About Intravitreal Injections
Intravitreal injections are drugs that are injected into the eye to reduce swelling and capillary growth. Usually, the drugs belong to the “Anti-Vascular endothelial growth factor” group of medicines, so the treatment may be referred to as “Anti-VEGF” treatment. However, in some cases, steroid drugs may be injected instead.
Conditions Treated with Intravitreal Injections:
- Macular degeneration (specifically Wet Age-related Macular Degeneration)
- Diabetic Retinopathy
- Retinal Vein Occlusions
Generally, any retinal condition caused by new blood vessel growth and fluid leakage may benefit from injections.
How it Works:
When the anti-VEGF drugs are injected into the eye, they stop the growth of new blood vessels. These new blood vessels are bad because they grow abnormally and bleed into the eye. In some retinal diseases, the blood vessel growth is controlled by a growth factor called VEGF. Anti-VEGF medicines interrupt this process, which should slow the growth and any associated swelling. Steroids are only used in patients that don’t respond to anti-VEGF drugs.
