A 68-year-old male presented with redness in the right eye 1 week after surgery for open-angle glaucoma. Slit-lamp examination showed an intraocular pressure of 18 mmHg, few blood clots in the nasal angle, and inward curling of the trabecular meshwork (TM) toward the iris plane in parts of the superior angle with no angle recession in any quadrant [Figure 1]. Cut trabecular leaflet on anterior segment optical coherence tomography [Figure 1], with increased tissue thickness in the trabecular region suggested previous gonioscopic-assisted transluminal trabeculotomy (GATT).[1],[2]

  Discussion Top

With the increasing scope of GATT in glaucoma, curled trabecular meshwork needs to be differentiated from TM tear after trauma, which may also have pigmentation, pigment clumps, and angle recession, apart from a ripped/torn TM on gonioscopy. This possibly happens because of the forcefully ripped remnant of the trabecular shelf during GATT collapsing onto the iris, which has not been reported before.
