    Summary
    This summary is machine-generated.

    Infants have significantly higher rates and amounts of astigmatism than school-aged children. Astigmatism decreases in infants during their first year and declines further by age three.

    Area of Science:

    • Ophthalmology
    • Developmental Biology
    • Pediatric Optometry

    Background:

    • Astigmatism is a common refractive error affecting vision.
    • Understanding astigmatism development in early life is crucial for timely intervention.
    • Prevalence and severity in infants compared to older children are not well-established.

    Purpose of the Study:

    • To quantify and compare the incidence and amount of clinically significant astigmatism in infants versus school-aged children.
    • To investigate the developmental trajectory of astigmatism during the first three years of life.

    Main Methods:

    • Comparative analysis of astigmatism data between infant and school-aged cohorts.
    • Longitudinal observation of astigmatism changes within the infant group over time.

    Main Results:

    • Infants exhibit a tenfold higher incidence of clinically significant astigmatism compared to school-aged children.
    • The amount of astigmatism is considerably greater in infants.
    • Astigmatism begins to decrease in the second half of the first year of life and its incidence declines during the third year.

    Conclusions:

    • Infantile astigmatism is significantly more prevalent and severe than previously recognized.
    • The findings suggest a distinct developmental pattern of astigmatism in early life.
    • These results have implications for understanding the causes and neurological effects of astigmatism.
