What are intravitreal injections?
Intravitreal injections are a route of drug administration locally in the posterior part of the eye.
In which cases do they apply?
Intravitreal injections are applied mainly in exudative amd, diabetic macular edema and diabetic retinopathy, in macular edema (a swelling of the macula due to accumulation of fluid) by injecting antiangiogenics or corticosteroids.
A complete ophthalmological examination will be necessary, including a fundus, an oct to see the retina and in some cases a fluorescein angiography to see the state of the retinal blood vessels.
The injection is performed under topical anaesthesia and usually does not cause discomfort. The eye and eyelids should be thoroughly disinfected before performing the procedure, as well as a topical antibiotic administered to the eye for a few days afterwards is sometimes needed.
Like any intervention, there are some risks associated with it, the most frequent being infection, although the risk is minimal if good prophylaxis is carried out.
