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
DDx
Treatment
- Artificial tears 5-6x per day
- Cold compresses
- Consider topical abx if unable to differentiate from bacterial conjunctivitis
- Frequent hand-washing (highly contagious)
Disposition
- Follow-up with ophtho if worsening or no improvement in 7 days

- Caused by certain types of adenovirus
Clinical Features
- Usual symptoms of viral conjunctivitis plus:
- Foreign body sensation
- Multiple corneal infiltrates
- Decreased visual acuity
Treatment
- Referral to ophthalmologist to confirm dx and decide if pt requires course of steroids
