Intraocular injections are commonly used to treat retinal diseases such as diabetic retinopathy, macular degeneration and retinal vein occlusion. These diseases often cause blindness and should be treated as early and as thoroughly as possible. FDA-approved medications such as Eylea, Lucentis, Avastin or Macugen are injected directly into the eye to help patients maintain their baseline vision and keep vision loss at a minimum. Many patients often see an improvement in their vision from these injections as well.
