Vision screening of children: a review of methods and personnel involved within the UK.

The validity of vision screening of children for amblyopia, squint and significant degrees of ametropia is reviewed. The suitability of the tests used in screening, the age at which they are applied and the personnel involved is assessed. Some suggestions for improvement are made with particular reference to the optometrist's role, especially in view of the proposed child health surveillance scheme to be undertaken by selected general medical practitioners.
