About 20 percent of children with sensorineural hearing loss also have eye disorders, a new study has found.
Sensorineural hearing loss, caused by damage to the inner ear or to the nerves that link the ear to the brain, affects up to three of every 1,000 children, according to background information in the study. Half of all cases in children are due to genetics, and one gene, GJB2, accounts for a large proportion of sensorineural hearing loss in whites.
