[Hearing disorders associated with vision disorders in children].

Hearing and eye-sight are very important for the development in children. Early diagnosis of disorders of these organs is therefore essential to ensure the development of affected children from early age, or to provide a correction (hearing aid, glasses) or to enlist these children in special schools. The authors found that in schools for children with impaired eye-sight and schools for children with impaired hearing there were 6.7% children with impairment of both sense organs. The most frequent cause of disorders of both sense organs was intrauterine damage (45.7%), in 25.7% of the investigated children the cause was unknown, in 20% it was genetically conditioned and in 8.6% the cause was postnatal. Therefore when a disorder of one sense organ is revealed, it is necessary to examine on a preventive basis also the other sense organ.
