Corneal abrasions are superficial scratches on the corneal surface and are usually associated with a traumatic injury to the eye, although they can also occur in people who suffer from extreme dry eye. The precipitating trauma can be as minor as incidental contact with a finger or small grains of sand or dust getting into the eye.
Corneal abrasions typically cause immediate pain, photophobia, foreign body sensation, tearing, blurry vision, and blepharospasm.
