Pterygium & Pinguecula
What is it? Pterygium and pinguecula are related, benign growths on the conjunctiva—the clear tissue covering the white of the eye—caused primarily by chronic exposure to ultraviolet (UV) light, wind, dust, and dry environments. A pinguecula is a yellowish, slightly raised bump that appears on the conjunctiva near the cornea, usually on the side closest to the nose. It consists of degenerated collagen and elastic tissue. A pterygium (pronounced "ter-IG-ee-um") is a wedge-shaped, fibrovascular growth that extends from the conjunctiva onto the clear cornea itself. While both are non-cancerous, a pterygium can induce astigmatism by pulling on the cornea or, if it grows large enough, physically obstruct the visual axis. These conditions are sometimes called "surfer's eye" due to their prevalence in people with high outdoor exposure.
Common Symptoms
- Visible yellowish bump (pinguecula) or fleshy growth (pterygium) on the white of the eye
- Redness, irritation, or a foreign body sensation
- Dryness or burning, especially in windy or dry conditions
- Blurred or distorted vision if the growth encroaches on the cornea
- Cosmetic concern about appearance
- Difficulty wearing contact lenses due to surface irregularity
Risk Factors
- Prolonged exposure to UV sunlight without protection
- Living in sunny, dry, or dusty climates (near equator, high altitude)
- Outdoor occupations or hobbies: farming, fishing, construction, surfing
- Age: most common in adults 20–50
- Male gender (possibly due to occupational exposure)
- Chronic eye irritation from wind or dust
Treatment Options
- Observation & Conservative Care: For asymptomatic or mild cases—artificial tears, lubricating ointments, and UV-protective sunglasses to prevent progression.
- Medications: Short-term steroid drops to reduce inflammation during flare-ups.
- Surgical Removal: Recommended if the growth causes vision changes, significant astigmatism, persistent irritation, or cosmetic concern. Modern techniques include conjunctival autografting (transplanting healthy tissue to the excision site) to reduce recurrence risk to <10%.
- Post-Op Care: Antibiotic/steroid drops and strict UV protection to promote healing and prevent regrowth.
Prevention & Lifestyle Tips
- Wear 100% UV-blocking sunglasses with wraparound style to shield from side exposure.
- Use a wide-brimmed hat outdoors for added protection.
- Apply lubricating drops before outdoor activities in dry/windy conditions.
- Avoid rubbing eyes, which can irritate existing growths.
- Consider moisture-chamber glasses if you work in dusty environments.
When to See a Doctor Consult an ophthalmologist if you notice a new growth on your eye, experience vision changes, or have persistent irritation that doesn't improve with lubricants.
Doctor's Note: While pinguecula rarely requires treatment, pterygium can affect vision and comfort. Surgery is highly effective when performed by an experienced surgeon, but recurrence is possible without proper technique and post-op UV protection. Prevention through sun safety is always better than cure.
