A pterygium is a non-cancerous, painless, fleshy growth on the white of the eye, usually caused by UV exposure (sunlight). It can remain small or grow large enough to cover part of the cornea, affecting vision.

An Overview: Pterygium

At a Glance:

  • Growth of abnormal tissue and blood vessels on the white of the eye
  • Almost always caused by sunlight exposure
  • Can remain small and require no treatment
  • If it grows to cover part of the cornea, surgery is the recommended treatment

By far, the most common cause of pterygium is exposure to sunlight, particularly if other irritants such as dust or saltwater are involved. It is so commonly associated with these three factors that it has earned the nickname “surfer’s eye.” 

Patients opt to remove a pterygium if it affects their vision or for cosmetic reasons. While non-surgical treatments exist and some small growths may never require treatment, the only way to get rid of pterygium permanently is through surgery.

Pterygium Surgery

When a pterygium distorts vision, grows large, demonstrates continued growth, or causes ongoing irritation, surgery is required. Pterygium surgery is painless, occurs under local anesthesia only (patient is awake), and usually takes about 30 minutes.

The most common form of surgery involves removing the pterygium and then taking a portion of the conjunctiva (the membrane that covers the white of the eye) to cover the space left behind. See our Pterygium Surgery page for more details.
