The concept of chronic vestibular insufficiency (CVI) is usually based on bilateral (or, less frequently, unilateral) dysfunction of peripheral vestibular structures. The most relevant associated complaints are unsteadiness of gait, oscillopsia (i.e. apparent motion of the visual scene) with head movements, and impaired spatial orientation. Amongst the 50% of CVI patients that receive a specific diagnosis, previous treatment with vestibulotoxic antibiotics (such as gentamicin), bilateral Menière’s disease (MD) and meningoencephalitis are the top three disorders identified. Treatment strategies for CVI focus on optimizing the other sensory systems involved in balance and spatial orientation, whereas therapy for the underlying cause brings about a significant improvement only in a minority of cases.
