What does pterygium look like?

Pterygium looks like a piece of thin flesh or wing of an insect. It can continue growing until it covers the pupil and block our vision. So it is a kind of disease that we must pay attention to and treat with it timely.

What is pterygium and chalazion?

Pterygia and pingueculae are abnormal growths on the surface of the eye. While a pinguecula does not interfere with sight, a pterygium may grow large enough to cause vision problems. Both conditions are most commonly seen in warm, dry climates. They are not cancers. A chalazion appears as a swollen area, (small lump) on the upper or lower eyelid.

What is the plural of pterygium?

A pterygium (tuh-RIJ-ee-uhm) is an elevated, wedged-shaped bump on the eyeball that starts on the white of the eye (sclera) and can invade the cornea. If you have more than one of these eye growths, the plural form of the word is pterygia (tuh-RIJ-ee-ah).
