The screening test usually takes around 30 minutes.
At your appointment, screening staff will:
- Explain the screening process and record your details and level of sight
- Administer eye drops to make your pupils larger, so the retina can be seen more clearly
- Take digital photographs of your retina (the light-sensitive layer of tissue at the back of the inner eye that acts rather like a film in a camera)
Please note that the photograph is painless and the camera does not come into contact with the eye. However, the eye drops may cause some stinging for a few seconds and blurred vision for between two to six hours after the test
