Background
- Form of viral conjunctivitis that causes keratitis in addition to conjunctivitis
- Caused by adenovirus infection that is highly contagious and tends to occur in epidemics
- Vision-threatening
Clinical Features
- Often preceded by prodrome of cough, high fever, malaise, myalgias, nausea/vomiting
- Usual symptoms of viral conjunctivitis plus:
- Foreign body sensation
- Photohobia
- Chemosis
- Papillae of inf palpebral conjunctiva
- Ipsilateral preauricular lymphadenopathy
- Slit lamp exam - diffuse, superficial keratitis but no corneal ulceration
- Subepithelial infiltrates likely secondary to adenoviral antigens deposited in corneal stroma[1]
Differential Diagnosis
Conjunctivitis Types
Diagnosis
- Clinical diagnosis
Management
- Artifical tears
- Cool compresses
- Cycloplegics if photophobia is severe
Disposition
- Discharge with rapid ophtho follow-up.
