==Background==
*Most common cause of [[acute red eye]]
*One review with limited evidence found that bacterial conjunctivitis was more common than viral conjunctivitis in children.<ref>Johnson D, et al. "Does This Patient With Acute Infectious Conjunctivitis Have a Bacterial Infection" The Rational Clinical Examination Systematic Review. JAMA.2022;327(22):2231-2237. doi:10.1001/jama.2022.7687</ref>

==Evaluation==
[[File:Conjunctivitis.jpg|thumb|Conjunctivitis with limbus sparing]]
*Typically clinical
**However, a literature review attempting to differentiate bacterial vs viral concludes: '''No single symptom or sign differentiated the two conditions with high certainty'''.<ref>Johnson D, et al. "Does This Patient With Acute Infectious Conjunctivitis Have a Bacterial Infection" The Rational Clinical Examination Systematic Review. JAMA.2022;327(22):2231-2237. doi:10.1001/jama.2022.7687</ref>

{{Clinical diagnosis of conjunctivitis}}

==Management==
*Viral infections - most common cause of conjunctivitis, but difficult to differentiate viral from bacterial 
*Some clinicians treat all possible viral presentations as bacterial conjunctivitis
*Treatment considerations:
**Ointments - soothing effect, but interfere with vision
**Drops - no interference with vision

===Bacterial Causes===
Newborn, see [[Neonatal conjunctivitis]]

===Viral Causes===
*Non-herpetic: supportive care
*Herpetic: [[Acyclovir]], ophto referral

===[[Allergic conjunctivitis|Allergic]]===
*Artificial tears and avoidance of allergens
*Consider topical [[antihistamines]] for severe symptoms

====[[Antihistamines]]====
*Ketotifen 1 drop q8-12hr '''OR''' 
*Olopatadine 1-2 drop daily
