H17.00 Adherent leukoma, unspecified eye

Name of the Condition

• Adherent leukoma, unspecified eye

Summary

Adherent leukoma is a condition marked by a white, scar-like opacity on the cornea that adheres to underlying tissue. This opacity arises from corneal inflammation or injury, leading to fibrous tissue formation. Vision impairment may occur depending on the opacity’s size, location, and density. 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
• 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 involves a comprehensive eye examination, including slit-lamp microscopy to assess the cornea’s opacity and adhesion. Visual acuity testing evaluates vision impairment. Additional tests, such as corneal topography or anterior segment imaging, may be used to determine the opacity’s extent and impact on ocular structures.

Treatment Options

Treatment focuses on improving vision and managing symptoms. Options include corneal transplantation (penetrating keratoplasty) for significant vision loss, phototherapeutic keratectomy (PTK) to remove superficial opacities, or contact lenses to enhance visual clarity. Anti-inflammatory medications may be prescribed to reduce associated irritation.

Prognosis and Follow-Up

Prognosis depends on the opacity’s size, location, and treatment response. Early intervention can improve vision, but severe cases may have persistent impairment. Regular follow-up with an ophthalmologist is recommended to monitor for complications, such as infection or graft rejection, and adjust treatment as needed.

Complications

Potential complications include permanent vision loss, corneal neovascularization, or increased risk of recurrent infections. Surgical interventions carry risks like graft failure, astigmatism, or intraocular pressure elevation. Chronic irritation may also lead to discomfort or photophobia.

Lifestyle & Prevention

Preventive measures include protecting the eyes from injury (e.g., wearing safety goggles) and avoiding known irritants. Proper contact lens hygiene and prompt treatment of corneal infections reduce the risk of adherent leukoma. Regular eye exams help detect early changes and guide preventive care.

When to Seek Professional Help

Seek immediate care for sudden vision changes, severe eye pain, or increased redness, as these may indicate complications. Follow up with an ophthalmologist if symptoms persist or worsen despite initial treatment, or if vision declines over time.

Tips for Medical Coders

Document the eye affected (unspecified in this code) and any associated factors, such as prior trauma or infection, to support coding accuracy. Ensure clinical notes specify whether the condition is unilateral or bilateral, as this may impact coding specificity. Verify that the diagnosis aligns with the clinical presentation and documentation.
