Intravitreal injections are a treatment for many retinal eye conditions where there are abnormal vessels growing under the retina e.g certain types of wet AMD. It's also a treatment for conditions that cause swelling at the macula. They may also be used in cases of inflammation and infection at the back of the eye. After applying an anaesthetic to the front of the eye, the injection is delivered around 3 to 4mm from the edge of the cornea. The contents of the injection are delivered into the vitreous cavity inside the eye. You may be asked to take antibiotic eye drops after the procedure. A common symptom after the injection is the presence of a dark spot or small floaters. In addition, your eye pressure will be moderately elevated. You may also experience a transient decrease in vision and discomfort following the treatment. However, if you are in pain, or if you notice that vision has decreased significantly, you should contact your doctor immediately.
