Diabetes screening identifies changes in blood sugar control and early complications before symptoms develop. Early detection allows timely treatment to reduce the risk of serious problems, including sight loss.
Eye Health Impact
High blood sugar can damage the small blood vessels in the retina, leading to diabetic retinopathy and macular oedema. These changes may progress silently until vision is threatened.
- Regular retinal screening photographs or scans look for early signs of damage
- Prompt laser, injection, or systemic treatment can prevent or limit sight loss
- Good control of blood sugar, blood pressure, and cholesterol reduces risk
- Screening does not replace routine eye examinations for other conditions
Broader Health Reasons
Screening for diabetes and its complications also protects the heart, kidneys, and nerves. Participation in national or local programmes is therefore strongly recommended.
- People at higher risk, such as those with a family history or obesity, benefit from regular checks
- Inform your eye care provider if you have diabetes or abnormal results
- Attendance at annual retinal screening is vital even if vision seems normal
- Results help your healthcare team adjust treatment to protect long-term health
