What does it involve?
Intraocular injections are a way of administering a drug into the eye locally and in a concentrated form. In the case of uveitis, the intraocular injection of anti-inflammatories (especially corticosteroids) is often used to control inflammation, while avoiding the side effects associated with the systemic administration of corticosteroids.
When is it carried out?
The main indication for intraocular corticosteroids is the treatment of macular oedema secondary to intraocular inflammation.
Examination of the eye and fundus. In most cases, an OCT test is performed, and, in some cases, a fluorescein angiogram may also be necessary. In the case of uveitis, it is important to check for the presence of an intraocular infection before administering the corticosteroid intraocularly.
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).
