What is the primary treatment for viral conjunctivitis?

The primary treatment for viral conjunctivitis is supportive care with cool compresses. Viral conjunctivitis, often caused by adenoviruses, typically resolves on its own within 1 to 3 weeks. Therefore, the cornerstone of management is to relieve symptoms rather than to use specific medications that target the virus.

Cool compresses can help soothe the eyes and alleviate symptoms such as redness and irritation. Patients are also advised to maintain good hygiene, such as frequent handwashing and avoiding touching the eyes, to prevent the spread of the virus.

Topical antibiotics do not target viral infections and are ineffective against viral conjunctivitis, which is why they are not the correct treatment choice. Oral antihistamines may help if there is concurrent allergic conjunctivitis or prior allergic symptoms but do not address viral conjunctivitis specifically. Orbital corticosteroids are not indicated and could potentially worsen a viral infection. Thus, supportive care is the most appropriate approach for managing viral conjunctivitis.
