Intravitreal Steroids in Diabetic Macular Edema.

Over the past decade, great strides have been made in the management of diabetic macular edema (DME). Therapeutic alternatives now include focal/grid laser photocoagulation, vitreo-retinal surgery, and intraocular injection of anti-angiogenic and steroid molecules. Intravitreal administration of steroids represents a fundamental alternative for recalcitrant and naive eyes with DME, especially in those cases when anti-vascular endothelial growth factor (VEGF) agents are contraindicated or a treatment regimen with fewer intravitreal injections is required. Currently, 3 intravitreal corticosteroid options for DME treatment are available: the dexamethasone delivery system, the fluocinolone acetonide insert, and off-label intravitreal triamcinolone acetonide. All 3 agents are associated with risk of cataract progression and intraocular pressure elevation, but they maintain a good safety profile. In patients who remain unresponsive to anti-VEGF therapy, are pseudophakic, at low risk for glaucoma, or who have significant cardiovascular risk, treatment with long-lasting intraocular steroids is suggested. There still remain many unanswered questions about intravitreal drugs, regarding dose, frequency, the correct regimen of each treatment, and the potential long-term side effects.
