Systemic lupus erythematosus scleritis (SLE) is an autoimmune disease of unknown etiology involving multiple system organs and characterized by the production of anti-cellular antibodies, cytoplasmic and cell membrane antigen antibodies. Systemic lupus erythematosus is more common in young women, with a male-to-female ratio of at least 1:7 to 1:9. The age of onset is mostly 15 to 45 years old, but it is also seen in children and the elderly. The incidence of SLE in blacks in the United States is about three times that of whites, and the incidence of SLE in the general population is 15.5/100,000 to 50/100,000 population. The prevalence in China is higher than that in Western China, about 70/100,000 population, and the prevalence is also high in Chinese populations in the United States, Singapore, etc., which may be related to genetic factors. The prevalence in different regions and different ethnic groups in China is also different. The epidemiological data of systemic lupus erythematosus scleritis are unknown.
