What is a Pterygium?

A pterygium is the result of damage to the surface of the eye due to ultraviolet (or UV) light exposure that occurs over years. This damage affects the conjunctiva, which covers the sclera or white of the eye. In response to this damage, the conjunctiva tries to heal by growing over itself. This is seen as a pink triangle of tissue that starts on the white of the eye (usually the side closest to the nose) and can grow over the clear cornea towards the centre of the eye. This may take many years.

What are the symptoms of a pterygium?

A pterygium may not cause any symptoms. As the pterygium becomes more prominent, it may cause grittiness and irritation as it disturbs the smooth surface of the eye. Occasionally, dry or cold weather can cause inflammation with the pterygium becoming red and sore.

If the pterygium grows onto the cornea, it may affect vision by causing scarring or changing the shape of the cornea. This may cause your vision to become either blurred or distorted. In extreme cases, a pterygium may grow into the line of sight and severely decrease the vision.

How can you treat a Pterygium?

Irritation and grittiness from the pterygium may be treated with artificial tear supplements as these lubricate the surface of the eye. If inflammation is present, a short course of steroid or non-steroidal anti-inflammatory drops can be used.

Surgery is recommended if the pterygium affects your quality of life by decreasing your vision or causing you regular discomfort. Surgical treatment can also be performed if the pterygium continues to get larger or you are concerned about its appearance.

What is involved in Pterygium Surgery?

Mr Darcy follows the latest surgical evidence for pterygium removal. This involves microsurgery to meticulously dissect the pterygium from the surface of the eye. A patch of healthy conjunctiva from under the upper eyelid is then transplanted onto the bare area on the surface that is left after the pterygium is removed. This graft helps with quicker healing, a better cosmetic result, and preventing recurrence.

Pterygium surgery is performed as a day surgery under local anaesthetic. The procedure takes approximately 30 minutes. We are happy to discuss answer any questions that you may have about this procedure and go through the benefits and risks of the treatment with you.

Where will I have my Pterygium surgery?

I operate at the Nuffield Health Bristol Hospital.

How long is the recovery after Pterygium surgery?

Following surgery, your eye will be uncomfortable for a few days while the surface of the eye heals. It may be blood-shot initially and this will improve over the recovery period. You will be given antibiotic and anti-inflammatory drops to prevent infection and help with healing.
