Risk factors for failed vision screening
Reviewed by Fiona Rowe

Failure rates on vision screening tests were reported by age and racial / ethnic categories in a large sample of children with most aged 6-11 years. Many children resided in lower socioeconomic status areas. Data was taken from 9743 children. Nine hundred and fifty-one children with glasses were significantly more likely to be older and white. Groups did not differ significantly for estimated income. Of 4253 children, 598 failed one or more vision screening tests. Age was significantly associated with failed tests, as was African-American and Hispanic status. Approximately 14% of African-American and Hispanic children failed at least one test compared to 11% of white children. There was a significant difference in screening failure rates based on age and ethnicity depending on the different tests used: far vision test, plus lens test, random dot E test and near point acuity. The 9-11 year children had the highest rate of fails.
