Intermediate Outcomes of ab Externo Circumferentialtrabeculotomy and Canaloplastyin POAG Patients with Prior Incisional Glaucoma Surgery

“…Canaloplasty and ECT are two representative Ab externo procedures of SC-based glaucoma surgery. Canaloplasty was reported to be a feasible, e cient, and safe candidate for POAG with prior incisional glaucoma surgery with both intact and disrupted SC [9,10] . Circumferential trabeculotomy, either ab interno or ab externo, was also practiced on POAG patients and presented good IOP control [7,8] .…”

“…It was reported that canaloplasty [5,6] and ECT [7,8] provide good IOP reduction with a favorable safety pro le as an initial procedure for POAG. Moreover, canaloplasty is also a candidate for POAG with prior failed ltering surgeries with or without intact schlemm's canal (SC) [9,10] . Recently, a study reported that circumferential trabeculotomy could be a feasible remedy for POAG with failed canaloplasty [11] .…”

Intermediate outcomes of ab externo circumferential trabeculotomy and canaloplasty in POAG patients with prior incisional glaucoma surgery

“…Inclusion criteria for this study were: The full details of the surgical procedures were reported previously [9,13] . Brie y, fornix-based conjunctival and scleral aps were made next to the prior incision.…”

Minimally Invasive Glaucoma Surgery: What Do We Know? Where Should We Go?

“…Indeed, when we perform canaloplasty on patients with POAG with failed trabeculectomy, the microcatheter could be easily inserted around the entire circumference and the postoperative IOP gradually becomes controlled, compared with subjects receiving circumferential trabeculotomy alone. 71,72 This finding indicates that a more collapsed SC, as a result of damage from trabeculectomy, could have a lumen that remains open. The surgical procedure permits drainage of the aqueous humor into SC.…”
