Visual screening of pre-school children.

Abstract

In an attempt to reduce the incidence of persistent amblyopia and related disorders, routine screening of the visual function of pre-school children has been introduced in Ayrshire, the tests being carried out by orthoptists. A pilot study confirmed the feasibility of the screening. Under the definitive scheme, whose first three months' results are presented, the children are examined as near as possible to their homes and the average attendance rate has been 86%. Thirty-seven of 442 children were referred to an ophthalmic clinic with suspected abnormalities (only one of which was not confirmed) that had not been picked up by the GP or welfare clinic. It is concluded that visual screening of pre-school children is administratively feasible and welcomed by parents, and that it can detect abnormalities missed by traditional procedures-which according to these results may be more than half of the total.
