A pterygium is generally the abnormal growth of tissue on the white part of the eye closest to the nose. This abnormal tissue is usually pink in colour and can grow so that it covers the cornea.
Excessive exposure to UV light is the main reason for the growth of this abnormal tissue.
A pterygium may cause irritation, a gritty or itchy sensation to the eye and in some cases a decrease in vision. If the pterygium grows too close to the cornea or if it is causing too much irritation, an Ophthalmologist can perform an operation to remove it.
If you think you have a lesion similar to the ones below, please see your GP or Optometrist for a referral to an Ophthalmologist.
