Eye injections deliver medications to the inside of your eye. The medications are placed in the vitreous (the gel-like fluid filling your eye) near the retina (at the back of your eye). The benefit of an eye injection is that it delivers a specific dose directly to the damaged tissues.
Retina Consultants of Austin may recommend eye injections for:
AMD occurs when the macula (an area in the center of your retina) thins out, damaging specialized cells needed for sharp, clear vision. You can develop two types of AMD, dry and wet, but eye injections are only used for wet macular degeneration.
Wet macular degeneration occurs when abnormal blood vessels develop. These weak vessels leak blood and fluids, causing swelling that damages the macula.
High blood sugar damages small blood vessels in your eye, resulting in diabetic retinopathy and diabetic macular edema.
Diabetic retinopathy causes blood vessels in your retina to swell and leak, leading to the same abnormal blood vessel growth as AMD. Diabetic macular edema develops when the fluids build up, causing swelling that damages the macula.
The veins in your retina may become blocked (occluded) due to a blood clot. This leads to fluid leaking from the veins and into your retina.
Eye injections typically contain one of two medications:
Anti-VEGF drugs stop the production of abnormal blood vessels. This reduces your risk of bleeding and retinal damage.
You may need more frequent injections at the start of your treatment. Some people may be able to stop anti-VEGF injections; others will need to keep getting them to prevent vision loss.
Your provider may inject corticosteroids alone or together with anti-VEGF medications. Corticosteroids reduce retinal swelling and inflammation.
Before your injection, your Retina Consultants of Austin provider puts numbing medication in your eye. Then, they clean your eye with an antiseptic to prevent infections and use a very small needle to inject the medication.
After your injection, your eye may feel slightly irritated (due to the antiseptic) and you may see floating air bubbles. These side effects go away in a few days.
