One hundred and sixty-five children from the school for the deaf were screened to find out the aetiology of deafness. The screening included routine ophthalmological examination. Aetiology was unknown in 33 children (20%). Prenatal infection was found to be the cause of deafness in 61 cases (36.96%). Rubella eye signs were found in 59 children (35.76%), whereas the history of rubella infection during the first trimester of pregnancy was found in only 33 of these cases (55.93%). Perinatal complications were seen in 20 children (12.12%). Twenty children (12.12%) had meningitis during their early childhood period. Routine ophthalmological examination helped us to pick up cases with rubella eye signs. Ophthalmological examination should be included as part of any study done to find out the cause of deafness.
