What Is Terigion

Actually it is called Pterygium(the P is silent) and it is an extra piece of skin that overlaps the cornea and stretches onto the pupil eventually causing decreased vision. Most commonly caused by long exposures to the sun. It can be very irritating and painful. The only way it can be totally removed is by surgery, but to decrease the irritation is by taking a prescribed steroid drop or a soothing artificial tear drop.    Hope this helps.

All the replies on the pterygium are right so I do not need to redefine it. It is ususally a wedged shaped fibrovascular degenerative growth of the conjuctiva. The problem about it is that it stretches(grows and encroaches) over the cornea. Now the cornea is meant to be clear and colourless. so what a pterygium does is to cause some kind of problems with vision either reduced vision, distorted vision or the likes.

Risk factors for developing it are: Prolonged exposure to sun, Sand, particles. So it is commoner in outdoor workers, farmers, welders and the likes.

Because of the high recurrence after surgery it is recommended that combination therapy be used to treat it. That is surgery and radiotherapy or surgery and chemotherapy.

It is better you do surgery and then combine with something. it is a minor procedure I assure you. (though has its own complications). see your Opthalmolgist for more info.

Do something as soon as you can because it would continue to grow if you do not.

I would be glad to answer any further comments.
