Primary retinitis pigmentosa (RP) is a group of genetic eye diseases that are dystrophic degenerative lesions of photoreceptor cells and pigment epithelium (RPE). It is characterized clinically by night blindness, progressive visual field reduction, pigmentary retinopathy and photoreceptor malfunction (ERG examination). The disease is inherited in several ways, either sex-linked recessive, autosomal recessive or dominant, or disseminated. The disease usually develops in both eyes, and in rare cases, in one eye. The onset of the disease is usually before the age of 30, most commonly in childhood or adolescence, with symptoms worsening in adolescence, and blindness in middle age or old age due to severe visual impairment from macular involvement. The degree of visual impairment and the rate of progression are related to the type and location of the mutated gene, and cannot be determined at all. How to treat retinitis pigmentosa Retinitis pigmentosa is a congenital hereditary disease, the symptoms are mainly night blindness and gradually declining visual acuity, some of the disease is relatively stable, there is no special treatment method, there are cases of advanced non-photoreceptor retinitis pigmentosa patients using artificial vision chip implantation to obtain partial vision, but it has not been clinically applied. Suggestions: retinitis pigmentosa cannot be cured, medication may delay the disease, you can take oral vitamin A, vitamin E, lutein, etc. as appropriate.
