INTRODUCTION: To assess the efficacy and safety of retrocorneal membrane interception (RMI)-enhanced penetrating canaloplasty in glaucoma secondary to iridocorneal endothelial syndrome (GS-ICE) with open angle or small peripheral anterior synechiae (PAS). METHODS: A series of 13 patients (13 eyes) with GS-ICE and uncontrolled intraocular pressure (IOP) underwent RMI-enhanced penetrating canaloplasty from March 2019 to October 2020. The patients were followed up at one week, 1 month, 3 months, 6 months, and 12 months, postoperatively. The main outcome measure was surgical success, which was defined as an IOP ≤ 18 mmHg or ≤ 21 mmHg, with glaucoma medications (qualified success), or without glaucoma medications (complete success). Secondary outcome measures were IOP, medication usage, and surgical complications. RESULTS: Among the 13 GS-ICE eyes, 12 (92%) achieved qualified success and 10 (77%) achieved complete success at 12 months postoperatively. The mean IOP decreased from 36.41 ± 8.92 mmHg on 3.0 (IQR 0.5) medications before surgery to 17.09 ± 7.71 mmHg (p = 0.0004) on 0.0 (IQR 0.5) medications (p = 0.0004) at 12 months after surgery. Transient hypotony (38%) and hyphema (38%) were the most common complications. CONCLUSIONS: RMI-enhanced penetrating canaloplasty appears effective and safe in treating GS-ICE with open angle or small PAS up to one year of follow up.
