Intravitreal Injections

An intravitreal injection is a method of delivering medication inside the eye to treat a variety of conditions.

Injections allow medications to be delivered at high doses straight to the area of need without dangerous side effects to the rest of the body. 

Intravitreal injections have revolutionised the management of macular degeneration, retinal vein occlusions and diabetic eye disease. 

Intravitreal injections are usually performed in an outpatient clinic setting under sterile conditions. Local anaesthetic is used during the procedure to numb the eye and topical antiseptic solution is also used to clean the eye prior to the injection. Patients do not feel pain and can't see the needle!

The injection is given through the white part of the eye, usually hidden underneath the eyelid. There may be some redness immediately afterward, and a gritty sensation. This usually settles overnight.

Patients may also experience a few floaters in the first 24 hours after an intravitreal injection.
