What does it involve?

Intravitreal injections are used to locally administer medication to treat the secondary complications of diabetic retinopathy.

When is it carried out?

The treatment is mainly indicated for diabetic macular oedema (accumulation of fluid in the macula), in which corticosteroids or anti-angiogenic drugs are administered intraocularly.

Prior examination

Examination of the eye and fundus. In most cases, an OCT test is performed, and, in some cases, a fluorescein angiogram is also indicated.

Before the surgery

Before the injection, the eye and eyelids are disinfected. After the injection, antibiotic eye drops have to be administered for a few days.


The injection itself is a short procedure. It can be carried out in theatre or in the doctor’s surgery, but always under strict asepsis conditions. It is performed under topical anaesthesia (eye drops) and does not generally cause discomfort.


As in all surgical interventions, the greatest risk is eye infection. If the correct prophylactic measures are employed, however, the risk is minimised (much lower than after cataract surgery, for example).
