H17.0 Adherent leukoma

Name of the Condition

• Adherent leukoma

Summary

Adherent leukoma is a condition characterized by a white, scar-like opacity on the cornea that adheres to the underlying tissue. This opacity results from corneal inflammation or injury, leading to fibrous tissue formation. The condition may impair vision depending on the size, location, and density of the opacity. It is often a sequelae of prior corneal damage, such as infection, trauma, or surgery.

Causes

Adherent leukoma typically develops following corneal injury, infection, or inflammation. Common precipitating events include corneal ulcers, herpetic keratitis, chemical burns, or surgical procedures like corneal transplantation. The opacity forms as part of the healing process, where fibrous tissue replaces normal corneal tissue, leading to adhesion and clouding.

Risk Factors

• Prior corneal trauma or surgery
• History of corneal infections (e.g., bacterial, viral)
• Chemical or thermal injury to the eye
• Chronic corneal inflammation or dystrophies
• Prolonged use of contact lenses with poor hygiene
• Systemic conditions affecting corneal health (e.g., autoimmune disorders)

Symptoms

• Blurred or reduced vision
• Visible white opacity on the cornea
• Sensitivity to light (photophobia)
• Eye discomfort or pain
• Difficulty with night vision or glare
• Possible redness or irritation

Diagnosis

Diagnosis is made through a comprehensive eye examination, including slit-lamp biomicroscopy to assess the corneal opacity. Visual acuity testing and corneal topography may be performed to evaluate the impact on vision. A detailed patient history, including prior eye injuries or infections, aids in confirming the diagnosis.

Treatment Options

Treatment focuses on improving vision and managing symptoms. Options may include corrective lenses, corneal transplantation (keratoplasty) for severe cases, or phototherapeutic keratectomy (PTK) to remove superficial opacities. Topical medications, such as lubricants or anti-inflammatory drops, may alleviate discomfort.

Prognosis and Follow-Up

Prognosis depends on the extent of corneal damage and treatment effectiveness. Early intervention can improve outcomes, but residual vision impairment may persist. Regular follow-up with an ophthalmologist is recommended to monitor for complications and adjust treatment as needed.

Complications

• Permanent vision loss if the opacity affects the visual axis
• Increased risk of recurrent corneal infections
• Glaucoma due to corneal scarring
• Persistent eye discomfort or pain
• Difficulty with daily activities requiring clear vision

Lifestyle & Prevention

• Protect the eyes from injury using safety goggles
• Maintain good eye hygiene and avoid contaminated cosmetics
• Manage underlying conditions (e.g., diabetes) to reduce corneal risk
• Avoid rubbing the eyes, especially with contact lenses
• Seek prompt treatment for corneal infections or injuries

When to Seek Professional Help

Consult an ophthalmologist if you experience sudden vision changes, persistent eye pain, or visible corneal clouding. Early evaluation is critical to prevent progression and optimize treatment outcomes.

Tips for Medical Coders

Document the presence of a corneal opacity adhering to underlying tissue, including its location and impact on vision. Ensure clinical notes specify the underlying cause (e.g., prior infection, trauma) to support coding. Adherent leukoma is classified under H17.0 in ICD-10-CM, and documentation should align with the condition's clinical presentation.
