Summary of important information

Contact your doctor as soon as possible if you experience any of the following symptoms after treatment with Ongavia:

  • Pain
  • Light sensitivity/ tearing
  • Swollen lids or other swelling
  • Light flashes
  • Seeing flies, black spots or coloured halos
  • Drying of the surface of your eye
  • Increasing redness
  • Blurred, distorted or sudden loss of vision

What is Ongavia?

In diseases such as RVO, abnormal blood vessels grow in the eye. These can leak and cause vision loss.

Ongavia contains ranibizumab as the active medicinal ingredient. Ranibizumab specifically recognises and blocks the action of new blood vessel growth in the eye, and in turn can help to stop leakage and vision loss.

Why have I been prescribed Ongavia?

You have been diagnosed with RVO.

  • RVO is a condition that affects the macula, a part of the retina at the back of the eye.
  • The macula is the area that lets you see sharply in the centre of your vision.
  • Blockage of a retinal vein can cause leakage of fluid into the retina and swelling of the macula. This may damage the retina and cause vision loss.
  • There are two types of RVO, central and branch, which are defined by the type of blood vessel that is affected:
    Branch RVO is more common than central RVO and is caused by obstruction of a tributary of the retinal vein. Only the part of the retina that is drained by the blocked branch is affected.
    Central RVO is caused by obstruction of the central retinal vein. Because the main vein in the eye is blocked, the entire retina is affected.

How is Ongavia treatment given?

Ongavia is given by your ophthalmologist (eye doctor) as an injection into the eye.
It is normal to worry about such injections, but usually the injection is virtually painless.

What will happen at my treatment appointment?

On the day of your treatment, care will be taken to make sure you are relaxed and comfortable.
Before receiving Ongavia, it is important to tell your doctor if:

  • You have had a stroke or experienced transient signs of stroke (weakness or paralysis of limbs or face, difficulty speaking or understanding).
  • You are taking or have recently taken any other medicines, including medicines obtained without prescription.
  • You have an eye infection.
  • You have any pain or redness in your eye.
  • You think you may be allergic to Ongavia, to other medicines with ranibizumab or to Betadine® (iodine).

Keeping your doctor informed will help them to decide whether Ongavia is the most appropriate treatment for you.

Prior to the treatment a doctor or nurse will:

  • Cover your face and the area around the eye with a special drape.
  • Clean your eye and the skin around it.
  • Hold your eye open so you do not blink.
  • Numb your eye with an anesthetic to prevent pain.

The doctor will then give the injection into the white part of your eye. You may feel a little pressure with the injection.

What will happen after I receive my Ongavia injection?

Your doctor will perform eye tests, such as measuring the pressure in your eye, to make sure the treatment went well.

The white area of the eye, where the injection is given, will likely be red.

  • This redness is normal and it will go away in a few days.

You may see a few spots or ‘floaters’ in your vision.

  • These spots are normal and should go away in a few days.

Contact your doctor if either of these symptoms do not go away or get worse.

Your pupils will be dilated for the injection, and this can make it difficult for you to see for a few hours after the treatment.

  • You should not drive until your vision has returned to normal.

It is important to monitor any changes in the condition of your eye and your overall well-being in the week following your injection.

Rarely, injections in the eye can cause infection.

What to do if I have side effects?

Contact your doctor as soon as possible if you have any of the following signs and symptoms in your eye:

  • Pain
  • Light sensitivity/ tearing
  • Swollen lids or other swelling
  • Increasing redness
  • Blurred, distorted or sudden loss of vision
  • Light flashes
  • Seeing flies, black spots or coloured halos
  • Drying of the surface of your eye.

If you notice any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in the package leaflet.

How long will I need to continue Ongavia treatment?

Every patient is different. It is likely that you will need additional Ongavia or other ranibizumab injections, but this will depend on how you respond to treatment and how your vision changes.

If you are considering stopping treatment with Ongavia, ask your doctor for advice first.
