This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.
If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.
You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.
Related diseases are conditions that have similar signs and symptoms. A health care provider may consider these conditions in the table below when making a diagnosis. Please note that the table may not include all the possible conditions related to this disease.
Conditions with similar signs and symptoms from Orphanet
Besides non syndromic forms, there are syndromic forms of RP of which the most frequent are Usher syndrome (RP and deafness) and BardetBiedl syndrome (RP and metabolic impairment). RP is to be distinguished from macular dystrophies (peripheral visual field is normal) and Leber congenital amaurosis (congenital retinal dystrophy) (see these terms).

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.

My father and his two brothers are suffering from RP. Now I have a fear that RP is a genetic disease. At this time I am not affected with RP. My dad said it affected him at the age of 35. Now I need clarity that if I get married and have children, will RP affect them? I had consulted a genetic doctor and they are saying that it may or may not affect them. If so, I will try to avoid children. See answer
My sister has retinitis pigmentosa. Can this condition be cured? See answer
How can one anticipate the progression of their disorder, as in how bad their condition is? How does one know what type of retinitis pigmentosa they have if their condition is inherited, developed in childhood, and their parents don't have it? See answer
I have peripheral vision loss, but not night blindness. After a retinal exam, my doctor told me that I have retinitis pigmentosa (RP). Is X-linked congenital stationary night blindness (XLCSNB) a form of RP or a completely different disease? I read that in the incomplete form of XLCSNB, the damage is stationary and the patient may not have night blindness. Is it possible that I am in this group? See answer
How is gene therapy being used to treat conditions like retinitis pigmentosa? Does gene therapy involve transplanting healthy human eye cells in the diseased retina? How can I learn more about clinical trials and research studies investigating new treatments for retinitis pigmentosa? See answer
Where can I find information on National Institutes of Health (NIH) funding for rare diseases, specifically retinitis pigmentosa? I am also looking for information on the cost of having this condition and current research projects. How many people have retinitis pigmentosa in the United States? See answer
