    Area of Science:

    • Ophthalmology
    • Pediatric ophthalmology

    Background:

    • The Hirschberg test is a clinical method to assess eye alignment.
    • Accurate measurement is crucial for diagnosing strabismus in children.

    Purpose of the Study:

    • To determine the theoretical conversion factor for the Hirschberg test in children from birth to age 5.
    • To establish a reliable measurement standard for pediatric eye alignment.

    Main Methods:

    • Calculation of the theoretical conversion factor for the Hirschberg test.
    • Analysis of data from birth to 5 years of age.

    Main Results:

    • The theoretical conversion factor was calculated as 1 mm = 19.5 delta.
    • This conversion factor remained consistent across the observed age range (birth to 5 years).

    Conclusions:

    • The established conversion factor provides a stable and reliable method for Hirschberg testing in young children.
    • This finding supports consistent diagnostic criteria for strabismus in pediatric populations.
