The inner ear, or vestibular system, controls balance and tells your body where you are in space. Both inner ears are connected to the brain and the eyes.
Bilateral Vestibular Loss (BVL) is a complete loss of vestibular function in both inner ears. Partial damage to both inner ears is called Bilateral Vestibular Hypofunction (BVH).
People with BVL or BVH have difficulty maintaining balance, especially when walking in the dark or on uneven surfaces. This can lead to an increased risk of falling, visual blurring, dizziness, imbalance, and a degradation in overall physical condition.
