Abstract

Gonioscopy-assisted transluminal trabeculotomy (GATT) is a surgery that opens the trabecular meshwork (TM) circumferentially after cannulation of the Schlemm canal (SC) with a flexible illuminated microcatheter or suture. The main purpose of this case report was to describe a new complication of GATT. Herein, we report a case of partial SC, TM, and Descemet membrane (DM) separation during GATT. The patient was a 60-year-old man with a history of glaucoma who underwent GATT. SC, TM, and DM separation occurred intraoperatively during 360 degrees trabeculotomy. The separated tissue fragment was removed from the anterior chamber and later confirmed to be a part of the SC, TM, and DM by histopathologic examination. In our patient, this complication did not cause surgical failure. Various complications associated with GATT have been reported previously. Partial SC, TM, and DM separation may occur during this surgery.
