Corneal abrasions: diagnosis and management

Corneal abrasions are characterized by sudden onset of eye pain, photophobia and tearing. The patient usually relates a history of recent eye trauma but may not recall an inciting event. The differential diagnosis includes direct mechanical injury, recurrent erosion syndrome, ultraviolet keratitis and infection. Most abrasions heal within 24 to 48 hours. Therapeutic modalities include cycloplegia and topical antibiotics. Other treatment methods include pressure patching, topical nonsteroidal anti-inflammatory drugs, bandage contact lenses, collagen shields, anterior stromal puncture and epithelial debridement.
