What percent of conjunctivitis is viral?
Viral Conjunctivitis Viruses cause up to 80% of all cases of acute conjunctivitis. The rate of clinical accuracy in diagnosing viral conjunctivitis is less than 50% compared with laboratory confirmation. Many cases are misdiagnosed as bacterial conjunctivitis.
What are the types of conjunctivitis?
There are three main types of conjunctivitis: allergic, infectious and chemical.
How is bacterial conjunctivitis treated?
Your doctor may prescribe an antibiotic, usually given topically as eye drops or ointment, for bacterial conjunctivitis.

Having contact with infectious tears, eye discharge, fecal matter, or respiratory discharges can contaminate hands.
What is the best treatment for bacterial conjunctivitis?

Is there a gold standard for bacterial conjunctivitis?
The gold standard for differentiation is bacterial and/or viral cultures, although these are not 100% sensitive and there are reports of viral conjunctivitis with bacterial superinfection. The RPS Adenodetector can also be used to identify some strains of adenvirus responsible for infection.
What do you need to know about allergic conjunctivitis?
Treatment requires good eyelid hygiene and the application of topical antibiotics as determined by culture. Allergic conjunctivitis is distinguished by severe itching and allergen exposure.
