About diabetic eye screening services

Diabetic eye screening is carried out in north central London by the North Central London Diabetic Eye Screening Programme (NCL-DESP).

NCL-DESP is provided by North Middlesex University Hospital NHS Trust which conducts screening across five London boroughs: Barnet, Camden, Enfield, Haringey and Islington.

Eye screening is a key part of your diabetes care, and if you are diabetic, you should make sure you have a specialist diabetic eye screening test every year. This is because your eyes are at risk of damage from diabetic retinopathy, a condition that can lead to sight loss if it's not treated. Screening is a way of detecting the condition early before you notice any changes to your vision.

How does diabetic eye screening help? 

If diabetic retinopathy is detected early enough, treatment can stop it getting worse. Otherwise, by the time symptoms become noticeable, it can be harder to treat and your sight could be damaged.

Diabetic retinopathy occurs when diabetes affects small blood vessels, damaging the part of the eye called the retina. When the blood vessels in the central area of the retina (the macula) are affected, it is known as diabetic maculopathy.
