Eye Web Evaluation

The evaluation of a pterygium begins with a history and physical exam.

Physical findings in someone with a pterygium may include:

  • Thickening of the thin membrane that covers the white part of the eye
    • Usually starts in the corner of the eye nearest to the nose
    • May be white or yellow
  • Eye redness
  • Eye tearing

Tests are not necessary to make the diagnosis of a pterygium.
