How do I know if I have retinitis pigmentosa?
Retinitis pigmentosa (RP) is an eye disease. It leads to gradual loss of vision and, sometimes, blindness. RP occurs when the light-sensing cells in the eye break down. These cells, called rods and cones, are located in the retina. This is the back portion of the eye that receives light coming into the eye, and sends that visual information to the brain.

How to tell if you have retinitis pigmentosa?
An eye doctor ( ophthalmologist) can tell you if you have retinitis pigmentosa. They’ll look into your eyes and do some special tests: 1 Ophthalmoscope: The doctor will put drops into your eyes to make your pupil wider to get a better look at your retina. They will use a handheld tool to look into the back of your eye. If you have RP, there will be specific kinds of dark spots on your retina. 2 Visual field test: You’ll look through a tabletop machine at a point in the center of your vision. While staring at that point, objects or lights will appear to the side. You’ll press a button when you see them, and the machine will create a map of how far to the side you can see. 3 Electroretinogram: The eye doctor will put a film of gold foil or a special contact lens on your eye. Then they will measure how your retina responds to flashes of light. 4 Genetic test: You'll submit a DNA sample to find out which form of RP you have.
When does retinitis pigmentosa start?
Retinitis pigmentosa usually starts in childhood. But exactly when it starts and how quickly it gets worse varies from person to person. Most people with RP lose much of their sight by early adulthood. Then by age 40, they are often legally blind.

How to diagnose RP?
RP can be diagnosed and measured by: 1 Genetic testing. This test looks at a sample of your blood or other tissues to see if you have certain genes that are associated with a disease. It can also help determine the likely course or severity of a disease and whether gene therapy to replace the faulty gene may be helpful. 2 Electroretinography. This test measures the electrical activity in the retina, or how well the retina responds to light. It works much like the EKG, which measures the activity and health of the heart. 3 Visual field testing. RP can affect your peripheral (side) vision. Visual field testing helps measure your side vision and find any blind spots that may be developing. 4 Optical coherence tomography. Also known as OCT, this imaging test takes special, highly detailed pictures of your retina. It can help diagnose RP and find out how it is affecting your retina.
