Retinitis Pigmentosa Treatment in London
The UK's leading centre of excellence for Retinitis Pigmentosa Treatments
What Is Transcorneal Electrical Stimulation (TES)?
TES is a non-invasive therapy that uses gentle electrical currents to stimulate retinal activity and slow the progression of Retinitis Pigmentosa. The treatment involves a wearable device designed for home use, featuring two electrodes—one placed on the eye and one on the forehead—delivering low-voltage pulses (under 1000mV) to support retinal function.
First Eligibility Session
Consultant review, imaging, and initial TES delivery
Second Eligibility Session
Repeated one week later to confirm response
Ongoing Therapy (if eligible)Procedure
Weekly sessions delivered in-clinic or with a home-use device
Does This Sound Like You?
TES may be right for you if you:
- Have a confirmed diagnosis of Retinitis Pigmentosa
- Experience tunnel vision or night blindness
- Were told by your NHS specialist that nothing more can be done
- Want to explore advanced options not widely available
- Are seeking a therapy designed for home use

Eligibility Assessment for TES Therapy
Because RP results from over 40 different gene mutations, not all patients respond equally to TES. Our eligibility assessment ensures that only those with a measurable benefit proceed to long-term treatment.
Assessment Format:
- Two clinic visits, spaced one week apart
- Each visit includes consultant review, imaging, and a TES treatment
- Immediate post-treatment feedback to determine benefit
What We Measure:
- Night vision
- Contrast sensitivity
- Brightness and colour perception
- Visual acuity
- Peripheral awareness
Most candidates experience improvement in at least 3 out of 5 areas, with temporary gains lasting 2–3 days.
Fee: £600 (includes both sessions)
If consistent improvement is observed across both visits, we will guide you into ongoing care options.
Home Use Device
- Year 1 Package – Device, 12-month electrode supply, training, annual review, and direct support
- Year 2+ Package – Electrode supply, reviews, ongoing support
- Payment plans available
International Patients
We welcome international patients seeking evaluation and treatment for RP. Our clinic offers coordinated eligibility assessments and training for long-term home use, with virtual follow-ups available.
How Much Does Treatment Cost?
Our pricing is clear and all-inclusive—covering consultation, surgery, and aftercare. You’ll receive a personalised quote based on your needs after your initial assessment.

Retinitis Pigmentosa (RP): FAQ — Treatments & What to Expect
Understanding RP & What It Means
What is Retinitis Pigmentosa (RP)?
RP is a group of inherited retinal disorders in which the light-sensing photoreceptor cells in the retina gradually deteriorate. Over time this leads to progressive vision loss — typically beginning with night blindness, loss of peripheral (side) vision, and eventually narrowing of the visual field (often referred to as “tunnel vision”).
How is RP diagnosed at a specialist clinic?
Diagnosis typically involves a combination of tests: dilated retinal exam, imaging of the retina (e.g. OCT, fundus autofluorescence), visual field testing to assess peripheral vision loss, and possibly electro-diagnostic tests (electroretinography, ERG) to measure retinal function. Genetic testing can also help identify the gene mutation causing RP — useful both for prognosis and eligibility for future therapies.
Treatments & Management Options at The Harley Street Eye Centre and Beyond
Is there a cure for RP?
At present, there is no universal cure for RP. Because RP is caused by many different gene mutations, a single approach does not suit everyone. However — thanks to ongoing research — several therapies and supportive treatments are available to help slow progression, preserve vision, or manage symptoms.
What treatment does The Harley Street Eye Centre offer for RP?
The centre offers a therapy known as Transcorneal Electrical Stimulation (TES), which uses gentle electrical currents to stimulate the retina and support retinal function. This non-invasive therapy may help slow progression of RP.
How does TES work and what does it involve?
TES involves placing a small electrode on the eye and another on the forehead, delivering low-voltage pulses (under 1000 mV) designed to stimulate retinal cells. Initial eligibility requires a consultant review, retinal imaging, and two trial sessions one week apart to assess response. If a measurable benefit is seen (in night vision, contrast, peripheral awareness, etc.), ongoing treatment — potentially at home — may be offered.
Other Treatment & Research Options (Global / Experimental)
Are there other therapies under development for RP?
Yes — global research is very active. Approaches under investigation include:
- Gene therapy (for certain genetic variants) that aims to deliver correct gene copies to retinal cells.
- Stem-cell / cell-replacement therapy, aiming to regenerate lost photoreceptors. Early-phase trials have been performed.
Optogenetics or “artificial vision” systems (e.g. retinal prostheses) that attempt to bypass damaged photoreceptors by stimulating surviving retinal or optic-nerve cells electrically or chemically.
Could I be eligible for gene therapy or clinical trials?
Does that mean early diagnosis matters even more?
Managing Vision Loss & Quality of Life
If treatment isn’t available, how can I manage RP in day-to-day life?
Many people with RP use low-vision aids and adaptive strategies: magnifiers, strong-contrast lighting, electronic devices, mobility aids, consistent positioning of belongings, and orientation training. Rehabilitation and support help maintain independence and reduce risk of accidents.
Can associated eye conditions be treated in RP patients?
Yes. Some people with RP develop other treatable eye problems — for example cataracts, macular oedema, or other retinal complications. Treating these can improve clarity and comfort even if RP itself remains.
Suitability & Expectations at The Harley Street Eye Centre
What happens during the initial RP consultation at the Centre?
Your visit would involve detailed retinal imaging, functional testing (visual field, contrast, night vision), possibly genetic testing if needed or recommended, and a discussion of all suitable treatment or management options — including TES and supportive vision aids.
What can TES realistically achieve?
TES is not a cure; it aims to support retinal cell function and potentially slow further deterioration — helping preserve remaining vision for longer. Results vary between individuals; some may notice modest improvements in night vision or contrast, while others may experience mainly stabilisation.
Why choose The Harley Street Eye Centre for RP care?
Because the Centre offers access to TES therapy (rare in the UK), consultant-led retinal care, personalised evaluation, and possibility of long-term support including monitoring. For patients seeking options beyond standard “wait and see,” the Centre provides a thoughtful, measured, and up-to-date approach.
