Usher's syndrome is the most common condition that affects both hearing and vision. The major symptoms of Usher's syndrome are hearing loss and an eye disorder called retinitis pigmentosa, or RP. RP causes night-blindness and a loss of peripheral vision through the progressive degeneration of the retina. As RP progresses, the field of vision narrows—a condition known as ”tunnel vision” --until only central vision remains. Many people with Usher's syndrome also have severe balance problems.
