H11.813 Pseudopterygium of conjunctiva, bilateral

Name of the Condition

• Pseudopterygium of conjunctiva, bilateral

Summary

Pseudopterygium of conjunctiva, bilateral, is a condition where abnormal fibrous tissue grows from the conjunctiva onto the cornea, resembling a pterygium but lacking the characteristic attachment to the limbus. This growth can cause irritation, visual disturbances, or cosmetic concerns, depending on its size and location.

Causes

The exact cause of pseudopterygium is not fully understood, but it is often associated with chronic inflammation, mechanical irritation, or previous eye trauma. It may also develop secondary to conditions like dry eye syndrome or exposure to environmental irritants.

Risk Factors

• Chronic eye irritation or inflammation
• History of eye trauma or surgery
• Prolonged exposure to dust, wind, or UV light
• Underlying ocular surface diseases (e.g., dry eye)
• Advanced age, as degenerative changes increase

Symptoms

• Eye irritation, redness, or discomfort
• Visible tissue growth on the conjunctiva or cornea
• Sensation of grittiness or foreign body
• Mild visual blurring if the growth encroaches on the pupil
• Excessive tearing or dryness

Diagnosis

Diagnosis involves a comprehensive eye examination, including slit-lamp evaluation to assess the tissue growth’s size, location, and impact on vision. Patient history and symptom discussion help differentiate pseudopterygium from other ocular conditions.

Treatment Options

Treatment depends on symptoms and severity. Mild cases may be managed with lubricating eye drops or anti-inflammatory medications. Surgical removal may be considered for larger growths causing significant irritation or vision impairment.

Prognosis and Follow-Up

Prognosis is generally good with appropriate treatment. Regular follow-up is recommended to monitor for recurrence or progression, especially if environmental irritants are not addressed.

Complications

Potential complications include persistent irritation, vision changes, or recurrence after surgical removal. In rare cases, untreated growths may lead to corneal scarring.

Lifestyle & Prevention

• Protect eyes from UV light with sunglasses
• Use protective eyewear in dusty or windy environments
• Manage underlying conditions like dry eye syndrome
• Avoid rubbing or irritating the eyes

When to Seek Professional Help

Seek care if symptoms worsen, vision changes, or if the growth becomes painful or rapidly enlarges. Prompt evaluation is important for managing complications.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record. Ensure the diagnosis aligns with clinical findings and specify any associated symptoms or complications to support accurate coding.
