title: Hemorrhagic descemet detachment after combined canaloplasty and cataract surgery.
abstract: OBJECTIVE
  To describe a case of hemorrhagic Descemet membrane detachment following canaloplasty and to discuss its management using neodymium:yttrium-aluminum-garnet (Nd:YAG) laser Descemet membranotomy.
  
  
  METHODS
  Interventional case report.
  
  
  RESULTS
  A 71-year-old woman with chronic open-angle glaucoma developed a hemorrhagic Descemet detachment after combined phacoemulsification, intraocular lens insertion, and canaloplasty. The hematoma did not improve with initial expectant management. Two and a half weeks after surgery, the Nd:YAG laser was applied to create a break in the Descemet membrane in the region of the hematoma. The intracorneal blood quickly dissipated into the anterior chamber. Visual acuity improved to 20/20. The endothelial cell count was 2342 cells per square millimeter 4 years after the surgery. Pachymetry did not show any long-term alterations as a result of the Nd:YAG treatment.
  
  
  CONCLUSIONS
  Hemorrhagic Descemet detachment is an uncommon complication after canaloplasty. Nd:YAG Descemet membranotomy is a successful means of clearing the hematoma and thus can prevent further complications, such as corneal blood staining.
