Refractive error in a Puerto Rican rural population.

    Journal of the American Optometric Association
    |November 1, 1990
    PubMed
    Summary

    This study investigated refractive error distribution in migrant workers and families in Puerto Rico. Myopia was most common in young adults, while hyperopia increased with age, with hyperopic astigmatism prevalent overall.

    Area of Science:

    • Ophthalmology
    • Public Health
    • Epidemiology

    Background:

    • Refractive errors are a significant global health concern.
    • Understanding refractive error distribution is crucial for targeted eye care interventions.
    • Migrant populations may face unique health challenges, including ocular conditions.

    Purpose of the Study:

    • To determine the prevalence and distribution of refractive errors.
    • To analyze age-specific patterns of myopia and hyperopia.
    • To assess the occurrence of astigmatism in a migrant worker community.

    Main Methods:

    • Screening of 1,109 individuals aged 5-81 years using a modified clinical technique.
    • Data collection on refractive error types: myopia, hyperopia, astigmatism, anisometropia, and emmetropia.
    • Age-stratified analysis of refractive error prevalence.

    Main Results:

    • 10.2% myopia, 17.7% hyperopia found in the study population.
    • Myopia peaked in the 11-20 and 21-30 year age groups.
    • Hyperopia prevalence increased from age 31-70, with hyperopic astigmatism being more common than myopic astigmatism.

    Conclusions:

    • Refractive error patterns vary significantly with age in this migrant population.
    • Targeted eye health programs are needed, considering age-specific refractive error prevalence.
    • The findings highlight the importance of vision screening in migrant communities.
