    The Blind and Partially Sighted Registers in Melton Mowbray underestimate visual impairment prevalence. The partially sighted register is particularly inaccurate, missing half of eligible individuals.

    Area of Science:

    • Ophthalmology
    • Public Health
    • Gerontology

    Background:

    • Accurate registration of visual impairment is crucial for resource allocation and support services.
    • Previous studies suggest potential underestimation in existing registries for the elderly population.

    Purpose of the Study:

    • To assess the accuracy and completeness of the Blind and Partially Sighted Registers in Melton Mowbray.
    • To determine the prevalence of registrable visual impairment in the elderly population.

    Main Methods:

    • A cross-sectional prevalence survey was conducted in the population over 75 years old.
    • Data from the survey were compared against existing Blind and Partially Sighted Register data.

    Main Results:

    Related Experiment Videos

  • The Blind Register demonstrated high sensitivity and specificity but underestimated blindness prevalence by 1.1 times.
  • The Partially Sighted Register had high specificity but only 50% sensitivity, underestimating partial sight prevalence by 1.5 times.
  • Seven individuals (21% of the registrable visually impaired) were found to be eligible but unregistered.

    • Conclusions:

    • The current registration system for visual impairment in this elderly population is incomplete.
    • Improvements are needed, particularly for the Partially Sighted Register, to ensure accurate identification and support for visually impaired individuals.
