A growth on the eye

Many times, a pterygium does not cause symptoms.  However, an inflamed or enlarged  pterygium may cause redness and inflammation.

A pterygium can grow onto the cornea (the clear, outer layer of the eye). This can distort the shape of the cornea, causing a condition called astigmatism.

Symptoms of pterygium may include:

  • Burning
  • Gritty feeling
  • Itching
  • Sensation of a foreign body in the eye
  • Blurred vision

Causes of Pterygium:  Significant risk factors include:

    • Prolonged exposure to UV light
    • Dry eye

    • Lubricating eyedrops or ointments, such as Blink or Refresh drops
    • Occasional use of vasoconstrictor eyedrops, such as Naphcon A
    • Short course of steroid eyedrops, such as FML or Lotemax
