Purpose: To report a case that developed a large Descemet membrane detachment after viscocanalostomy.
Methods: Case report. A 60-year-old man with primary open-angle glaucoma underwent viscocanalostomy RE. One day after surgery, a small, localized detachment of Descemet membrane was present at the operation site. Six months after surgery, he had a large superior Descemet membrane detachment involving his visual axis.
Results: The Descemet membrane remained attached after descemetopexy with sodium hyaluronate and air. Final visual acuity was 20/80, and intraocular pressure was 17 mm Hg without medication.
Conclusion: Detachment of the Descemet membrane should be recognized as a potential complication of viscocanalostomy.
