    Pregnancy did not significantly alter key vision measurements like refractive error or corneal properties. Optometric examinations confirmed stable vision throughout gestation, benefiting pregnant individuals and eye care providers.

    Area of Science:

    • Ophthalmology and Optometry
    • Reproductive Health

    Background:

    • Pregnancy is associated with various physiological changes.
    • The impact of these changes on ocular parameters requires thorough investigation.

    Purpose of the Study:

    • To assess the longitudinal changes in key optometric parameters during pregnancy.
    • To determine if refractive error, corneal properties, or binocular vision measures are affected by gestation.

    Main Methods:

    • Two optometric examinations were performed on 93 pregnant subjects and 38 nonpregnant controls, spaced 3 months apart.
    • Subjects were grouped by trimester of pregnancy.
    • Statistical analyses included analyses of variance and t-tests to compare findings.

    Main Results:

    Related Experiment Videos

    • No significant changes were observed in refractive error during pregnancy.
    • Corneal curvature and thickness remained stable throughout gestation.
    • Accommodative amplitude, AC/A ratio, and fusion break ranges showed no significant alterations.

    Conclusions:

    • Pregnancy does not appear to induce significant changes in major optometric parameters.
    • These findings suggest ocular stability during gestation for refractive and binocular vision measures.
