H18.833 Recurrent erosion of cornea, bilateral

Name of the Condition

• Recurrent Erosion of Cornea, Bilateral

Summary

Recurrent erosion of the cornea, bilateral, is a condition characterized by repeated breakdown of the corneal epithelium in both eyes, leading to episodes of pain, discomfort, and potential vision disturbances. It often stems from inadequate adherence of the epithelial layer to the underlying basement membrane.

Causes

The condition may result from prior corneal trauma, such as scratches or abrasions, or be associated with underlying disorders like epithelial basement membrane dystrophy. In some cases, it occurs without a clear precipitating event.

Risk Factors

• Previous corneal injuries or abrasions.
• Presence of corneal dystrophies, particularly epithelial basement membrane dystrophy.
• Dry eye syndrome or unstable tear film.
• Genetic predisposition in some cases.

Symptoms

• Sudden eye pain, often upon waking, affecting both eyes.
• Blurred or fluctuating vision in both eyes.
• Excessive tearing and light sensitivity in both eyes.
• Foreign body sensation or grittiness in both eyes.
• Redness of both eyes.

Diagnosis

Diagnosis is typically made through a clinical examination by an ophthalmologist using a slit lamp to assess corneal integrity in both eyes. Fluorescein dye may be applied to highlight epithelial defects. Patient history of recurrent symptoms, especially upon awakening, is also considered.

Treatment Options

• Lubricating eye drops or ointments to promote healing and reduce friction.
• Bandage contact lenses to protect the cornea during healing.
• Corneal debridement to remove loose epithelial tissue.
• Phototherapeutic keratectomy (PTK) to smooth the corneal surface in severe cases.
• Oral analgesics for pain management during acute episodes.

Prognosis and Follow-Up

Most cases improve with appropriate treatment, though recurrence is possible. Regular follow-up with an ophthalmologist is recommended to monitor healing and adjust management as needed. Long-term prognosis is generally favorable with consistent care.

Complications

• Corneal scarring, which may affect vision.
• Secondary infection of the cornea.
• Chronic discomfort or pain.
• Persistent vision disturbances if left untreated.

Lifestyle & Prevention

• Avoid eye rubbing to prevent epithelial damage.
• Use protective eyewear during activities with a risk of eye injury.
• Maintain adequate tear film with lubricating drops if dry eye is present.
• Follow post-procedure care instructions to support healing after treatment.

When to Seek Professional Help

Seek immediate medical attention if symptoms worsen, vision deteriorates significantly, or signs of infection (e.g., increased redness, discharge) develop. Prompt evaluation is important to prevent complications.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record. Ensure the diagnosis is supported by clinical findings, such as slit lamp examination or patient history of recurrent symptoms. Code H18.833 is specific to bilateral involvement and should not be used for unilateral cases.
