Intravitreal injections are a common treatment for various eye conditions, such as age-related macular degeneration (AMD), diabetic retinopathy, and macular edema. During the procedure, a small amount of medication, typically an anti-vascular endothelial growth factor (anti-VEGF) drug or a corticosteroid, is injected into the vitreous cavity of the eye using a fine needle. This targeted delivery allows the medication to reach the retina and macula directly, where it can reduce swelling, inflammation, and abnormal blood vessel growth, thus preserving or improving vision. Intravitreal injections are usually performed in an outpatient setting and may require multiple treatments over time for optimal results.
