Children's Eye Screening South Australia (CESSA): diagnostic performance of a vision screening programme for 7-9-year-olds.

Seventeen percent of a school-based sample of South Australian children aged 7-9 years were identified as having vision disorders, such as refractive errors and amblyopia risk factors, effectively detected using a combination of vision measurement and photorefraction.

These findings support improved vision surveillance in children in South Australia, which could include an instrument-based vision screening programme with appropriate thresholds.
