Diabetic retinopathy in the UK: screening, treatment and where stem cell research fits
Diabetic retinopathy often causes no symptoms until the damage is advanced, which is why screening matters so much. If you live with diabetes in the UK, this page explains what happens inside the eye, what the NHS does about it, and how experimental stem cell research relates to proven care.
Why diabetes harms the retina
Persistently high blood sugar weakens the tiny blood vessels that feed the retina. They may leak fluid, close off, or be replaced by fragile new vessels that bleed. The macula, which handles detailed central vision, is particularly vulnerable to swelling.
Stages of the condition
- Background retinopathySmall bleeds and leaks. Usually no symptoms and no treatment beyond tighter control.
- Pre-proliferative changesMore blocked vessels. Needs closer monitoring.
- Proliferative retinopathyNew fragile vessels grow and can bleed or pull on the retina. Needs prompt treatment.
- Diabetic maculopathySwelling at the centre of the retina that blurs reading and recognising faces.
NHS diabetic eye screening
In England, people with diabetes aged 12 and over are invited for digital retinal photography every year, and the other UK nations run similar programmes. Attending every appointment is one of the most effective things you can do for your sight. Tell your optometrist or GP promptly if your vision changes between screenings.
Treatments with genuine evidence
Blood sugar, pressure and cholesterol control
Steady control slows retinopathy more than any other measure and reduces the need for later treatment.
Laser treatment
Laser is used to treat abnormal vessels in proliferative disease and, in some cases, macular swelling.
Anti-VEGF injections
Injections into the eye reduce macular swelling and can stabilise or improve vision, and are usually repeated over time.
Vitrectomy surgery
When bleeding or scar tissue pulls on the retina, surgery can clear the eye and repair the damage.
How stem cell research relates to this
Researchers are studying whether cells can protect or repair retinal blood vessels. This is early-stage work, no approved stem cell therapy exists for diabetic retinopathy, and it must never replace screening, laser or injections. We consider it only as an investigational option after reviewing your reports.
Everyday steps that protect your eyes
Do not skip screening
A missed appointment can hide treatable disease.
Check your HbA1c trend
Falling levels are good for your eyes, but ask your team about how quickly to lower them.
Stop smoking
Smoking adds to the damage to small blood vessels.
Know the driving rules
Report relevant visual changes to the DVLA as required.
Planning from the UK
Upload your latest OCT, retinal photographs and injection history through our Upload Report page. We will review them and tell you honestly whether a further assessment is worthwhile, while your NHS retinal service continues your core care.

Get ConsultationFrequently asked questions
Can diabetic retinopathy be reversed?
Early changes may settle with better control, but established damage cannot be fully reversed. Treatment aims to protect the sight you have.
Will stem cell therapy replace laser or injections?
No. Those are proven treatments and should continue as advised by your retinal team.
How often do I need an eye check?
At least annually through screening, and sooner if you notice blurring, floaters or dark patches.
