H11.063 Recurrent pterygium of eye, bilateral

Name of the Condition

• Recurrent pterygium of eye, bilateral

Summary

Recurrent pterygium of the eye, bilateral, is a condition where fleshy, wing-shaped growths of conjunctival tissue regrow over the cornea in both eyes after previous surgical removal. These regrowths can extend from the conjunctiva onto the corneal surface, potentially affecting vision if they progress.

Causes

The exact cause is unknown, but chronic exposure to ultraviolet (UV) light and environmental irritants such as dust, wind, and smoke are believed to contribute. Genetic predisposition and dry eye conditions may also play a role.

Risk Factors

• Prolonged exposure to UV radiation, often seen in those living near the equator or spending extensive time outdoors.
• Occupations or hobbies that involve exposure to dusty or sandy environments.
• Age, with a higher prevalence in adults aged 30-50.
• Family history of pterygium.

Symptoms

• Persistent redness and inflammation in both eyes.
• Visible growths on the conjunctiva extending onto the cornea in both eyes.
• Irritation or discomfort in both eyes.
• Blurred vision if the cornea is involved in either eye.

Diagnosis

Diagnosis is primarily through a clinical examination by an ophthalmologist using a slit lamp. Patient history to assess previous surgical removal in both eyes is also considered.

Treatment Options

• Surgical excision remains the primary treatment for recurrent pterygium in both eyes.
• Use of adjunctive therapies, such as mitomycin C or amniotic membrane grafts, may be considered to reduce recurrence risk.
• Postoperative care includes topical medications to manage inflammation and prevent regrowth.

Prognosis and Follow-Up

Prognosis depends on the extent of regrowth and response to treatment. Regular follow-up with an ophthalmologist is recommended to monitor for recurrence, especially in the first year after surgery. Early detection of regrowth allows for timely intervention.

Complications

• Recurrent growth may lead to corneal scarring or astigmatism.
• Persistent inflammation can cause discomfort or reduced visual acuity.
• In rare cases, extensive regrowth may require additional surgical procedures.

Lifestyle & Prevention

• Wear UV-protective sunglasses and hats when outdoors.
• Use lubricating eye drops to manage dry eye symptoms.
• Avoid exposure to dusty or windy environments when possible.
• Maintain good eye hygiene to reduce irritation.

When to Seek Professional Help

Seek prompt evaluation if you experience increased redness, pain, or vision changes in either eye, as these may indicate regrowth or complications.

Tips for Medical Coders

Document the bilateral nature of the condition and confirm previous surgical removal history. Ensure clinical notes specify recurrence in both eyes to support accurate coding.
