FAQs
What is Retinitis Pigmentosa (RP)?
1
Retinitis Pigmentosa, or RP, is a group of inherited eye diseases that cause the light‑sensing cells in the retina to slowly stop working over time, leading to gradual vision loss. It usually starts with trouble seeing in low light and difficulty with peripheral vision (tunnel vision) before affecting central vision later on.
Is RP rare?
2
RP is considered a rare disease, affecting roughly 1 in 3,000 to 1 in 5,000 people worldwide. It can run in families in different ways, including autosomal dominant, autosomal recessive, and X‑linked inheritance patterns.
What does RP actually feel like day‑to‑day?
3
Most people with RP first notice problems seeing in the dark or in dim lighting, and over time their side vision narrows, making it feel like looking through a tunnel. As it progresses, it can become harder to spot obstacles, judge distances, and eventually to read or recognise faces without adjustments or tools.
What is the prognosis for someone with RP?
4
RP is progressive, which means vision generally gets worse over many years, but the speed and severity can vary a lot from person to person. Some people retain useful vision for most of their lives, while others lose significant sight earlier, depending on the specific genetic type and other factors.
Right now there is no cure for most forms of RP. However, there is an approved gene therapy (Luxturna) for a small subset of people with a specific RPE65 mutation, and there is active research into gene therapy, stem cells, and other treatments.

Is there a cure for RP?
Can RP be treated or slowed down?
6
While RP usually cannot be stopped or reversed, some people may benefit from approaches like carefully supervised vitamin A, sun protection, and treatment of complications such as cataracts or macular swelling. Low‑vision aids, orientation and mobility training, and workplace or home adaptations can also make a huge difference in independence and quality of life.
No—RP is a very mixed bag. Age of onset, speed of progression, symptoms, and how much vision remains can all differ widely, even between people in the same family.

Is RP the same for everyone?
Can people with RP still work, drive, or farm?
8
Many people with RP work, study, raise families, and, yes, even farm, but they often need to adapt how they do things as their vision changes. Driving usually becomes unsafe once peripheral or night vision drops below legal standards, but with planning, technology, and support, people with RP can keep doing a lot of what they love in different ways.
How can I support someone with RP?
9
You can ask how they prefer to be guided or helped, give clear verbal directions instead of vague pointing, and be patient if they miss visual cues. Advocating for accessible spaces, inclusive workplaces, and better public understanding of low vision also goes a long way.
