What is Central Pterygium of the Eye?

Central pterygium is a benign growth of the conjunctiva, which is the clear tissue that covers the white part of the eye. This growth usually starts on the inner corner of the eye and gradually moves towards the cornea, the clear front surface of the eye. Central pterygium is different from the normal pterygium, which grows from the outer corner of the eye towards the cornea.

Symptoms of Central Pterygium

Central pterygium can cause a variety of symptoms, including:

  1. Redness and irritation of the eye
  2. Blurred vision
  3. A sensation that something is in the eye
  4. Dryness and itching of the eye
  5. Increased sensitivity to light
Causes of Central Pterygium

The exact cause of central pterygium is not known, but it is believed to be related to prolonged exposure to UV radiation from the sun. Other factors that may contribute to the development of central pterygium include dry eye, wind, dust, and genetic predisposition.

Treatment of Central Pterygium

If central pterygium is causing symptoms, your eye doctor may recommend a variety of treatments, including:

  1. Eye drops to reduce inflammation and redness
  2. Artificial tears to relieve dryness and itching
  3. Surgical removal of the pterygium
  4. Prescription eyeglasses or contact lenses to correct vision problems caused by the pterygium

In some cases, central pterygium may grow back after surgery, but the risk of recurrence can be reduced by following your doctor's instructions for postoperative care, including the use of eye drops and protective eyewear.

Prevention of Central Pterygium

To reduce your risk of developing central pterygium, it is important to protect your eyes from UV radiation by wearing sunglasses or a hat with a brim when you are outside. You should also avoid dry and dusty environments and use artificial tears or eye drops if you experience dryness or irritation of the eyes.

If you notice any changes in your vision or eye health, it is important to schedule an appointment with your eye doctor as soon as possible. With prompt diagnosis and treatment, central pterygium can usually be managed effectively and does not typically lead to serious complications.
