Diabetic eye screening cost
Free for every UK resident with diabetes, delivered annually by the NHS Diabetic Eye Screening Programme. Separate from the standard sight test, dedicated to looking for diabetic retinopathy through retinal photography. Eligibility starts at age 12; invitations are automatic once registered.
What the DESP programme does
The NHS Diabetic Eye Screening Programme delivers annual retinal photography for everyone with diabetes aged 12 and over. The purpose is to detect diabetic retinopathy (damage to the small blood vessels of the retina caused by raised blood sugar) before it causes irreversible sight loss. Early detection allows referral to ophthalmology for treatment that can preserve vision.
DESP is a dedicated public health screening programme, not a routine eye test. It is delivered through regional NHS screening providers rather than high street optometry in most of England. The screening uses standardised digital retinal cameras, two photos per eye, graded by trained NHS staff against national quality standards. The grading system is the same across the country: no retinopathy (R0), background retinopathy (R1), pre-proliferative (R2), proliferative (R3), plus maculopathy assessment (M0 or M1) and ungradable images.
Annual screening from age 12 reflects the cumulative risk of retinopathy with diabetes duration. Almost every person with Type 1 diabetes will develop some retinopathy within 20 years of diagnosis; the figure is lower but still substantial for Type 2. Early detection through annual photography catches sight-threatening disease before symptoms appear, allowing laser or intravitreal injection treatment that has been shown in randomised trials to reduce permanent sight loss.

What happens at a DESP appointment
Check in
Confirm name, date of birth, and diabetes diagnosis with the screener.
Pre-screening questions
How long since you have eaten, any allergies to eye drops, any current eye problems or symptoms.
Dilating drops
Tropicamide drops are put into both eyes. Stinging for a few seconds, then 20 minutes to wait for the pupils to dilate.
Retinal photography
Chin on the camera support, look at the target light. Two photographs per eye. Each photo takes around 5 seconds; the whole imaging session is around 5 minutes.
Aftercare advice
Vision will be blurry for 4 to 6 hours and you will be sensitive to bright light. Do not drive. Bring sunglasses if it is sunny outside.
Results by post
Photos sent to a grading centre. Results arrive within 6 weeks, with a copy to your GP. Most people get an all-clear and a 12-month return invitation.
US equivalent: Medicare-covered diabetic eye exam
The US does not have a single equivalent to the NHS DESP national programme. Medicare Part B covers an annual diabetic eye exam for beneficiaries with diabetes, performed by an ophthalmologist or optometrist. Coverage applies after the Part B deductible with 20% coinsurance unless covered by a Medigap policy. Most private US insurance plans similarly cover annual diabetic eye exams as a preventive service.
The American Diabetes Association recommends a comprehensive dilated eye exam at diagnosis for Type 2, within 5 years of diagnosis for Type 1, and at least every 1 to 2 years after. See the US eye test cost page for billing details.
Common questions
How much does diabetic eye screening cost?
Free for everyone with diabetes in the UK, delivered by the NHS Diabetic Eye Screening Programme (DESP) in England and equivalent programmes in Scotland, Wales, and Northern Ireland. Eligibility starts at age 12. There is no charge, no co-pay, no cost beyond your time at the appointment.
Is diabetic eye screening the same as a standard eye test?
No. DESP is a dedicated annual retinal photography screening service looking specifically for diabetic retinopathy. A standard NHS sight test at a high street optician is a full eye examination covering visual acuity, refraction, eye pressure, and broader eye health. People with diabetes should have both: DESP annually by invitation, plus an annual NHS-funded sight test (diabetes triggers annual rather than two-yearly funding).
How do I get invited to diabetic eye screening?
Automatically, once you are registered as having diabetes on your GP record. The first invitation arrives within around 12 weeks of diagnosis for adults, and from age 12 for children with diabetes. The invitation letter tells you the date, time, and location. Annual invitations continue thereafter.
What happens at a diabetic eye screening appointment?
Drops are put into both eyes to dilate the pupils (takes around 20 minutes to work). A digital retinal camera then takes two photographs of each eye through the dilated pupil. The whole appointment takes around 30 minutes including dilation time. You cannot drive home because the drops blur your vision for several hours; arrange transport.
When do I get the results?
By post within around six weeks. The photographs are read by trained graders, not at the appointment. Three possible outcomes: no retinopathy (return for screening in 12 months), background retinopathy (return in 12 months, optometrist informed), or referable retinopathy (referred to hospital eye service for assessment within six weeks).
Can I have diabetic eye screening at a high street optician?
Not as part of the NHS DESP itself in most regions. DESP is delivered by regional NHS centres, hospital clinics, mobile units, or specific community optometry sites that hold a DESP contract. A few regions do contract high street opticians for DESP delivery; most do not. You attend the location given in the invitation letter, separate from your routine optometrist appointments.
