    Area of Science:

    • Ophthalmology
    • Developmental Pediatrics
    • Public Health

    Background:

    • Preschool vision screening often involves compromises in testing methods, impacting accuracy and efficiency.
    • Traditional screening methods may lead to high rates of untestable results due to the challenges of testing young children.
    • Existing methods may require additional resources like personnel or extensive child training.

    Purpose of the Study:

    • To describe a developmental approach to preschool vision screening.
    • To evaluate the effectiveness and efficiency of this developmental screening method.
    • To compare the proposed method with existing screening tests.

    Main Methods:

    • A developmental vision screening test was employed, adapting acuity testing materials to individual child capabilities assessed beforehand.

  • The method's untestability rate was compared to the Society for Prevention of Blindness test.
  • Acuity data from the developmental test, the Society for Prevention of Blindness test, and a pediatric ophthalmologist's screening were compared.

    • Main Results:

    • The developmental approach yielded approximately half the number of untestable results compared to the Society for Prevention of Blindness test.
    • Acuity data from the developmental test and the Society for Prevention of Blindness test showed strong agreement.
    • Both screening tests demonstrated good agreement with a pediatric ophthalmologist's screening results.
    • Behavioral ratings during the developmental screening accurately predicted diagnostic cognitive test results.

    Conclusions:

    • The developmental vision screening test is a cost-effective method for preschool vision screening due to its low untestability rate and valid acuity data.
    • This approach minimizes common compromises in preschool vision screening, such as increased cost or reduced precision.
    • The test's ability to predict cognitive outcomes enhances its value for comprehensive preschool screening.
