{{Clinical diagnosis of conjunctivitis}}

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

===[[Antibiotics]] for Bacterial Causes===
*Treatment for bacterial organisms is targeted toward S. aureus, S. pneumoniae, H. influenzae, Pseudomonas, N. gonorrhea, C. trachomatis
*Contact lens wearers should be given coverage for Pseudomonas with one of the fluoroquinolone drops.
**Contact lens wearers should be advised to not wear their contacts until asymptomatic
