Modified canaloplasty with suprachoroidal drainage versus conventional canaloplasty—1-year results

Abstract

The modified surgery technique of canaloplasty with suprachoroidal drainage yields the opportunity to optimize the IOP-lowering effect of canaloplasty as a non-penetrating surgical procedure while still offering a more favourable safety profile than trabeculectomy. The suprachoroidal access facilitates the most complicated step of the canaloplasty surgery: the localization of Schlemm's canal.

The effect of canaloplasty with suprachoroidal drainage combined with cataract surgery – 1‐year results

“…Hence, the outflow of aqueous humour from the unroofed Schlemm's canal does not drain into an intrascleral filtering space but directly under the choroid (Seuthe et al. ; Szurman et al. ).…”

<p>Canaloplasty in the Treatment of Primary Open-Angle Glaucoma: Patient Selection and Perspectives</p>

“…These procedures are continuously being modified in order to simplify the surgical technique since non-penetrating anti-glaucoma operations are technically challenging. [69][70][71] Nowadays, it can be said, that canaloplasty is not a single procedure, but more of a group of procedures. All of these are conducted within Schlemm's canal however, they differ in their methodology and how it is accessed.…”

“…80 Annual follow up on a large group of 417 patients were published in 2016. 70 In this paper, standard canaloplasty was compared to Canaloplasty with suprachoroidal drainage (retrospective analysis of 180 vs 237 operated eyes). Mean IOP reduction was higher following canaloplasty involving suprachoroidal drainage (35.9%), from baseline 20.9± 3.5 mmHg to 13.1 ± 2.5 mmHg than after conventional canaloplasty (31.2%) from baseline 20.8 ± 3.6 mmHg to 14.0 ± 2.6 mmHg).…”

Suprachoroidale Hydrogelplombe – eine neue minimalinvasive Technik zur Behandlung der rhegmatogenen Netzhautablösung

“…Zudem sind viele Ophthalmochirurgen der Meinung, dass eine Manipulation im suprachoroidalen Raum eine große Gefahr von Blutungen bergen würde. Dies konnten wir jedoch in Stu-dien zur Kanaloplastik mit einer suprachoroidalen Drainage widerlegen [12,13].…”
