The corneal abrasion - 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 of a corneal abrasion includes covering the eye with a patch and analgesics to relieve pain. If the ciliary muscles go into spasm, eyedrops containing cycloplegic drugs may be used to paralyse the ciliary muscle. Antibiotic eyedrops are usually given to prevent bacterial infection (which can lead to a corneal ulcer).
