Clinical diagnosis of conjunctivitis^
| Bacterial | Viral | Allergic | |
|---|---|---|---|
| Bilateral | 50% | 25% | Mostly |
| Discharge | Mucopurulent | Clear, Watery | Cobblestoning, none |
| Redness | Yes | Yes | Yes |
| Pruritis | Rarely | Rarely | Yes |
| Increased Likelihood | Presence of mucopurulent discharge; otitis media | Concomitant pharyngitis; an enlarged preauricular node; contact with another person with red eye | NA |
| Additional | Treatment: Antibiotics | Treatment: Hygiene | Seasonal |
^A literature review attempting to differentiate bacterial vs viral concludes: No single symptom or sign differentiated the two conditions with high certainty.[1]
