Pterygium
What is Pterygium?
A Pterygium is a wedge-shaped growth of the conjunctiva into the cornea ( the transparent part of the eye). It looks like an extra skin covering the side of the eye.
What causes Pterygium?
The exact aetiology of pterygium is not clear. As it occurs more often in people who live in the tropics, excessive ultraviolet light exposure from sunlight may be a factor.
What are the potential problems?
It usually does not cause any problem unless it becomes large. When this happens it may cover part of the cornea and interfere with one’s vision. It can also cause difficulties with contact lens wear or irritate the eye by giving it a foreign body sensation.
What is the treatment?
A Pterygium usually doesn’t require any removal unless it causes visual disturbance or discomfort. The removal is done as a day surgery. You may require regular follow up with your eye doctor to track its growth.
