- The most common cause of "pink eye".
- Self limiting disease.
- Very acute and highly infectious external eye infection caused by Adenovirus type 8 and 19.
- The spectrum of the disease could be from mild and inapparent, to full blown cases.
- Foreign body sensation, photophobia, conjunctival hyperemic, eyelid stuck together in the morning, eyelid edema and sero-fibrinous discharge
- Ocular symptoms commonly preceded by systemic symptoms of fever, sore throat and sometimes gastrointestinal disturbances
- Acute onset of unilateral, followed by bilateral papillary and follicular reaction
- Bilateral tender and enlarged preauricular lymph node
- Diffuse epithelial punctate keratitis end erosions over the central cornea appear during the first or second week of the disease
- The epithelial lesions gradually coalesce and form coarse spots of subepithelial infiltrates
- These small-rounded subepithelial opacities may persist for weeks, months or even years
- The first affected eye usually will suffer from relatively more prominent and prolonged keratitis than the fellow eye
- Pseudomembrane formation may occur and can be complicated with conjunctival scarring and symblepharon
- The viruses can be readily spreaded by finger to eye contact, therefore hand washing and proper disinfection of instruments after contact with any patient suspected of having EKC are mandatory.
- Symptomatic relief with artificial tears and systemic analgesic maybe required.
- Topical corticosteroids and cycloplegic are useful in patients with marked iritis and central corneal subepithelial infiltrates
