title: Corneal decompensation following filtering surgery with the Ex-PRESS(®) mini glaucoma shunt device.
abstract: OBJECTIVE
  To report a case of corneal decompensation due to the Ex-PRESS(®) mini glaucoma shunt device (Ex-PRESS).
  
  
  METHODS
  A 75-year-old man had pseudoexfoliation glaucoma in his right eye. He underwent filtration surgery with Ex-PRESS. His intraocular pressure was 7 mmHg after 9 months.
  
  
  RESULTS
  We observed partial decompensation of the corneal endothelium adjacent to the filtering bleb. Specular microscopy revealed a marked decrease in the endothelial cell density at the center of the cornea.
  
  
  CONCLUSIONS
  Anterior segment optical coherence tomography is very useful for evaluating corneal edema and the position of Ex-PRESS. It is important to follow up with an examination of the corneal endothelial cells.
