Sphingolipid metabolism is widely involved in the functional regulation of different cells, and also plays an important role in ocular tissues.Sphingosine 1-phosphate (S1P) is the end product of sphingolipid metabolism and has been shown to play an important role in the onset and development of eye diseases.S1P signaling pathway is widely expressed in various ocular cells and is involved in the regulation of cell proliferation, differentiation, migration and apoptosis.S1P activates a variety of signaling pathways by binding to corresponding receptors and thus plays a wide range of physiological and pathological effects in the eye.Recent studies have found that the S1P signaling pathway can not only mediate the normal development of blood vessels and nerves in the eye, maintain the normal structure of the ocular tissues, and participate in the metabolism of lipids in the eye, but also has a close relationship with immune-related inflammatory response, pathological fibrosis, destruction of cell functional barrier and other related pathological changes.This paper mainly reviewed the basic overview of the S1P signaling pathway, its physiological role in the eye, and its role in the pathological changes of anterior and posterior segment diseases, so as to provide new directions and targets for the treatment of eye diseases.
