Typical Viral Conjunctivitis
Background
- Most common cause of infectious conjunctivitis
- Often preceded by URI (usually adenovirus)
Clinical Features
- Complaint of "red eye" with mild-moderate, watery discharge
- Usually painless unless there is some degree of keratitis
- Often one eye will be involved initially with other eye involved within days
- Unilateral or bilateral conjunctival injection with perilimbal sparing
- Chemosis and subconj hemorrhages may be present
Diagnosis
- Slit Lamp
- Follicles on inferior palpebral conjunctival
- Mild, punctate fluorescein staining of cornea (occasional)
- Must differentiate from herpetic dendrite
Clinical diagnosis of conjunctivitis
| Bacterial | Viral | Allergic | |
|---|---|---|---|
| Bilateral | 50% | 25% | Mostly |
| Discharge | Mucopurulent | Clear, Watery | Cobblestoning, none |
| Redness | Yes | Yes | Yes |
