A pterygium is a pink or red-colored growth on the surface of the eye. It is usually highly visible against the white of the cornea. It is similar to a pinguecula (see “pinguecula” section) but it extends on to the cornea.

It is typically not dangerous. However, it could grow over time, and eventually cover the pupil of the eye, which is what allows light into the eye. This can severely interfere with vision, and this pterygium to be removed.

Pterygiums are most often associated with individuals who spend a lot of time outdoors. That is why a common cause is thought to be exposure to ultraviolet rays of light for long periods of time.
