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. Sometimes squamous cell carcinomas, which also occur as a result of sun exposure, can mimic the appearance of a pterygium. Dr. Omphroy uses the latest techniques such as Tisseel tissue adhesive instead of sutures to speed up recovery time and minimize discomfort and recurrence rates. So far there have been no recurrences to date using this new technique. |
