    Summary
    This summary is machine-generated.

    New CT scan technology allows precise measurement of ocular dimensions and volume. Ocular volume changes with age and sex, with rapid growth in infancy and a decline after age 30.

    Area of Science:

    • Ophthalmology
    • Radiology
    • Biometry

    Background:

    • Computed Tomography (CT) scans have advanced oculometric research.
    • Accurate measurement of ocular dimensions is crucial for understanding ocular volume.
    • Ocular volume's relationship with age and sex requires further investigation.

    Purpose of the Study:

    • To estimate ocular volume using CT scans.
    • To analyze the relationship between ocular volume, age, and sex.
    • To establish normative data for ocular dimensions.

    Main Methods:

    • Utilized 100 CT orbit scans of presumed normal eyes.
    • Measured ocular dimensions to estimate ocular volume.
    • Analyzed data based on age and sex.

    Main Results:

    • Presented mean values and normal variations of ocular volumes across different ages and sexes.
    • Observed rapid eyeball growth in the first 24 months of life.
    • Noted peak ocular volume between 18-30 years, followed by a reduction.

    Conclusions:

    • Ocular volume exhibits distinct patterns of change throughout the lifespan.
    • Findings provide a reference for identifying ocular abnormalities like microphthalmia and macrophthalmia.
    • CT-based oculometry offers valuable insights into normal and abnormal eye development.
