Understand Symptoms and Signs Used for Diagnosis

• 1

  Realize the main symptom to diagnose a pterygium is the change in the white tissue between the cornea and the corner of the eye. The tissue may become raised and change to a reddish-brown color.

• 2

  Recognize most routine ophthalmic evaluations reveal asymptomatic (without symptoms) patients who are concerned about the appearance of the extra tissue growth.

• 3

  Find some patients present with a vascularized (red and inflamed) pterygium.

• 4

  Note irregular corneal warpage in some individuals which leads to diminished visual acuity. A noticeable decrease in vision may be motive for some patients to seek medical attention.

• 5

  Expect symptoms of dry eye syndrome to help diagnose pterygium.

• 6

  Recognize the difference in criteria to diagnose a pinguecula (a yellow spot associated with aging). A pinguecula is a calcium or protein deposit which makes a change in the conjunctiva similar to a skin callus.

Learn Causes of Pterygium

• 7

  Realize that patients who spend a lot of time outdoors in warm, dry climates (such as near the equator) are more susceptible to developing a pterygium.

• 8

  Observe allergens and irritants such as air pollution, chemicals, dust, dirt and wind are found to be a factor in some individuals with pterygium.

• 9

  Check your family history to learn if you have the potential for developing a pterygium. Some studies indicate the chances for pterygium growth are increased if others in the family have the condition.

Consider Treatment Options

• 10

  Understand that most pterygium do not require any treatment except for cosmetic purposes.

• 11

  Accept the fact that surgery is an option if the growth interferes with vision or the choice is made for cosmetic reasons. Keep in mind that even with surgical removal, the pterygium may return.

• 12

  See your eyecare professional no less than once a year if you feel you have enough criteria to diagnose a pterygium. If you have surgery to remove the growth, follow-up visits will likely be every six months.
