Retinitis pigmentosa is an eye disease characterized by degeneration of the retinal pigment epithelium, with progressive vision loss and night blindness as the main clinical manifestations. Retinitis pigmentosa is a degenerative disease that is mostly hereditary and has multiple modes of inheritance. Patients mainly present with chronic progressive visual field loss, night blindness, pigmentary retinopathy and electroretinographic abnormalities. In its early stages, retinitis pigmentosa leads to night blindness and loss of dark adaptation, which can eventually lead to vision loss. Retinitis pigmentosa should be detected and treated as early as possible, especially for people with high prevalence of the disease. Regular checkups of vision and fundus should be conducted, and treatment should be given once symptoms appear to avoid further aggravation of the disease. Patients with retinitis pigmentosa are advised to seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
