Visual impairment in Danish children 1985.

T Rosenberg

    Acta Ophthalmologica
    |February 1, 1987
    PubMed
    Summary

    The incidence of notification for childhood visual impairment varied significantly by birth year, highlighting the impact of congenital and neonatal conditions. Further research into specific causes is crucial for effective prevention strategies.

    Area of Science:

    • Ophthalmology
    • Pediatrics
    • Epidemiology

    Background:

    • Childhood visual impairment presents a significant public health concern.
    • Understanding the epidemiology of visual impairment is essential for developing targeted interventions.
    • The Danish National Register for Visually Impaired Children serves as a key data source.

    Purpose of the Study:

    • To analyze the incidence and etiological factors of visual impairment in children.
    • To investigate the anatomical location and associated handicaps related to visual impairment.
    • To evaluate the utility of an epidemiological method for planning prevention strategies.

    Main Methods:

    • Cross-tabulation of ophthalmological diagnoses with demographic and etiological data.
    • Calculation of 'incidence of notification' (IN) per birth year group.
    • Analysis of the relationship between etiology and additional handicaps.

    Main Results:

    • The incidence of notification varied widely, with higher rates in more recent birth year groups, emphasizing congenital and neonatal factors.
    • Approximately 90% of blinding causes involved the posterior segment, optic pathways, or brain.
    • 38% of cases lacked a specific identifiable etiology, and 48% had central nervous system involvement.

    Conclusions:

    • The presented epidemiological method is valuable for planning preventive strategies for childhood visual impairment.
    • Future efforts should focus on increasing diagnostic specificity and identifying specific etiologies.
    • Targeted interventions are needed, particularly for congenital and neonatal visual impairments.
