Clinical features

Common clinical findings include eye pain, photophobia, decreased visual acuity in the affected eye, foreign body sensation and conjunctival injection.

Fluorescein examination typically reveals a yellow stained abrasion (representative of the de-epithelialized surface) which is usually visible to the naked eye.


Treatment with a topical antibiotic is recommended for these patients in order to prevent bacterial superinfection.
