Dry eye syndrome is a common autoimmune deficiency disease that mainly affects the exocrine glands, including the lacrimal and salivary glands, causing dry eyes and mouth. Clinically, patients present with reduced salivary and tear secretion, which manifests as dry eyes and mouth. Dryness syndrome is a systemic disease, and organs outside the gland such as respiratory tract, digestive tract, kidney, muscles, joints and blood vessels may be involved, resulting in various clinical manifestations. Dry mouth, multiple caries, mumps and other symptoms due to salivary gland lesions are called dry mouth syndrome. The symptoms such as dry eyes, foreign body sensation and less tears due to the decrease of mucin secreted by lacrimal gland due to the involvement of lacrimal gland are called ocular dryness. Dry syndrome can exist alone or occur in another autoimmune disease with clear diagnosis, such as systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, etc. The former is called primary dry syndrome and the latter is called secondary dry syndrome.
