A pterygium is a triangular shaped, slightly elevated, and often red lesion, which may occur on the surface of the eye, usually on the nasal side of the cornea. The lesion is a benign connective tissue overgrowth involving the conjunctiva, which is related to ultraviolet light exposure. Most patients present to the ophthalmologist due to concern regarding the appearance of the lesion, or because the lesion is irritating to the eye or it is adversely affecting vision. Typically, the pterygium is first noticed on the conjunctiva (white of the eye), and then is noted to gradually grow onto the cornea of the eye. When the growth is confined to the conjunctiva, it is known as a pingueculum. Left alone, some pterygia will eventually grow to the center of the cornea, thereby obstructing vision. However, even those that involve only the peripheral cornea often induce significant astigmatism (distortion of the corneal contour), and therefore, reduce vision. 

In general, excision of a pterygium is indicated if it causes significant irritation or begins to degrade vision. Excision of a pterygium may entail a conjunctival transplant
 from the same  eye or application during surgery of an antimetabolite solution (e.g., mitomycin C). Antimetabolites and conjunctival transplants have been shown to decrease the recurrence rates of pterygia, which otherwise recur as much as 40% of the time. The risks of pterygium excision surgery are low and, in general, if the pterygium is excised before it encroaches to the center area of the cornea, the prognosis for post-operative vision is excellent.
