A scratch or defect in the epithelium (outer layer) of the cornea caused by a small, sharp particle in the eye (see eye, foreign body in) or by an injury. Corneal abrasions usually heal quickly but may cause severe pain and photophobia. Treatment includes covering the eye with a patch, analgesic drugs to relieve pain, and, if the eye muscles go into spasm, eyedrops containing cycloplegic drugs (which paralyse the ciliary muscle, preventing accommodation). Antibiotic eyedrops are usually given to prevent bacterial infection, which can lead to a corneal ulcer.
