B30.3 Acute epidemic hemorrhagic conjunctivitis (enteroviral)

Name of the Condition

• Acute epidemic hemorrhagic conjunctivitis (enteroviral)

Summary

Acute epidemic hemorrhagic conjunctivitis (enteroviral) is a highly contagious viral infection causing inflammation of the conjunctiva, characterized by sudden onset of redness, irritation, and often subconjunctival hemorrhage. It is part of a broader group of viral conjunctivitis and is associated with enterovirus transmission.

Causes

This condition is caused by enteroviruses, specifically certain serotypes that are known to cause epidemic outbreaks. Transmission occurs through direct contact with infected eye secretions or respiratory droplets from an infected individual.

Risk Factors

• Close contact with infected individuals during outbreaks.
• Crowded environments such as schools, daycare centers, or communities with poor sanitation.
• Poor hand hygiene practices.
• Use of shared personal items like towels or eye makeup.
• Recent exposure to areas with known enteroviral activity.

Symptoms

• Sudden onset of redness in one or both eyes.
• Watery or clear discharge.
• Intense eye pain or burning sensation.
• Gritty feeling in the eye.
• Swollen eyelids.
• Sensitivity to light.
• Subconjunctival hemorrhage (visible blood in the white part of the eye).
• Mild fever or upper respiratory symptoms in some cases.

Diagnosis

Diagnosis is primarily based on clinical examination and patient history, focusing on the acute onset of symptoms and epidemic context. A healthcare provider may assess for characteristic signs like subconjunctival hemorrhage and rule out bacterial or allergic causes. Laboratory testing, such as viral cultures or PCR, may be used to confirm enteroviral etiology in outbreak settings.

Treatment Options

• Symptomatic relief with lubricating eye drops (artificial tears) to alleviate dryness and discomfort.
• Cold compresses to reduce swelling and irritation.
• Avoidance of contact lenses and eye makeup during the acute phase.
• Good hand hygiene to prevent spread to the other eye or others.
• Antiviral medications are generally not indicated, as the infection is self-limiting.

Prognosis and Follow-Up

Most cases resolve within 1–2 weeks without complications. Follow-up may be recommended if symptoms worsen or persist beyond this period, or if there are signs of secondary infection. Patients should be advised to monitor for changes in vision or severe pain, which may indicate complications.

Complications

• Corneal involvement (keratitis) leading to blurred vision or light sensitivity.
• Prolonged eye irritation or dryness.
• Secondary bacterial infection in rare cases.
• Rarely, systemic spread of the virus in immunocompromised individuals.

Lifestyle & Prevention

• Practice frequent handwashing with soap and water.
• Avoid touching or rubbing the eyes.
• Do not share personal items like towels, pillows, or eye cosmetics.
• Stay home from work or school during the acute phase to prevent spread.
• Disinfect surfaces and objects that may come into contact with eye secretions.

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist beyond 2 weeks, or if there is significant pain, vision changes, or signs of corneal involvement (e.g., severe light sensitivity, blurred vision). Immediate care is also recommended for immunocompromised individuals or those with severe systemic symptoms.

Tips for Medical Coders

When coding for acute epidemic hemorrhagic conjunctivitis (enteroviral), use ICD-10-CM code B30.3. Ensure documentation supports the acute, epidemic nature of the condition and confirms enteroviral etiology, as this may impact coding specificity. Note that this code is distinct from other viral conjunctivitis codes and should be used when hemorrhagic features are present.
