Stem cell therapy for retinitis pigmentosa in the UK: a clear-eyed guide
A retinitis pigmentosa (RP) diagnosis usually arrives in a short clinic appointment, and the questions come afterwards. This page is written for people in the UK who want to understand the condition properly, know what the NHS offers, and see where stem cell therapy honestly stands before deciding anything.
What RP is
RP is one of the most common inherited causes of sight loss. Different genes can trigger it, but the effect is similar: the retina’s rod cells fade first, then the cones. Many people describe the early years as trouble with dusk and dimly lit pubs or cinemas, followed by a slowly closing field of view.
Early signs worth reporting to your optometrist or GP
- Poor night visionNeeding far longer than friends to see after the lights go down.
- Knocking into thingsMissing furniture, kerbs or people on one side.
- Glare problemsBright sun or headlights feel painful and slow to recover from.
- Relatives with sight lossParticularly when onset was in youth or middle age.
How diagnosis usually runs in the UK
Your optometrist or GP refers you to a hospital eye service, and complex cases go on to an inherited retinal disease clinic. There you can expect retinal imaging, visual field tests and, at specialist centres, an electroretinogram. Genetic testing is offered through the NHS genomic medicine service for many patients, and a clear gene result can open doors to clinical trials.
Treatments with genuine evidence
Only a few options have proper evidence behind them for RP.
Gene therapy for RPE65
Voretigene neparvovec has been recommended by NICE for eligible patients with confirmed biallelic RPE65 disease. It applies to a very small group and only after genetic confirmation.
Cataract surgery
Lens clouding appears earlier in RP. Surgery can restore brightness and contrast even when the retina remains affected.
Treating macular swelling
Fluid in the central retina can sometimes be eased with drops or tablets, helping reading vision.
Clinical trials
Several gene and cell studies are running in specialist centres. Your NHS consultant is the best person to tell you which ones you may qualify for.
Where stem cell therapy fits
Stem cell therapy for RP is investigational. The aim is to support surviving photoreceptors and the supportive retinal layers, not to rebuild the retina. It is not an approved treatment, outcomes vary, and it sits outside the NHS pathway, so your NHS team will not fund or provide it. We assess your reports first and tell you plainly if the approach is unlikely to help.
Practical support in the UK
Certificate of Vision Impairment
Your consultant can issue a CVI, which allows registration as sight impaired and opens access to support.
Charities
Retina UK and RNIB offer advice, peer groups and helplines.
Driving
Visual field loss can affect your licence, so check current DVLA rules and tell them when required.
Work support
Access to Work can fund equipment and adjustments in employment.
Planning from the UK
Send recent scans, field tests and any genetic report through our Upload Report page. Ask your hospital for copies of your notes, check that your travel insurance covers treatment abroad, and keep your NHS follow-up going alongside anything we advise.

Get ConsultationFrequently asked questions
Will the NHS treat me if I have stem cell therapy abroad?
You remain entitled to NHS care for complications and monitoring, but the NHS does not provide or fund the stem cell treatment itself.
Is a gene result essential?
It is useful for trials and family planning. We can still review your other reports if you do not have one.
Can stem cell therapy stop RP?
There is no evidence that it can stop RP. It is experimental and any benefit is uncertain.
