Causes & Treatment
What is a Pterygium?
A pterygium is a raised, triangular or wedge-shaped, harmless growth of tissue on the white of the eye (sclera). It usually occurs on the side of your eye nearest your nose.
A pterygium can continue to grow over the cornea (clear window at the front of the eye) in a
triangular fashion. It may grow large enough to affect your vision (eyesight).
What causes a Pterygium?
A pterygium usually develops if you have been living in a hot, dry climate.
It is thought to be a response to long-term sunlight exposure and chronic irritation from the dry climate.
What are the symptoms of a pterygium?
A pterygium can cause grittiness, itchiness, burning, irritation, redness and tearing.
If the pterygium continues to grow towards the centre of the cornea it can affect your vision.
How is a pterygium treated?
Treatment depends on the symptoms.
If the pterygium is small and/or growing, eye-drops may be used to relieve any redness or irritation.
Surgical removal of a pterygium is performed:
– if there is persistent or recurrent redness or irritation despite using drops
– if it alters the shape of the cornea and/or affects vision
– if it is cosmetically unappealing
During your consultation, you will have a complete assessment of your eye including the extent of the pterygium. You may also have scans done to determine the depth of the pterygium and its affect on the shape of your eyeball. Depending on the results of assessment, Mr. Ayoub will discuss the best treatment option for you.
