Intravitreal Dexamethasone Implant in the Treatment of Non-Infectious Uveitic Macular Edema.

Macular Edema (ME) is a common complication, leading to severe vision loss in patients with Non-Infectious Uveitis (NIU). The treatment of uveitic ME is still very challenging for many ophthalmologists. Various agents, such as corticosteroids, anti-vascular endothelial growth factors, and immune-modulators, have been used for combatting uveitic ME. However, there is not enough evidence to support the efficacy of any of these agents. Intravitreal Dexamethasone Implant (IDI) (Ozurdex; Allergan Inc, Irvine, CA) is a widely administered corticosteroid for the long-term management of uveitic ME in certain cases. Ophthalmic implant is made up of a biodegradable copolymer that contains glycolic acid and lactic acid. Recent studies have demonstrated that dexamethasone implant effectively improves uveitis-related ME. The authors suggest that this effect could be sustained for at least six months with close monitoring and re-treatment, as needed. The current study reviewed major clinical studies about IDI in eyes with NIU and briefly overviewed their results.
