Retinitis pigmentosa is a group of inherited retinal degenerative diseases characterized by progressive loss of photoreceptor cell and pigment epithelial function.
Its typical symptom is night blindness, accompanied by progressive visual field defects.
Fundus pigmentation and significantly abnormal or no waveforms in electroretinogram are its clinical features.

The incidence of this disease is very low, and it is one of the important causes of blindness in fundus diseases.
To date, there is no effective treatment for retinitis pigmentosa.
