Pterygium: Symptoms and Causes
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 (the 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 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
– It alters the shape of the cornea and/or affects vision
– It is cosmetically unappealing
