An Overview of Preschool Vision Screening

Abstract

Although several vision screening techniques are available for infants, including Optokinetic Nystagmus, Preferential Looking and Visual Evoked Potential, none is routinely utilized. Visual deficits are often first detected through required preschool vision screenings. These screenings vary in their comprehensiveness and administration. No standardization for testing or administration exists. Referrals for further examination appear to be higher for those children receiving a thorough battery, suggesting that some of the testing procedures used have inappropriately high rates of false negatives.
