Blind and partially sighted registration rates in Avon remained stable, except for a significant reduction in cataract cases. Diabetic registrations held steady, while age-related macular degeneration increased, indicating evolving trends in vision impairment.

Area of Science:

  • Ophthalmology
  • Public Health
  • Epidemiology

Background:

  • Understanding trends in blindness and partial sight is crucial for public health planning.
  • Previous national data from Sorsby over 20 years ago provides a baseline for comparison.
  • The study examines recent registration data to identify changes in causes of vision impairment.

Purpose of the Study:

  • To analyze blind and partially sighted registration forms in Avon over a two-year period.
  • To compare current registration rates with historical national data.
  • To identify trends in the causes of blindness and partial sight.

Main Methods:

  • Analysis of all blind and partially sighted registration forms from Avon.
  • Comparison of Avon's data with national figures from Sorsby's study.

  • Examination of changes in registration rates per 100,000 population for specific conditions.

    • Main Results:

    • Overall blind registration rates per 100,000 population showed no marked change compared to historical data.
    • A significant reduction in registrations attributed to cataract was observed.
    • Diabetic registrations remained stable, and an increase in registrations for age-related macular degeneration was noted.

    Conclusions:

    • Cataract is no longer a leading cause of registered blindness in the studied population.
    • Stable diabetic registrations may be encouraging given population growth.
    • Age-related macular degeneration is an increasing cause of vision impairment requiring attention.
