What are pterygium and pinguecula?

• Pinguecula
  is an eye disease that changes from normal tissue into a benign tumor on the conjunctiva. It appears as a raised bump or thin yellow film, usually found on the white of the eye closer to the cornea at the front of the eye than at the tail. Pinguecula can grow until it infiltrates the cornea. If it invades the cornea, it is called pterygium.
• Pterygium
  is an eye disease that may occur after pinguecula. It usually appears as a white, yellow or pink, triangular-shaped bump on the conjunctiva that protrudes into the cornea. If the pterygium is large enough to block vision, it often requires surgical removal.

Bad light…destroys the “eyes”

Symptoms of “Pterygium and Pinguecula”

In the early stages of “Pterygium and Pinguecula”, there are usually no symptoms. You will only see abnormal tissue on the conjunctiva. But if there is inflammation or it gets worse. The patient will feel eye pain, irritation, itching, burning eyes, tears, red eyes. Sometimes it may feel like there is dust in the eye. And if you have to face strong wind, dust, smoke, sand regularly. It will make the pterygium and pinguecula more inflamed.

If “Pterygium” becomes severe and spreads close to the center of the cornea. The cornea will be pulled, causing the corneal curvature to change. This may cause the patient to have blurred vision and may develop astigmatism.

Choose a treatment that is appropriate for the level of the disease.

The doctor will consider the treatment method that is appropriate for the severity of the disease.

• If the disease is not severe, the cataract is small, the patient does not have any irritation, and vision is still normal, treatment may not be necessary. The doctor will advise the patient to prevent the disease from getting worse by strictly protecting the eyes from ultraviolet radiation to prevent the cataract from becoming more severe and spreading.
• If there is inflammation, irritation or redness of the eyes, the doctor will recommend eye drops to reduce inflammation.
• For pterygium, where the tissue extends all the way to the center of the cornea and obscures vision, the doctor will recommend surgical removal of the pterygium from the conjunctiva and corneal surface. Currently, doctors often perform surgery and place new tissue (graft), which may be the patient’s conjunctiva or use a specially prepared amniotic sac provided by the Thai Red Cross, to reduce the chance of recurrence.
