B30.0 Keratoconjunctivitis due to adenovirus

Name of the Condition

• Keratoconjunctivitis due to adenovirus

Summary

Keratoconjunctivitis due to adenovirus is an inflammation of the cornea and conjunctiva, the thin membrane covering the white part of the eye and inner eyelid, caused by adenovirus infection. It is highly contagious and often presents with redness, irritation, and visual disturbances.

Causes

Keratoconjunctivirus due to adenovirus is caused by adenoviruses, which are common respiratory viruses. Transmission occurs through direct contact with infected eye secretions or respiratory droplets.

Risk Factors

• Close contact with infected individuals.
• Crowded environments like schools or daycare centers.
• Poor hand hygiene practices.
• Recent upper respiratory infections or colds.
• Use of contact lenses with inadequate hygiene.

Symptoms

• Redness in one or both eyes.
• Watery or clear discharge.
• Itching or burning sensation.
• Gritty feeling in the eye.
• Swollen eyelids.
• Sensitivity to light.
• Blurred vision or visual disturbances.

Diagnosis

Diagnosis is primarily based on clinical examination and patient history. A healthcare provider may assess symptoms and rule out bacterial or allergic causes. In some cases, swabs of eye discharge may be taken for laboratory testing to confirm the viral etiology.

Treatment Options

• Symptomatic relief with lubricating eye drops (artificial tears) to reduce dryness and discomfort.
• Cold compresses to alleviate swelling and irritation.
• Antiviral medications are rarely used unless severe or persistent.
• Avoidance of contact lenses until symptoms resolve.

Prognosis and Follow-Up

Most cases resolve within 1-2 weeks with supportive care. Follow-up may be recommended to monitor for complications, such as corneal scarring or persistent visual changes.

Complications

• Corneal scarring or opacity.
• Persistent visual disturbances.
• Secondary bacterial infection.
• Chronic dry eye.

Lifestyle & Prevention

• Practice good hand hygiene, especially after touching the eyes.
• Avoid sharing personal items like towels or makeup.
• Stay home from work or school to prevent spread.
• Disinfect surfaces and objects that may be contaminated.

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist beyond two weeks, or include severe pain, vision loss, or light sensitivity.

Tips for Medical Coders

Document the presence of keratitis (corneal involvement) and adenovirus as the causative agent. Ensure clinical notes support the diagnosis to justify the specificity of B30.0.
