PURPOSE: To report the incidence and management of haemorrhagic Descemet membrane detachment (HDMD) in canaloplasty and phacocanaloplasty. METHODS: This study included 105 eyes of 92 patients with uncontrolled open angle glaucoma who underwent canaloplasty and phacocanaloplasty between 2010 and 2014. Eyes that developed either HDMD or non-HDMD were identified. The main outcome measures were the development of HDMD and non-HDMD, best corrected visual acuity, recovery time after Descemet membrane detachment (DMD), intra-ocular pressure (IOP) and number of antiglaucoma medications. Each eye was managed according to the time of development, type and extent of DMD. RESULTS: Ten eyes (9.5%) developed DMD- four eyes underwent canaloplasty (3.8%) and six eyes underwent phacocanaloplasty (5.7%). Three of 10 eyes developed non-HDMD while seven of 10 developed HDMD, the majority of HDMD cases occurred in combination with phacocanaloplasty (five of seven). The non-HDMD eyes resolved completely within 2 weeks without intervention. One eye with HDMD was observed for 2 weeks, before a 15% sulphur hexafluoride (SF6) intracameral injection was given. The patient developed a dense corneal stain that was resolving slowly over 30 months. One eye with HDMD underwent YAG laser membranotomy 2 weeks after being identified, which regained corneal transparency 1 month after treatment, while the remaining five eyes underwent immediate surgical drainage and regained corneal transparency 1 day post-procedure. CONCLUSION: HDMD occurred in up to 6.7% in canaloplasty and phacocanaloplasty procedures, mostly during catheter withdrawal and the viscodilation step. Early recognition and management prevented further manipulation.
