H17.03 Adherent leukoma, bilateral

Name of the Condition

• Adherent leukoma, bilateral

Summary

Adherent leukoma, bilateral, is a condition marked by white, scar-like opacities on both corneas that adhere to underlying tissue. These opacities result from corneal inflammation or injury, leading to fibrous tissue formation. Vision impairment may occur depending on the size, location, and density of the opacities. It often follows prior corneal damage, such as infection, trauma, or surgery.

Causes

Adherent leukoma typically develops after corneal injury, infection, or inflammation. Common triggers include corneal ulcers, herpetic keratitis, chemical burns, or surgical procedures like corneal transplantation. The opacity forms during healing, as fibrous tissue replaces normal corneal tissue, causing 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 in both eyes
• Visible white opacities on both corneas
• Sensitivity to light (photophobia)
• Eye discomfort or pain
• Difficulty with night vision or glare
• Possible redness or irritation

Diagnosis

Diagnosis involves a comprehensive eye examination, including slit-lamp biomicroscopy to assess corneal opacities and adhesions. Visual acuity testing and corneal topography may be performed to evaluate vision impairment. A detailed patient history of prior corneal events is essential for confirmation.

Treatment Options

Treatment focuses on improving vision and managing symptoms. Options may include corrective lenses, corneal transplantation, or phototherapeutic keratectomy (PTK) to remove opacities. Anti-inflammatory medications or lubricating eye drops may be used to reduce discomfort. Severe cases may require surgical intervention.

Prognosis and Follow-Up

Prognosis depends on the extent of corneal damage and treatment response. Vision may improve with intervention, but scarring can be permanent. Regular follow-up with an ophthalmologist is recommended to monitor corneal health and adjust treatment as needed.

Complications

Potential complications include permanent vision loss, corneal neovascularization, or increased risk of recurrent infections. Bilateral involvement may exacerbate functional impairment, affecting daily activities.

Lifestyle & Prevention

Protect eyes from injury by wearing appropriate eyewear. Maintain good hygiene with contact lenses and avoid exposure to irritants. Prompt treatment of corneal infections or injuries can reduce the risk of adherent leukoma development.

When to Seek Professional Help

Seek immediate care for sudden vision changes, eye pain, or visible corneal opacities. Regular eye exams are advised for those with a history of corneal trauma or infection to detect early changes.

Tips for Medical Coders

Use H17.03 for bilateral adherent leukoma. Document the bilateral nature and any associated vision impairment or prior corneal events to support coding accuracy. Ensure clinical correlation with examination findings.
