H11.03 Double pterygium of eye

Name of the Condition

• Double pterygium of eye

Summary

Double pterygium of the eye refers to the presence of two benign, fleshy growths of conjunctival tissue that extend onto the cornea. These growths may cause irritation or visual impairment if they progress onto the corneal surface.

Causes

The exact cause is not fully understood, but prolonged exposure to ultraviolet (UV) light, dry eye conditions, and chronic environmental irritation (such as wind or dust) are associated with its development.

Risk Factors

• Increased UV exposure from sunlight or outdoor activities.
• Living in sunny or windy climates.
• Age, with higher incidence in adults.
• Family history of pterygium.
• Exposure to dust, smoke, or other irritants.

Symptoms

• Eye redness or irritation.
• Foreign body sensation.
• Blurred vision if the growth encroaches on the cornea.
• Visible tissue growth on the conjunctiva or cornea.

Diagnosis

Diagnosis is made through a clinical examination by an eye care professional, typically using a slit-lamp microscope to assess the growth’s location, size, and impact on the cornea.

Treatment Options

• Observation: Regular monitoring if symptoms are mild.
• Lubricating Eye Drops: To relieve irritation and redness.
• Surgery: Pterygium removal may be recommended if vision is affected or for cosmetic reasons.

Prognosis and Follow-Up

Prognosis is generally good with appropriate management. Regular follow-up is recommended to monitor for recurrence or progression, especially after surgical removal.

Complications

• Recurrence after surgery.
• Corneal scarring or irregularity.
• Vision impairment if the growth extends significantly onto the cornea.

Lifestyle & Prevention

• Wear UV-protective eyewear outdoors.
• Use lubricating eye drops in dry environments.
• Avoid prolonged exposure to dust, wind, or smoke.

When to Seek Professional Help

Seek care if symptoms worsen, vision changes occur, or the growth becomes painful or inflamed.

Tips for Medical Coders

Document the presence of two distinct pterygium growths and their impact on vision or ocular surface. Ensure clinical notes specify bilateral involvement to support the code H11.03.
