Descemet Membrane Detachment During Ab-Interno Canaloplasty

Canaloplasty is a minimally invasive glaucoma procedure that aims to restore aqueous outflow through the Schlemm canal. Despite its excellent safety profile, complications can occur, including hyphema, creation of a cyclodialysis cleft, and incorrect passage of the catheter into the suprachoroidal space. Descemet membrane detachment (DMD) is an infrequent complication of canaloplasty and can be associated with significant visual decompensation, particularly when involving the central visual axis. Herein, we describe a case of a patient who underwent canaloplasty through an iTrack microcatheter and whose course was complicated by a hemorrhagic DMD with viscoelastic trapped in the interface between the Descemet membrane and posterior corneal stroma. This case helps to highlight the importance of considering factors such as location, relationship to pupil, size, and contents when determining the management of DMDs.
