ICD-10: B30.3

Acute epidemic hemorrhagic conjunctivitis (AEHC), classified under ICD-10 code B30.3, is primarily caused by enteroviruses, particularly enterovirus 70 and coxsackievirus A24. This condition is characterized by sudden onset, conjunctival hemorrhage, and significant discomfort, often leading to a high rate of transmission in community settings. Understanding the standard treatment approaches for this viral conjunctivitis is essential for effective management and patient care.

Overview of Acute Epidemic Hemorrhagic Conjunctivitis

AEHC is highly contagious and can spread rapidly, especially in crowded environments such as schools and daycare centers. Symptoms typically include:

• Redness of the eye: Due to conjunctival injection.
• Hemorrhage: Subconjunctival hemorrhage may be present.
• Tearing and discharge: Watery discharge is common.
• Photophobia: Sensitivity to light can occur.
• Foreign body sensation: Patients often report discomfort or irritation in the eye.

Standard Treatment Approaches

1. Symptomatic Relief

Since AEHC is viral in nature, antibiotics are ineffective. Treatment focuses on alleviating symptoms:

• Cold Compresses: Applying cold compresses to the eyes can help reduce swelling and discomfort.
• Artificial Tears: Over-the-counter lubricating eye drops can relieve dryness and irritation.
• Antihistamines: Oral antihistamines may be recommended if there is associated allergic conjunctivitis.

2. Hygiene and Preventive Measures

To prevent the spread of the virus, patients should be advised on strict hygiene practices:

• Hand Hygiene: Frequent hand washing with soap and water is crucial.
• Avoid Touching the Eyes: Patients should refrain from touching or rubbing their eyes.
• Disinfecting Surfaces: Regular cleaning of commonly touched surfaces can help reduce transmission.

3. Patient Education

Educating patients about the nature of the infection is vital:

• Duration of Symptoms: Patients should be informed that symptoms typically resolve within 1-2 weeks.
• Contagious Period: They should be made aware of the contagious nature of the condition and advised to avoid close contact with others until symptoms resolve.

4. Follow-Up Care

In cases where symptoms persist or worsen, follow-up care is essential:

• Ophthalmologic Evaluation: Referral to an eye care specialist may be necessary if there are complications or if the diagnosis is uncertain.
• Monitoring for Complications: Patients should be monitored for potential complications such as keratitis or secondary bacterial infections.

Conclusion

Acute epidemic hemorrhagic conjunctivitis (ICD-10 code B30.3) is primarily managed through symptomatic relief, hygiene education, and preventive measures. While the condition is self-limiting, proper patient education and adherence to hygiene practices are crucial in controlling outbreaks and minimizing transmission. If symptoms persist or complications arise, further evaluation by an eye care professional is warranted.
