About Pterygia

Pterygia can range from relatively flat, transparent tissue with a few blood vessels in early stages to thick, opaque tissue that completely obstructs the line of vision. They often originate in the conjunctiva (a tissue that lines the inner corner of the eye) and can extend toward the cornea. They are typically benign (non-cancerous) growths, which do not spread beyond the surface of the eye.

Symptoms of Pterygia

In the early stages, a pterygium rarely exhibits any signs or symptoms. When it does, the symptoms are usually mild.

Early symptoms of pterygia include:

  • Itching
  • Burning sensation
  • Tearing
  • Foreign body sensation
  • Eye redness

Late symptoms of pterygia include:

  • Impairment of vision

Risk Factors for Pterygia

The exact cause of pterygia remains unknown. Pterygia are thought to be associated with too much exposure to ultraviolet (UV) light.

Other risk factors for pterygia include exposure to:

  • Pollen
  • Sand
  • Smoke
  • Wind

Treating Pterygia at UT Health Austin

The early stages of pterygia may cause discomfort and irritation, which is often treated with lubricating or steroid eye drops. If you are experiencing severe discomfort despite using the eye drops or the pterygium grows large enough to cover part of your cornea and begins to affect your vision, your ophthalmologist may recommend surgery to remove it.
