Among 145 children with severe hearing loss 35 had a characteristic retinopathy. Only few of these had additional malformations. Most of these children (28) were born during the months September through February. Rubella antibodies were present more frequently than in matched controls. No such difference was found for cytomegalovirus and herpesvirus hominis.
