Diabetic retinal screening (diabetic eye screening) is a test used to detect diabetic retinopathy, an eye condition caused by diabetes that can damage the retina and lead to sight loss if not identified and treated early.
Who should attend?
- In England, people with Type 1 or Type 2 diabetes aged 12 years and over are invited for screening
- Most people are invited every 1–2 years, depending on previous screening results.
What happens at the appointment?
The examination usually takes around 30 minutes and includes:
- A vision check.
- Eye drops to dilate (widen) the pupils.
- Digital photographs of the back of the eyes (retina).
Important advice for patients
- The dilating eye drops can cause blurred vision for several hours.
- Patients should not drive after the appointment and should arrange alternative transport home.
Why is it important?
Diabetic retinopathy often has no symptoms in its early stages. Screening can detect changes before vision is affected, allowing treatment to prevent or reduce sight loss.
