Intravitreal injections are commonly used to treat retinal diseases such as diabetic retinopathy, macular degeneration, and retinal vein occlusion. Intravitreal injections are a very effective and minimally invasive procedure. Common injections used are anti-VEGF therapies (Avastin, Eylea, Lucentis) that can reduce swelling in the macula and suppress the growth of abnormal blood vessels, preventing further vision loss. Many of these injections are given on a continual basis. Other injections may include corticosteroids (Dexamethasone, Ozurdex, Triesence, Triamcinolone, Kenalog) to reduce inflammation and treat conditions such as macular edema.
This procedure is done in-office and only requires topical anesthesia. The eye is cleaned with an antiseptic solution, and then the eye is held open with a wire speculum. The medication is injected directly into the eye. Patients may experience some slight discomfort after treatment and may see floaters in their vision for a few days.
