Pterygium

Pronounced ‘ter-ig-ium’, this is a benign growth of tissue that develops on the conjunctiva, the clear tissue covering the white part of the eye, and may extend onto the cornea.

What happens first?

Symptoms

Pterygium often appears as a raised, wedge-shaped bump with a pinkish appearance. It may have blood vessels and can be visible on the eye. Pterygium is associated with prolonged exposure to UV light, wind, dust and other environmental factors. People who spend a lot of time outdoors are more prone to pterygium. A pterygium may have very few symptoms initially but as they grow, it can lead to symptoms such as:
  • Redness
  • Irritation
  • Dryness
  • Feeling of a foregin body in the eye
  • Prolonged growth of pterygium will eventually obscure vision.
If it extends to the cornea then it will also affect vision.

Treatment options

Surgery

Surgery is an option for treating more serious cases that affect vision or create treatment-resistant symptoms. Some people may also opt to undergo the surgery for aesthetic reasons. The procedure is usually carried out using local anaesthetic. Precision instruments are used to remove the pterygium tissue. Healing can be encouraged in a variety of different ways — often a portion of your own conjunctiva is used to cover the area in a process called auto-grafting.

Examinations

Pterygium surgery is a surgical procedure performed to remove a pterygium, which is a fleshy growth that can develop on the conjunctiva.

During the procedure, the surgeon will first numb the eye with local anaesthesia. The pterygium is then carefully removed. To prevent a pterygium returning, a technique called conjunctival autografting may be used. In this technique, a small amount of healthy tissue is taken from elsewhere in the eye and is transplanted into the area where the pterygium is. This helps to protect the exposed area, reducing the risk of recurrence.

After surgery, you may feel some discomfort, tearing, and sensitivity to light. It is important to follow the post-operative care instructions provided by the Regency Eye Hospital.
