Bilateral vestibulopathy is defined as a dysfunction of both vestibular labyrinths or vestibular nerves simultaneously. It is mainly manifested by stance and gait instability, typically worse in the dark or on uneven surfaces, and blurring of vision when moving. Patients do not have difficulties under static conditions. A clinically essential examination is the head impulse test. Quantification of bilateral impairment of vestibular function using calorization, sinusoidal stimulation, or video Head Impulse testing is required to confirm the diagnosis. The most common causes include the use of vestibulotoxic drugs, bilateral Menière's disease, post-meningoencephalitis, or autoimmune disease. However, the etiology of bilateral vestibulopathy remains idiopathic in a large proportion of patients.
