For many retinal diseases the only way to get medication to where it is needed is to give an injection into the eye. Eye drops and pills do not deliver a high enough amount of medication to the retina. Injections are the most efficient and safe way of treating many diseases including wet macular degeneration.
Typically intraocular injections don’t hurt. The most common sensation is a slight burning sensation that is related to the antiseptic used to clean the surface of the eye.
If you need an injection of medication drops will be put in the eye to numb the eye and minimize discomfort from the procedure. The eye is carefully cleaned with an iodine solution to reduce the risk of infection. The injection is given using a tiny needle that enters the eye through the white part of the eye (sclera) close to the front of the eye. The procedure is done in operation theatre to reduce the chances of infection.
An intraocular injection is generally a very safe procedure. Occasionally side effects can occur, most minor. Commonly, a spot of bleeding may develop on the surface of the eye at the site of the injection. The bleeding is painless and usually causes no symptoms at all, resolving over a few days. There is a very small risk of infection which happens in about 1 out of every 3,000 injection patient, which is again taken care by stringent sterilization measures taken during the procedure at our state of the art OT.
