Intravitreal injection of medication

An intravitreal injection is a procedure in which medication is delivered directly into the vitreous body of the eye.

It is used in the treatment of a number of retinal and choroidal conditions and makes it possible to achieve the required concentration of the drug directly in the tissues of the eye.

The need for the procedure, the medication and the number of injections are determined by the ophthalmologist.

Which conditions is it used for?

Intravitreal injections may be used for:

  • age-related macular degeneration
  • diabetic macular oedema
  • retinal vein occlusion
  • other conditions involving oedema or abnormal growth of blood vessels

The indications are determined by the ophthalmologist after an assessment.

How is the procedure performed?

Before the injection the doctor examines the patient and confirms the indications. The procedure is carried out under sterile conditions with local anaesthesia.

Afterwards the ophthalmologist assesses the eye and gives recommendations.

How many injections are needed?

The number depends on the diagnosis, the medication and the response to treatment. The schedule is set by the doctor and may be adjusted following review appointments.

After the procedure

Follow the ophthalmologist’s recommendations and do not use any additional eye medication without agreeing it with your doctor.

If severe pain, marked redness, a sudden drop in vision or flashes of light occur, seek medical help urgently.
