Viral Conjunctivitis
Key Points
Most viral conjunctivitis is a highly contagious infection caused by adenoviruses or enteroviruses. Features that may help differentiate between viral and bacterial conjunctivitis can include purulence of ocular discharge, presence of preauricular lymphadenopathy, and, in epidemic keratoconjunctivitis, chemosis. Diagnosis is usually clinical. Treatment is usually cool compresses and measures to prevent spread.
