Treatment:

No treatment is required unless the pterygium begins to block vision -- then it should be removed with surgery. Wear protective glasses and a hat with a brim to prevent the condition from returning.

Expectations (prognosis):

Most pterygia cause no problems and do not need treatment. If a pterygium affects the cornea, results are usually good after it is removed.

Complications:

A pterygium can return after it is removed.

Calling your health care provider:

People with pterygium should be seen by an ophthalmologist each year, so that the condition can be treated before it affects vision.

Call for an appointment with your ophthalmologist if you have had a pterygium in the past and your symptoms return.
