Retinitis pigmentosa (RP) refers to a group of diseases that affect the retina and lead to the degeneration of retinal function. Retinitis pigmentosa is a rare hereditary eye disease. This disease is characterized by chronic and progressive retinal degeneration and may eventually lead to blindness. In some patients, retinitis pigmentosa is a dominant inheritance. As long as one parent carries the pathogenic gene, the child will get sick. There are also some patients whose retinitis pigmentosa is linked. Only when the mother carries the disease-causing gene can the child get sick. Other cases were accompanied by hearing loss. This type of retinitis pigmentosa is more common in men.

Patients with recessive inheritance of the disease have early onset, serious illness, rapid development and poor prognosis. By the age of 30, the visual function has been highly impaired, and by the age of 50, it is almost completely blind. However, patients with dominant genetic type occasionally tend to be static after developing to a certain extent, so the prognosis is relatively better than that of recessive genetic type. So, we can wait until we have a chance to go to school and get a job. Most of the recessive inheritors of this disease have a history of joint smoking by close relatives, and banning joint smoking by close relatives can reduce the incidence of this disease by about 22%. In addition, patients with recessive inheritance should try to avoid marrying people with family history of the disease, let alone those with the same disease. The risk of children of patients with dominant inheritance is 50%.

It can be seen that this disease is not optimistic, and you are a close relative, so I suggest that you'd better go to the hospital and have a professional diagnosis and treatment at an ophthalmologist with better technology.
