Dexamethasone Intravitreal Implant for the Treatment of Macular Edema and Uveitis: A Comprehensive Narrative Review

Kamal Kishore et al. Clin Ophthalmol. .

Abstract

Purpose: The purpose of this review article is to provide a comprehensive review of the current applications of intravitreal DEX implant (Ozurdex®, Allergan Inc, Irvine, CA) for a variety of ophthalmic conditions - ranging from FDA approved indications to off-label uses. We have attempted to provide relevant evidence from the literature to help a reader develop an understanding of the biological and pharmacokinetic properties of DEX implant, its uses, and potential side effects.

Methods: PubMed searches were performed using the terms "Ozurdex", or "intravitreal DEX implant", AND "retinal vein occlusion", or "diabetic macular edema", or "uveitis". The search was performed in July of 2021, with an additional search in October 2021. All original English language articles were considered for this review.

Results: DEX implant has evidence of efficacy in a variety of clinical situations including macular edema associated with retinal vein occlusion, diabetes, uveitis, and others. Safety concerns include cataract formation and progression, intraocular pressure elevation, complications related to intravitreal injection, and opportunistic infections secondary to steroid-induced immune suppression.

Conclusion: DEX implant is a useful tool in the management of several retinal disorders. Further studies are needed for head-to-head comparison with other treatment modalities and to determine its precise place in clinical practice.

Keywords: Ozurdex; diabetic macular edema; intravitreal DEX implant; retinal vein occlusion; uveitic macular edema; uveitis.
