A pterygium is an overgrowth of the conjunctiva, which is the thin clear membrane on the surface of the eye. It can grow across the cornea (the clear part over the iris) and can affect the vision. In this case surgical treatment in a day surgery might be required.

Pterygium Symptoms

A pterygium is usually painless, following symptoms may occur:

  • irritation and redness of the eye
  • inflammation, including bloodshot whites of the eye
  • itching and burning sensations
  • change in vision if it grows across the cornea

Treatment & Diagnosis for Pterygium

Pterygiums are diagnosed with a special microscope, generally no other tests are required. Treatment depends on the severity of the condition and may include following:

  • Protection against ultraviolet radiation
  • Drops or ointments
  • Day surgery is only performed if the severity of the condition is high enough. Pterygiums may be removed before it grows across the cornea to avoid scarring and permanent vision problems. It may also be removed for cosmetic reasons
