Summary
Many Danish patients with diabetes lack access to systematic diabetic retinopathy screening. Implementing planned screening programs could significantly improve coverage across all Danish counties.
Area of Science:
- Ophthalmology
- Public Health
- Diabetology
Background:
- Diabetic retinopathy is a leading cause of preventable blindness.
- Systematic screening programs are crucial for early detection and intervention.
- The current status of diabetic retinopathy screening in Denmark was previously unevaluated.
Purpose of the Study:
- To assess the current organization and methods of diabetic retinopathy screening in Denmark.
- To identify regional variations in screening practices across Danish counties.
- To determine the proportion of diabetic patients lacking access to systematic screening.
Main Methods:
- A nationwide questionnaire survey was conducted in 2002.
- The survey targeted all 15 county ophthalmology departments and one ophthalmology practice.
- Data on screening organization, methods, and future plans were collected.
Main Results:
- Only six out of 15 counties had systematic diabetic retinopathy screening programs in place.
- Three counties reported plans for systematic screening, while four had no such plans.
- Significant variation existed in the organization and methods of screening where implemented.
Conclusions:
- Approximately 43% of Danish patients with diabetes resided in counties without systematic screening.
- If all counties implement planned screening, coverage could increase, reducing the unprotected population to 17%.
- There is a clear need to expand and standardize diabetic retinopathy screening services in Denmark.
