title: Spheroidal degeneration of the cornea: a clinicopathologic case report.
abstract: OBJECTIVE
  To describe a case with clinicopathologic findings of spheroidal degeneration of the cornea in a 78-year-old man.
  
  
  METHODS
  Description of the clinical features of 1 bilateral case with histopathologic findings from the penetrating keratoplasty specimen.
  
  
  RESULTS
  Spheroidal degeneration of the cornea with histopathologic confirmation of extensive elastotic degeneration in anterior corneal stroma.
  
  
  CONCLUSIONS
  The spheroidal degeneration in this patient was of visual significance. The history of repeated, extreme ultraviolet exposure during arc welding is believed to be the proximal cause of these corneal changes.
