Pronunciation: IN-truh-VIT-ree-al in-JEK-shun
Direct injection of medication into the vitreous cavity of the eye for treating retinal diseases.
Full Definition
Intravitreal injection is a procedure involving the direct administration of medication into the vitreous cavity through the pars plana using a fine needle. This route of drug delivery allows for high local concentrations of medication while minimizing systemic exposure and side effects. Common indications include treatment of diabetic macular edema, age-related macular degeneration, retinal vein occlusion, and endophthalmitis. Medications frequently administered include anti-VEGF agents (ranibizumab, bevacizumab, aflibercept), corticosteroids, and antibiotics. The procedure is performed under sterile conditions in an office or ambulatory surgery setting with topical anesthesia.
