Abstract Details


The canaloplasty is a microsurgical procedure targeting in dilating the Schlemm canal and, consequently, lowering the intraocular pressure. Interesting seems to be the long-term hypotensive effect of this established glaucoma operation.


Clinic of Ophthalmology, St. Johannes Hospital, Dortmund, Germany


In a retrospective clinical study, 603 patients with moderate open-angle glaucoma were treated with a canaloplasty. The follow-up time of the study was 5 years.


Postoperative hyphema was the most common early postoperative complication. The reduction in intraocular pressure was satisfactory after 12 months with an average intraocular pressure of 14.6 (± 4.2) mmHg compared to 19.1 (± 6.5) mmHg preoperatively. A long-term reduction of local antiglaukomatosa postoperatively was also noted. In diabetics and patients with PEX glaucoma the target pressure was not maintained long term after the canaloplasty. Only a limited percentage of eyes should be reoperated due to a decompensated postoperative intraocular pressure.


Canaloplasty provides a long-term postoperative hypotensive effect in PCOWG, but shows little long-term efficacy in diabetic patients and in patients with PEX glaucoma. The postoperative complication rate is low.
