- May occur following mechanical or chemical injuries.
- Usually results from corneal epithelium removal with intact Bowman's
membrane.
- Clinical features:
- Symptoms: pain, photophobia, foreign body sensation, tearing
and history of ocular trauma
- Signs: fluorescein staining of the epithelial defect
- Re-epithelialization of the corneal surface usually
begins within 24 hours after trauma.
- The healing process depends on the size of the
abrasion, type of injury and limbal function.
- Management:
- Debridement of loose epithelium
- Antibiotic ointment or drops
- Cycloplegic agent is occasionally added if photophobia or traumatic
iritis is present
- Eye patching can be considered, except in contact lens wearers
and trauma involving organic matter
- For contact lens wearer, antibiotics should include anti-pseudomonal
coverage
