Abstract Details


To evaluate the probability of a favourable outcome years after surgery in patients undergoing suture-based ab externo canaloplasty to treat elevated intraocular pressure (IOP) refractory to medications in eyes with primary open angle glaucoma (POAG) or pseudoexfoliation glaucoma (PEX).


'San Maurizio' Regional Hospital, Bolzano, Italy. Secondary Referral, Non-Academic, National Health System Hospital.


Retrospective case series. The charts of all patients that underwent canaloplasty for POAG or PEX between 2010 and 2016 were reviewed. Kaplan–Meier survival analysis, which takes varying length of follow-up into consideration, was performed to estimate the probability of a successful outcome 1, 2 ,3 and 4 years after surgery. Complete success was defined as not needing reoperation or drops to control the IOP, and qualified success as not needing reoperation to control the IOP.


Forty-nine eyes were included. Probability of complete success was 64%, 53%, 49% and 35% respectively 1, 2, 3, and 4 years after surgery. Probability of qualified success was 100%, 97%, 97% and 97% respectively 1, 2, 3, and 4 years after surgery. Canaloplasty was completed in 45 (92%) eyes with successful suture placement in 41 (84%) and viscodistension only in 4 (8%). Four (8%) eyes were converted to deep sclerectomy because of failure to cannulate Schlemm’s canal.


Canaloplasty is both safe and effective in lowering IOP in POAG and PEX. A significant amount of patients remains drop-free even years after surgery. Reoperation for glaucoma is rare.
