Anti-Vascular Endothelial Growth Factor (anti-VEGF) The most common reason<unk>  injections are used is to administer anti-vascular endothelial growth factor (anti-VEGF) therapies to treat wet age related macular degeneration (AMD) and diabetic retinopathy. Both of these conditions cause damage to the retina leading to vision loss. There are three widely used Anti-VEGF drugs to treat these conditions: ranibizumab (Lucentis®; Genentech), bevacizumab (Avastin®; Genentech), and aflibercept (Eylea®; Regeneron Pharmaceuticals). Bevacizumab has not been FDA approved to treat wet AMD however in the US it is the first line anti-VEGF therapy for over half of ophthalmologists due to its efficacy and drastically lower cost. These three drugs bind to VEGF molecules preventing them from binding to VEGF receptors on the surface of endothelial cells thereby stopping the abnormal angiogenesis that causes wet AMD. All three of these therapies have vastly improved outcomes for sufferers who had limited treatment options prior to their invention but must be administered via<unk>  injection. Steroids Steroids may be administered via<unk>  injection to treat diabetic and vasculo-occlusive macular edema, exudative macular degeneration, pseudophakic cystoid macular edema, and posterior uveitis. Common steroids used to treat these conditions include dexamethasone and triamcinolone acetonide (Triescence, Alcon Laboratories, Inc.). Steroid implants, such as the dexamethasone implant (Ozurdex, Allergan, Inc.), are used for long-term treatment of macular edema. Both of these steroid work by modulating inflammatory cytokines.
