Intracorneal Hematoma After Canaloplasty in Glaucoma

Abstract

Intracorneal hematoma is a rare complication of canaloplasty for glaucoma. The blood can be removed without interrupting the Descemet membrane by partial-thickness paracentesis.

Descemet Membrane Detachment After Canaloplasty

“…In 3 of these cases, we chose to drain at the slit lamp because of the presence of significant quantity of blood mixed with Healon GV and the size of the detachment (> 3 mm). 7 The DMD resolved completely in 2 of the 3 eyes. One case progressed to corneal decompensation despite air bubble injection into the anterior chamber and drainage of blood.…”

Hemorrhagic Descemet Detachment After Combined Canaloplasty and Cataract Surgery

“…[2][3][4][5] It is hypothesized that the hemorrhage results from episcleral blood reflux after the collapse of Schlemm canal. As there are more collector channels connecting the episcleral veins to the inferior and nasal canal, 6 this may explain why most reported HDDs have occurred inferiorly, 2,3 and in our case, inferonasally.…”

“…An air or sulfur hexafluoride (SF 6 ) bubble can then be injected to reattach Descemet membrane. 2,3,10 This procedure requires a return to the operating room, further intraocular manipulation and its inherent risk of infection.…”

Trabeculectomy versus canaloplasty (TVC study) in the treatment of patients with open‐angle glaucoma: a prospective randomized clinical trial

“…An intracorneal haematoma is rare and can be removed by stab incision (Tetz et al 2013), partial-thickness paracentesis (Gismondi & Brusini 2011) or Nd: YAG laser Descemet membranotomy (Robert & Harasymowycz 2013). Perforation of the trabeculo-Descemet window during dissection is an intraoperative complication during canaloplasty, which occurs in <10% of all cases (Shingleton et al 2008;Lewis et al 2009;Grieshaber et al 2010;Ayyala et al 2011;Bull et al 2011;Arthur et al 2013;Tetz et al 2013).…”
