Intravitreal injections (IVT)

Intravitreal injection, or IVT , is a targeted treatment in which medication is administered directly into the vitreous inside the eye. This allows treatment to act very close to the retina and macula, exactly where the problem is located, with a precision that systemic treatments cannot provide. It is now a cornerstone in the management of many retinal diseases.

Important to know: Treatment is not the same for everyone. The frequency and duration of injections are adapted to each eye and each disease.
Purpose Targeted treatment of the retina
Principle Medication injected into the vitreous
Key point Regular treatment and personalized follow-up

Why is an intravitreal injection proposed?

Certain retinal diseases cause edema, inflammation, or the formation of abnormal blood vessels. By injecting medication directly into the eye, treatment provides rapid and localized actionwith a direct effect on vision and disease progression.

  • Age-related macular degeneration (AMD): Control neovascularization and preserve central vision.
  • Diabetic retinopathy: Reduce macular edema and inflammation.
  • Retinal vein occlusions: Limit swelling of the macula.
  • Other conditions: Depending on examination findings, imaging, and progression.

How is an injection performed?

An intravitreal injection is a quick procedure performed under strict sterile conditions. The eye is numbed with drops and then disinfected. The injection itself takes only a few seconds. The patient does not see the needle enter the eye, and pain is generally minimal.

  • Local anesthesia: With eye drops, without an injection around the eye.
  • Disinfection: An essential step to prevent infection.
  • Injection: A very brief procedure, felt differently by different patients.
  • Check: Immediate assessment after the procedure.
Is the injection painful?

Most patients mainly report temporary discomfort or a sensation of pressure. Significant pain is rare and short-lived.

After the injection: what is normal and what is not?

In the hours afterwards, the eye may be slightly red or sensitive. A mild gritty sensation is common and disappears quickly. Follow-up is used to assess treatment effectiveness and decide on subsequent injections.

  • Mild redness: Common and temporary.
  • Fluctuating vision: Possible for a few hours.
  • Rapid return to activities: Everyday activities are often possible the following day.
  • Seek emergency care if you experience: significant pain, sudden loss of vision, or persistent intense redness.
Regular check-ups are essential because they allow treatment to be adjusted and visual results to be optimized.

Frequently asked questions

Why are several injections sometimes necessary?

Some diseases are chronic. Injections control disease activity, but the effect of a single session is not always permanent.

Can I drive after the injection?

It is preferable to come accompanied on the day of the injection. Driving is generally possible the next day, depending on your visual comfort.
