By the end, they’ll have a clear understanding of how to manage pterygium and maintain optimal eye health.
Pterygium Explained: From Causes to Complications
Defining Pterygium
A pterygium (surfer’s eye) is a noncancerous growth that develops on the conjunctiva, the clear tissue covering the white part of the eye. This triangular or wedge-shaped growth typically starts in the corner of the eye closest to the nose and can extend onto the cornea. Pterygia often have a pinkish or reddish appearance due to the presence of visible blood vessels.
Environmental and Genetic Factors
The exact cause of pterygium (surfer’s eye) remains unknown, but several risk factors have been identified. Long-term exposure to ultraviolet (UV) light from the sun is a significant contributor to the development of this condition. People who spend a lot of time outdoors, such as farmers, fishermen, and those living near the equator, are at a higher risk. Chronic eye irritation from hot, dry weather, wind, and dust can also play a role in the formation of pterygia. While environmental factors are crucial, genetics may also influence an individual’s susceptibility to developing this eye condition.

Potential Complications
In many cases, a pterygium (surfer’s eye) may not cause any symptoms or require treatment. However, as the growth progresses, it can lead to various complications. Inflammation and swelling of the conjunctiva, known as conjunctivitis, may occur, causing redness, itching, and a burning sensation in the eye. A pterygium can also cause dry eye, watery eyes, and the feeling of having a foreign object in the eye. As the growth extends onto the cornea, it may induce astigmatism by altering the shape of the cornea, resulting in blurred or distorted vision. In severe cases, a pterygium can cause significant cosmetic concerns and interfere with proper contact lens fitting.
Diagnosing Pterygium: Tests and Procedures
Clinical Examination
Diagnosing pterygium (surfer’s eye) typically begins with a comprehensive eye examination conducted by an ophthalmologist or optometrist. During this clinical examination, the eye care professional will carefully inspect the surface of the eye using a slit lamp, a specialized microscope that provides a magnified view of the eye’s structures. The slit lamp allows the doctor to assess the size, location, and extent of the pterygium, as well as any associated redness, inflammation, or abnormalities in the surrounding conjunctiva and cornea. The eye care provider may also evaluate the patient’s visual acuity, eye movements, and overall eye health to determine if the pterygium is causing any vision problems or discomfort.
Corneal Topography
In some cases, additional diagnostic tests may be performed to evaluate the impact of the pterygium on the eye’s surface. Corneal topography is a non-invasive imaging technique that creates a detailed map of the cornea’s curvature. This test is particularly useful in assessing whether the pterygium has induced any astigmatism or irregular corneal shape, which can lead to visual distortions or reduced visual acuity. The corneal topography results can help the eye care provider determine the severity of the pterygium and guide treatment decisions.
Differential Diagnosis
While the diagnosis of pterygium is often straightforward based on its characteristic appearance, it is essential to differentiate it from other eye conditions that may present with similar symptoms or signs. Pseudopterygium, which can occur due to chemical or thermal burns, trauma, or marginal corneal disease, should be considered in the differential diagnosis. Additionally, certain types of ocular surface neoplasia, such as carcinoma in situ or squamous cell carcinoma, may mimic the appearance of a pterygium. In rare cases, a biopsy of the growth may be necessary to rule out malignancy and confirm the diagnosis of pterygium.
Non-Invasive Treatment Approaches
Artificial Tears and Ointments
For mild cases of pterygium (surfer’s eye), artificial tears and lubricating ointments can provide relief from symptoms such as dryness, irritation, and the sensation of a foreign body in the eye. These over-the-counter treatments help to moisturize the ocular surface and fill in any defects in the tear film caused by the abnormal growth. Artificial tears, such as Refresh Tears or GenTeal drops, are typically used during the day, while thicker ointments like Refresh P.M. or Hypo Tears are reserved for nighttime use due to their potential to temporarily blur vision.
Anti-inflammatory Medications
When a pterygium (surfer’s eye) becomes inflamed and causes more severe discomfort, short-term use of topical corticosteroid eye drops may be prescribed. These anti-inflammatory medications, such as Pred Forte 1%, can effectively reduce swelling and redness in the affected eye. However, it is crucial to use these drops under the guidance of an eye care professional, as prolonged use of corticosteroids can lead to side effects like increased intraocular pressure or cataract formation.

Lifestyle Modifications
In addition to medical treatments, lifestyle changes can play a significant role in managing pterygium (surfer’s eye) and preventing its progression. One of the most important modifications is protecting the eyes from further UV exposure, which is a primary risk factor for the development and growth of pterygia. Wearing wraparound sunglasses that block 99-100% of both UVA and UVB rays, even on cloudy days, can help shield the eyes from harmful radiation. Patients should also consider wearing a wide-brimmed hat for added protection. In dry or windy environments, using artificial tears regularly can help maintain proper lubrication of the ocular surface and minimize irritation that may exacerbate the condition.
Surgical Interventions for Pterygium
Indications for Surgery
While many cases of pterygium (surfer’s eye) can be managed conservatively, surgical intervention may be necessary in certain situations. Indications for pterygium surgery include obstruction of the visual axis, pterygium-induced irregular astigmatism, chronic eye irritation, and cosmetic concerns. If the growth extends onto the cornea and impairs vision or causes significant discomfort that does not respond to non-invasive treatments, surgical removal may be the best course of action.
Surgical Methods
The most common surgical technique for pterygium removal involves excising the abnormal tissue and replacing it with a conjunctival autograft. During this procedure, the surgeon carefully removes the pterygium from the cornea and sclera, taking care to avoid damaging the underlying structures. A piece of healthy conjunctiva is then harvested from another part of the eye, usually from under the upper eyelid, and transplanted to cover the bare area left by the excised pterygium. This graft can be secured in place using sutures or fibrin glue, with the latter offering faster surgical times and reduced postoperative discomfort.
In some cases, amniotic membrane transplantation may be used instead of a conjunctival autograft. This technique involves placing a piece of processed placental tissue over the surgical site to promote healing and reduce the risk of recurrence. For recurrent or aggressive pterygia, additional measures such as the use of antimetabolites like mitomycin C may be employed to further minimize the chance of regrowth.

Post-operative Management and Follow-up
After pterygium surgery, patients can expect some discomfort, redness, and irritation in the affected eye. These symptoms can be managed with prescribed eye drops, including antibiotics to prevent infection and corticosteroids to control inflammation. Patients should avoid rubbing or putting pressure on the eye and wear a protective shield while sleeping for the first few weeks after surgery.
Follow-up visits are crucial to monitor the healing process and address any complications that may arise. The eye care provider will assess the graft’s stability, check for signs of recurrence, and adjust the medication regimen as needed. Most patients can resume normal activities within a few days to a week after surgery, but complete recovery may take several weeks. Long-term follow-up is essential to ensure the success of the procedure and promptly address any recurrences or complications.
