Corneal Changes From Blunt Trauma
Blunt trauma to the cornea can result in abrasions, edema, tears in the Descemet membrane (Fig 14-12), and corneoscleral lacerations, usually located at the limbus. Traumatic posterior annular keratopathy or corneal endothelial rings have also been described; these rings are whitish gray and occur directly posterior to the traumatic impact. The endothelial rings appear within several hours of a contusive injury and usually disappear within a few days.
