An intravitreal injection is a procedure in which a medication is injected into the eyeball with a very fine needle. This allows for medication to be delivered directly into the eye for maximum benefit. It can be done in the clinic or operating theatre, and admission to hospital is not necessary.
Intravitreal injection therapy has become the standard treatment for a range of serious retinal diseases. It is highly effective for diabetic retinopathy & maculopathy, age-related macular degeneration and retinal vein occlusions, etc. However, multiple injections may be necessary to keep the condition under control.
How is the procedure performed?
Eye drops are instilled in the eye just before the injection to numb the eye. The eye and the surrounding area will then be cleaned with an antiseptic agent.
During the procedure, the eye lids will be gently kept open with an instrument and you will be given instructions to look in a specific direction during the injection. The injection is done with a tiny needle, on the white of the eye (sclera).
In some cases, another tiny needle may be used to withdraw some fluid from the front of the eye to normalize the eye pressure. At the end of the procedure, antibiotic eye drops will be instilled.
Drugs are injected directly into the eye to effectively treat a range of diseases affecting the retina.
Medication used
The drugs used are Lucentis (Ranibizumab), Eylea (Aflibercept), Avastin (Bevacizumab) and Ozurdex (Dexamethasone). All have proven to be effective in preventing loss of vision. Your eye doctor will discuss with you the best medication for you. The choice of medication will depend on the condition being treated, general health status and individual responses to the medication.
