What is a Pterygium?
A pterygium is a benign growth of vessels on the conjunctiva, which is the thin covering on the white part of the eye. They can vary in appearance from looking like chronic pink eye on one side of the colored part of the eye, to very large red colored patches that cover the entire eye.
Pterygiums are generally caused by sun exposure, low humidity, or genetics. Although not harmful, these growths can cause issues with vision, irritation and appearance. At times, pterygiums can be confused with other problems, such as infections or tumors, so seeing an eye doctor is always recommended as they can use a slit lamp microscope to determine the best treatment.
