Diabetic Eye Screening


Diabetic Eye screening is an important phase in the treatment of patients with diabetes. People who have it are at risk of eye damage from diabetic retinopathy which can lead to sight loss if not treated.

Diabetic eye screening is an examination used to detect the condition early before it starts to affect your vision, usually diabetic retinopathy will not show any symptoms in its early stages however can be difficult to treat if symptoms start to show.

If detected early enough appropriate treatment can stop it from becoming worse. The test involves a consultant examining the back of the patients eye taking images of the retina.


When being tested the screening appointment will take around 60 minutes, the procedure will firstly be explained when you when you arrive and then you will proceed. The consultant will firstly test your vision and then by eye drops will be given to enlarge your pupils. This should take around 15 to 20 minutes which will then allow the photographs of your retina to be taken.

There is a flash of light when each photo is taken which shouldn’t be uncomfortable after 15 minutes your vision will become blurred and you may find it difficult to focus on objects that are close to you. Blurring can last between 2 to 6 hours (depending on the type of drops used). It is recommended to bring another person with you as you will not be able to drive home after.

Eye checks directly with a Consultant Ophthalmologist specialising in this condition are available privately at the Royal Free.
