title: OCT imaging of a traumatic endothelial ring.
abstract: OBJECTIVE
  To report a case of a traumatic corneal endothelial ring sustained from a nonblast injury and its resolution with corneal optical coherence tomography (OCT) imaging.
  
  
  METHODS
  The authors present a report of the clinical case with imaging of the lesion using corneal OCT.
  
  
  RESULTS
  A 59-year-old man presented 1 day after sustaining a nonpenetrating foreign body injury to his cornea. Slit-lamp examination showed an endothelial annular lesion of 3.3 mm in diameter, which was grey-white in color. No other signs of traumatic injury were present. Stromal edema and endothelial disruption were demonstrated on corneal OCT. This resolved completely on review.
  
  
  CONCLUSIONS
  We describe a concussive injury that specifically disrupts endothelial cells in an annulus on the perimeter of the impact zone. This results in transient stromal edema immediately anterior to the injured endothelial cells. These OCT findings corroborate previous animal studies on the mechanism and sequelae of injury.
