Pterygium
A pterygium is a triangular-shaped, slightly raised, often red growth that develops on the surface of the eye, most commonly on the side closest to the nose.
It is a non-cancerous growth of tissue that arises from the conjunctiva (the white part of the eye) and is often associated with long-term exposure to ultraviolet (UV) light.
Many patients seek evaluation because a pterygium:
- Interferes with vision
- Affects the appearnce of the eye
- Causes irritation, redness, or a foreign body sensation.
A pterygium typically begins on the conjunctiva and may slowly grow onto the cornea. When the growth is confined to the conjunctiva and does not extend onto the cornea, it is called a pingueculum.
If left untreated, some pterygia can continue to grow toward the center of the cornea and obstruct vision. Even when the growth affects only the peripheral cornea, it can alter the cornea’s shape and cause Astigmatism, leading to blurred or distorted vision.
Treatment for Pterygium
Surgery is the only definitive way to remove a pterygium. At Dallas Eye and Ear, our fellowship-trained ophthalmologists, Linda L. Burk, M.D., and Jane E. Gilmore, M.D., perform pterygium excision as an outpatient procedure, typically using local or topical anesthesia so patients can return home the same day.
During surgery, the pterygium is carefully removed, and a conjunctival graft may be placed to reduce the risk of recurrence. After the procedure, the eye is usually patched overnight. Healing generally takes a few weeks, during which patients use prescribed eye drops or ointments to promote healing and reduce inflammation.
In the early stages of recovery, the eye may appear red or mildly swollen, but both comfort and appearance typically improve steadily. Our ophthalmologists provide personalized follow-up care to support healing and achieve the best possible outcome.
