At what age does retinitis pigmentosa occur?
RP is typically diagnosed in young adulthood, but the age of onset may range from early childhood to the mid 30s to 50s. Photoreceptor degeneration has been detected as early as age of six years even in patients who remain asymptomatic until young adulthood.
Do all people with retinitis pigmentosa go blind?
Does everyone with retinitis pigmentosa go blind? There are many different types of retinitis pigmentosa, and not all of them cause a total loss of vision. The best way to keep and use as much vision as possible is to have regular eye examinations and follow the doctor’s advice.

Is a bionic eye possible?
Currently, retinal implants are the only approved and commercially available bionic eyes, though cornea transplants and cataract surgery can replace the cornea and lens if these structures are clouded or are incapable of focusing light for other reasons.
Do rods see color?
Rods don’t help with color vision, which is why at night, we see everything in a gray scale. The human eye has over 100 million rod cells. Cones require a lot more light and they are used to see color. We have three types of cones: blue, green, and red.
Can you have retinitis pigmentosa in one eye?
Retinitis pigmentosa (RP) represents a group of hereditary progressive retinal disorders. It affects approximately 1.5 million people worldwide. Retinitis pigmentosa usually affects both eyes symmetrically, although in some cases, it affects one eye more than the other.
Why do you see faint light better in the periphery of your vision than in the center?
Around the centre of the retina are so-called cone cells, which give us colour vision and need good light levels. Looking off to one side allows more light from faint objects to strike the rod cells, and become visible to us.
How do you test for retinitis pigmentosa?
A series of tests are available to confirm a diagnosis of RP. These include: Dilated Eye Exam During a dilated eye exam, you are given special eye drops to dilate your pupils, allowing your ophthalmologist to clearly see the retina at the back of your eye.
