Inheritance: Several different inherited retinal problems can cause retinitis pigmentosa (RP). In most cases, the disorder is caused by a recessive gene. This means that an abnormal gene must be inherited from both parents. Some cases have also been linked to genetic mutations on the X chromosome.

In the early stages of RP, rods are more severely affected than cones. As the rods die, people experience night blindness and a progressive loss of the visual field, the area of space that is visible at a given instant without moving the eyes.
