A Pterygium is a benign growth of the conjunctiva (lining of the white part of the eye) that grows into the cornea, which covers the iris (colored part of the eye). A pterygium usually begins at the nasal side of the eye. It can be different colors, including red, pink, white, yellow, or gray.

Patients with pterygium often first notice the condition because of the appearance of a lesion on their eye or because of dry, itchy irritation. Pterygium is usually first noticed when it is confined only to the conjuctiva. At this stage it is called a pingueculum. Once it extends to the cornea it is termed a pterygium and can eventually lead to impaired vision.

The most common pterygium treatment is eye drops (artificial tears). In more severe cases when vision is impaired, surgery may be recommended.

Causes

Although the causes of pterygium are not entirely known, it is believed to be caused mainly by exposure to UV light. Another suspected risk is living in a dry, dusty, windy environment. People who live near the equator or play water sports such as surfing and fishing are thus more likely to develop pterygium. Prolonged exposure to these conditions causes the conjunctiva to thicken and the eye to become red and irritated. Collagen in the eye begins to deteriorate, and the eye weakens.

Studies show that there may also be a genetic predisposition to pterygium, with a higher prevalence in men than in women.

Signs and Symptoms

Symptoms of pterygium include dryness, redness, irritation, inflammation, and tearing. In more severe cases, the pterygium may grow over the pupil and limit vision.

Prevention

Sunglasses that block UV rays, particularly sunglasses that provide side coverage, are a good means of protection against pterygium. Wearing a hat with a brim to block sunlight is also helpful. In hot, dry climates, artificial tears (eye drops) should be used to help lubricate the eyes.

Treatment

In most mild cases of pterygium, artificial tears can be used to reduce dryness and irritation.

For patients with severe cases whose vision has been affected, different types of surgery are available. Surgery is the only way to definitively remove a pterygium, but it is not a perfect solution; it requires long-term follow-up, and there is a risk that the pterygium will grow back.

• Conjunctival auto-grafting is a safe and effective technique that surgically removes a pterygium. In this procedure, the pterygium is removed along with the tissue covering the sclera (conjunctiva). Tissue is removed from the inside of the patient’s upper eyelid and replaces the bare sclera.
