The cornea is the clear part of the eye that covers the iris and pupil. Pterygium usually does not cause problems or require treatment, but it can be removed if it interferes with vision. Causes The exact cause of pterygium is not known. Too long exposure to ultraviolet rays constitutes a hypothesis as to the causes of the appearance of this protuberance. This occurs more often in people who live in hot countries and spend a lot of time outdoors, or who are exposed to the sun or windy environments. People whose eyes are regularly exposed to things like pollen, sand, smoke or wind have a higher chance of developing this condition. Another risk factor is having light skin and eyes. Symptoms Pterygium does not always cause symptoms.

When they exist, they are generally lightweight. Common symptoms photo retouching include redness, blurred vision, and irritation in the eyes. Burning sensations and itching may also be felt. If the pterygium grows enough to cover the cornea, it can interfere with vision. A thick or large pterygium may also feel like there is a foreign body in the eye.

This disease needs to be treated as scarring can cause vision loss.
