Uveitis is a type of ocular inflammatory disease caused by various etiologies, for which corticosteroids are the main treatment. Dexamethasone Intravitreal implant (DEX-I) has been widely used in the treatment of uveitis across the world. Then, new indications and complications appeared. This review aims to summarize the use of DEX-I in uveitis in the past 10 years.

We summarized the clinical data (baseline characteristics, efficacy and safety) and discussed controversies by retrospectively analyzing the articles and cases published in PubMed and Web of Science using the terms “Ozurdex”, OR “intravitreal dexamethasone implant”, AND “uveitis” from 2010 to 2022.

DEX-I is effective in reducing edema, improving inflammation and improving vision when treating various conditions of uveitis including infectious, no-infectious, pediatric uveitis, and surgery-related applications. The efficacy of DEX-I as a monotherapy is related to the following: etiology and course of disease, treatment of systemic diseases, patients’ toleration after multiple injections, economic situation, etc. In addition, intravitreal corticosteroids implantation may replace systemic therapy in some patients. In terms of safety, the incidence of high intraocular pressure is about 20.52%, and the incidence of cataract is about 15.51%.

DEX-I can effectively treat non-infectious uveitis and some infectious uveitis such as suspected tuberculosis, and its safety is controllable. Further studies are necessary to evaluate the effect of monotherapy and to expand more indications.
