What is an eye terrigium?

Answer 1

Looking it up under that name will not work because it is spelled incorrectly!
It is spelled "Pterygium"!
It is a raised wedged shaped growth on your conjunctiva and it is typically caused by excessive sun exposure and chronic eye irritation. It commonly grows from the nasal side of the sclera (white part of eye) and encroaches on to your cornea (clear window in front of eye).

Usually no treatment is required unless the growths starts to grow over your pupil and interfere with vision or if it is severely irritating!

Answer 2

pterygium is a fleshy growth that invades the cornea. It is an abnormal process in which the conjunctiva (a membrane that covers the white of the eye) grows into the cornea. Pterygium may be small or grow large enough to interfere with vision, and commonly occurs on the inner corner of the eye.

The exact cause of pterygium is not well understood. Pterygium occurs more often in people who spend a great deal of time outdoors, especially in sunny climates. Long-term exposure to sunlight, especially ultraviolet (UV) rays, and chronic eye irritation from dry, dusty conditions seem to play an important causal role.

Symptoms

Redness
Irritation
Inflammation
Decreased vision
Foreign body sensation

The symptoms described above may not necessarily mean that you have pterygium. However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam.
Treatment
When a pterygium becomes red and irritated, topical eyedrops or ointments may be used to help reduce the inflammation. If the pterygium is large enough to threaten sight, is growing or is unsightly, it can be removed surgically.

Answer 3

"Pterygium"

A usually triangular whitish growth from the white of the eye encroaching horizontally onto the cornea, most commonly from the side nearest the nose, though they can easily be on both sides of the eye.

Although they are growths they are *not* cancerous, *not* malignant.

They are an over-reaction to exposure : wind, sun, salt...
(so quite common in Australian and Califiornian surfers)
but now are not helped by very dry conditions produced by some air-conditioned offices.

*If* they grow sufficiently across the cornea they need surgical removal. This is not a major problem, but there is some tendency for them to recur.
