Hemorrhagic Descemet's Membrane Detachment in Nonpenetrating Glaucoma Surgery.

Purpose: To describe 5 representative cases of hemorrhagic Descemet's membrane (DM) detachment in glaucoma surgery that had different origins, mechanisms and treatments.

Methods: Clinical records of patients that had undergone a nonpenetrating glaucoma surgery, with a diagnosis of hemorrhagic DM detachment were reviewed for demographic data, clinical findings and treatment applied.

Results: Five patients with hemorrhagic DM detachment were included in this case series. They all had different causes, namely a massive hemorrhage at the end of a canaloplasty procedure, a needling maneuver, autologous blood injection, Swan syndrome, and frequent eye rubbing. Hematoma evacuation was performed in 4 eyes, 1 of them from under the scleral flap of the deep sclerectomy and 3 of them through a surgical or laser perforation in DM. Air tamponade was done in most of these cases. One of these cases required transcorneal suture fixation. One case was observed expectantly. All cases successfully recovered but peripheral corneal stain was persistent in 2 cases.

Conclusion: Hemorrhagic DM detachment is a rare but potential vision-threatening complication in glaucoma surgery. Different mechanisms may cause the bleeding and there are several techniques available to approach this complication. Pre-Descemet hematoma should be drained to avoid permanent corneal stain and air/gas tamponade may help to prevent recurrences.
