[The value and application prospect of cyclosporine A in the treatment of dry eye].

Dry eye is the most common ocular surface disease, the core pathogenesis of which is ocular surface inflammation. Anti-inflammation is one of the important clinical treatments of dry eye. Since the definitely immunosuppressive effect, topical ophthalmic cyclosporine A (CsA) has been used in dry eye for many years. A large number of studies have been published in recent years, including its therapeutic effects, indications and applications. This article will introduce the mechanism of ophthalmic CsA, summarize its clinical treatment effects in dry eyes of different countries, different causes, and different severity. Meanwhile we will analyze the pros and cons and the applied prospects of ophthalmic CsA with various forms, and generalize the indications, treatment suggestions and safety of CsA used in dry eye, in order to provide references for the clinical applications.
