaints recover much quicker than the vestibulo-ocular reflex. Late overt saccades might be a parameter for central compensation.
