Pterygium (carnocidad en Espanol) comes from the Greek word for "wing." It essentially is an abnormal growth of the conjunctiva, the clear tissue that overlaps the white of your eye. When it grows over the cornea, or the clear covering of the colored part of your eye, this can distort your vision and induce astigmatism. Its irregular surface can also cause tearing or discomfort. They can also cause a gritty feeling in the eye. Sometimes, they can become inflamed and require treatment.
Pterygium are believed to be caused by UV exposure from the sun, or excessive wind or dust.
