Pterygium

Long-term exposure to ultraviolet (UV) rays from the sun is the leading cause of pterygium. UV radiation damages the conjunctiva, leading to the abnormal growth of tissue. Reflected sunlight from surfaces like water, sand, snow, and concrete increases the risk of developing pterygium.

Windy, dry, or dusty conditions also heighten the risk of pterygium. Irritants such as sand, pollen, and other airborne particles can dry out and irritate the eyes, contributing to the growth of pterygium tissue. Air pollution and chemical exposure further exacerbate this risk.

Individuals over 30 are at a higher risk of developing pterygium, with the condition being most common between the ages of 40 and 60. Genetics play a role as well, with individuals whose family members have had pterygium being more likely to develop it themselves.

People with chronic dry eyes are more vulnerable to pterygium. Insufficient moisture in the eyes makes them more susceptible to environmental damage and increases the likelihood of pterygium formation. Dry eyes can result from medical conditions, medications, or hormonal changes.

Living near the equator or at high altitudes increases the likelihood of developing pterygium due to stronger UV radiation. People with outdoor jobs, like farming, fishing, or construction, are particularly prone to the condition.

Extended contact lens wear, particularly in dry or dusty environments, may contribute to the development of pterygium. Poor hygiene and wearing lenses for extended periods can lead to irritation, which encourages pterygium growth.

For small pterygiums that do not cause symptoms or affect vision, a 'wait and see' approach may be recommended. Regular check-ups help track the growth of the pterygium and ensure timely treatment if necessary.

Artificial tears are used to keep the eyes moist and reduce irritation. These preservative-free drops are especially useful in dry or windy environments, helping alleviate symptoms and prevent further irritation.

Prescription eye drops containing mild steroids or NSAIDs can reduce inflammation and redness during flare-ups. These should be used short-term to avoid potential side effects.

Wearing sunglasses with UV protection and using wide-brimmed hats can help prevent the pterygium from growing or worsening. Avoiding dusty or windy conditions is also recommended to reduce irritation.

Surgery may be necessary if the pterygium affects vision, causes persistent discomfort, or grows rapidly. The goal is to remove the abnormal tissue before it reaches the center of the eye.

Pterygium surgery is usually performed on an outpatient basis using local anesthesia. The surgeon removes the growth and covers the site with healthy tissue from another part of the eye. Modern surgical methods aim to prevent recurrence.

Conjunctival autografting, a technique where tissue from your own eye is used to cover the removal site, has significantly reduced recurrence rates. Other methods, such as amniotic membrane grafts, are also used in some cases to prevent pterygium from returning.

No, pterygium does not resolve on its own. It typically grows over time and may require treatment if it affects vision or causes discomfort.

Surgery is performed under local anesthesia, so there is no pain during the procedure. Post-surgery discomfort is usually mild and can be managed with medication and cold compresses.

Pterygium surgery has a high success rate, especially with modern techniques like tissue grafting. Recurrence rates are typically below 10%.

Contact lens wear is possible with smaller pterygiums, but larger growths may cause discomfort or make fitting lenses more challenging. Your doctor will assess your specific situation.

Initial recovery takes 1 to 2 weeks, with full healing occurring in 4 to 6 weeks. Complete visual recovery and tissue maturation may take several months.

Untreated pterygiums can continue to grow, potentially affecting vision. Larger growths can lead to astigmatism and difficulty correcting vision, though some pterygiums may not need treatment.

Yes, pterygium can develop in both eyes, often at different times. Monitoring both eyes is essential if you have pterygium in one eye.

With early treatment, pterygium typically does not cause permanent vision damage. However, untreated or large pterygiums can lead to corneal scarring, potentially causing long-term vision problems.

While surgery is the only permanent solution, non-surgical treatments like eye drops, UV protection, and avoiding irritants can help manage symptoms and slow growth.

Signs of growth include an increase in size, worsened irritation, or blurred vision. Regular check-ups will allow your doctor to track progress.

Yes, revision surgery is possible if pterygium recurs. Surgeons may use more extensive tissue grafts or medications to reduce the chance of recurrence.

The consultation involves a thorough eye exam, discussion of symptoms, and an explanation of the procedure, expected outcomes, and potential risks.

Long-term side effects are rare but can include mild dry eye symptoms, which typically resolve with artificial tears. Serious complications are uncommon.

The cost varies depending on location and insurance coverage. Many insurance plans cover surgery if it is medically necessary. Contact your insurer for details on coverage.

While more common in adults, children with significant sun exposure can also develop pterygium. Surgery is typically delayed unless it severely affects vision or causes discomfort.
