Evaluation of vision screening in five- to eight-year-old children living in Region Västra Götaland, Sweden - a prospective multicentre study.

Our results showed that a vision screening referral cut-off limit of VA <0.65 would leave undetected refractive errors. Residual amblyopia was uncommon. Accurate referral criteria, retesting and training of those performing the screening as well as re-evaluation of the screening programme are all important.
