A pterygium is a non-cancerous growth of the conjunctiva, the clear, thin tissue covering the white part of the eye. Pterygium can occur in one or both eyes. The growth itself appears wedge-shaped or wing-shaped, giving the disorder its name. Pterygion is the Greek word for “wing”.
Generally, pterygium causes no pain, but you may feel self-conscious about its appearance and wish to have it removed. Mild cases of pterygium can be removed safely under topical anesthetic. In other cases, the pterygium may grow onto the cornea and affect your vision, necessitating surgical removal.
At Patel Eye Associates in Edison, New Jersey, board-certified ophthalmologists Dr. Hitesh K. Patel and Dr. Himanshu S. Shah are highly skilled in evaluating and treating pterygium.
Pterygium Causes and Symptoms
The exact causes of pterygium are not well understood. Doctors do know that prolonged exposure to sunlight, especially ultraviolet light, may contribute to the formation of pterygium.
Individuals who experience chronic eye irritation due to working in windy, sandy, dry or dusty environments are more prone to develop this condition. For these reasons, many doctors caution pterygium patients to wear a hat and sunglasses outdoors and to avoid prolonged exposure to the sun.
Many individuals with pterygium experience no symptoms and require no medical treatment. For some patients, pterygium may become swollen or appear inflamed. For others, the area becomes thickened. It may cause a feeling of having a foreign body lodged in the eye.
Advanced pterygium can distort the corneal surface, leading to astigmatism.
Treatment is determined by the size of the pterygium and your symptoms. Dr. Patel and Dr. Shah will conduct a very thorough eye examination. They may prescribe an eye lubricant or steroid drops to reduce redness and swelling. If necessary, Dr. Patel and Dr. Shah may recommend surgical removal options.
Milder forms of pterygium can be removed in a short time using a topical anesthetic. If Dr. Patel and Dr. Shah are concerned about recurrence of the pterygium, they may suggest a very safe procedure known as autologous conjunctival autografting, or AmnioGraft®. This procedure involves the suturing or gluing of a piece of surface eye tissue in the area where the pterygium was removed. Along with Mitomycin-C, an antimetabolite, your chances of pterygium recurrence are greatly reduced.
