title: [Formation of a descemetic bleb after deep sclerectomy and visco-canalostomy: apropos of 2 cases].
abstract: BACKGROUND
  Deep sclerectomy with visco-canalostomy is a new non perforating method for the surgical treatment of glaucoma.
  
  
  METHODS
  We report 2 patients who developed a descemetic bleb after this surgical procedure.
  
  
  RESULTS
  The cornea remained clear for more than ten months, as long as the bleb was not ruptured. In case of rupture, one should inject air into the anterior chamber to fix the descemetic membrane, otherwise the cornea will become quickly cloudy.
  
  
  CONCLUSIONS
  Descemetic bleb formation after visco-canalostomy is a new complication which has to be recognized and treated in order to avoid corneal edema.
