Corneal Abrasion

• 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
