What is Pterygium?

Pterygium, also known as surfer's eye, is a noncancerous growth that affects the clear, thin tissue (conjunctiva) of the eye [2]. It is characterized by a fleshy triangular growth that can occur on the bulbar conjunctiva of the eye at the 3 and 9 o'clock meridians [4].

Characteristics of Pterygium

A pterygium typically starts as a small, pinkish or flesh-colored patch on the white part of the eye (sclera) and gradually grows onto the cornea, the outer layer of the eye [6]. It can be triangular or wedge-shaped in appearance.

Causes and Risk Factors

Pterygium is often associated with long-term exposure to UV radiation from the sun, wind, and other environmental factors [8]. Other risk factors include age, gender (more common in men), and occupation (e.g., surfers, fishermen).

Symptoms and Effects

While pterygium can cause some discomfort or irritation, it is generally not a serious condition. However, if left untreated, it may lead to complications such as corneal ulcers or vision problems.

Common Signs and Symptoms of Pterygium

Pterygium, also known as surfer's eye or pinguecula, can cause a range of symptoms that may vary in severity. Here are some common signs and symptoms associated with pterygium:

• Eye Irritation: Inflammation and swelling (conjunctivitis) [1]
• Redness or Bloodshot Eye: A raised pink growth on your eye that may keep getting bigger [2]
• Dry, Itchy, or Burning Eyes: Dry eye, watery eye, or a feeling like there's something stuck in your eye [1]
• Vision Changes: Blurred vision, distorted vision, or a sensation of foreign object in the eye [3], [6]
• Eye Discomfort: A burning sensation, itchiness, or discomfort in the eye [4], [7]
• Sensation of Something in the Eye: Irritation, redness, or a sensation of something in the eye [8]

It's essential to note that pterygium can be asymptomatic in its early stages. However, when inflamed, it can cause significant discomfort and vision problems.

Diagnostic Tests for Pterygium

Pterygium diagnosis involves a combination of physical examination and sometimes additional tests to confirm the condition.

• Slit Lamp Examination: A slit lamp is a type of microscope that focuses a narrow line (slit) of bright light on the eye, allowing your eye care provider to examine the cornea and conjunctiva for signs of pterygium. [1][3]
• Physical Examination: Your healthcare provider may diagnose a pterygium based on a physical examination using a slit lamp, which allows them to see the growth on the surface of the eye. [5][8]
• Eye Exam: A comprehensive eye examination is typically conducted to diagnose pterygium, focusing on the front structures of the eye with a microscope. [7]
• Visual Acuity Test: Assessment of visual acuity can aid in determining the visual impact of the pterygium. [4]

In most cases, no special tests are necessary to diagnose pterygium, and an examination under a slit lamp is sufficient.

Treatment Options for Pterygium

Pterygium, also known as surfer's eye or pinguecula, is a growth on the conjunctiva, the thin membrane covering the white part of the eyes and inside of the eyelids. While it can be unsightly, pterygium is generally not serious and may not require treatment. However, if symptoms persist or worsen, various treatments are available.

Medications for Pterygium

Several medications can help alleviate symptoms of pterygium:

• Artificial tears: These lubricating eye drops can relieve dryness and irritation associated with pterygium.
• Steroid eye drops: Short-term use of corticosteroid drops or ointments may be prescribed to reduce inflammation and prevent the growth from progressing.

Other Treatment Options

In some cases, additional treatments may be recommended:

• Surgery: In severe cases, surgical removal of the pterygium may be necessary.
• Laser therapy: Laser treatment can help remove the growth and improve vision.

Natural Products for Pterygium Treatment

Some natural products have been studied as potential treatments for pterygium:

• Curcumin: A compound found in turmeric, curcumin has anti-inflammatory properties that may help reduce symptoms of pterygium.
• Ellagic acid: This antioxidant has been shown to inhibit the growth of pterygium.

Prescription Medications

Your healthcare provider may prescribe medications to take home with you, including:

• Antibiotics: To prevent infection and promote healing
• Steroid eye drops: To prevent the pterygium from progressing

Prevention is Key

While treatment options are available, prevention is still the best approach. Protecting your eyes from UV radiation, dust, and other environmental factors can help reduce the risk of developing pterygium.

Differential Diagnoses of Pterygium

Pterygium, a non-malignant condition, can be challenging to differentiate from other ocular surface squamous neoplasia (OSSN) conditions. Here are some key differential diagnoses:

• Pseudopterygium: A condition that mimics pterygium but is not caused by UV exposure or chronic irritation [1].
• Pinguecula: A benign growth on the conjunctiva, often associated with aging and UV exposure [6].
• Pannus: An inflammatory condition characterized by a vascularized membrane on the cornea [4].
• Episcleritis and sclerokeratitis: Inflammatory conditions affecting the episclera and sclera, respectively.
• Conjunctival and corneal tumors: Such as limbal squamous cell carcinoma (SCC) or other types of conjunctival and corneal neoplasms [5].

Diagnostic Factors

To differentiate pterygium from these conditions, the following diagnostic factors are important:

• Wing-shaped conjunctival overgrowth onto corneal surface: A characteristic feature of pterygium [8].
• History of chronic UV light exposure: Pterygium is often associated with long-term exposure to UV radiation [6].
• Ocular irritation, inflammation, or trauma: These factors can contribute to the development of pterygium or other differential diagnoses.

Diagnostic Tools

High-resolution anterior segment optical coherence tomography (AS-OCT) can be used to differentiate pterygium from OSSN conditions by providing detailed images of the ocular surface [3].
