Zusammenfassung
Die operative Behandlung des Offenwinkelglaukoms orientiert sich an Werten wie Zieldruck, Erfolgsquote und Komplikationsquote. Eine neue nicht perforierende Methode stellt die Kanaloplastik dar. Ziel dieser Arbeit soll die Darstellung des operativen Verfahrens,der Indikation,der Ergebnisse und der Nachsorge sein. Während der Operation wird eine Viskokanalostomie vorgenommen, wie sie von Robert Stegmann beschrieben worden ist. Danach wird ein Mikrokatheter mit einem Durchmesser von 200 μ verwendet, um den Schlemm-Kanal in der gesamten Zirkumferenz zu dehnen. Hierbei werden Mikrovolumina eines höher viskösen OVD (höher visköses Hyaluronat) injiziert. Nach erfolgter Dilatation wird der Katheter wieder zurückgezogen und gleichzeitig damit ein 10.0-Prolene-Faden im Kanal platziert und straff geknüpft, um permanent Spannung auf das Trabekelmaschenwerk zu bringen.
Abstract
Evaluation of the surgical treatment of open angle glaucoma depends on values, such as target pressure, success rates and complication rates. Canaloplasty is a new non-penetrating method for glaucoma surgery and the aim of this article is to present the surgical approach, indications, results and post-operative therapy. During the operation a viscocanalostomy according to Robert Stegmann is performed. Subsequently a microcatheter with an outer diameter of 200 μ is used to circumferentially dilate Schlemm’s canal. During the dilation microvolumes of a high viscosity ophthalmic viscosurgical device (OVD) (sodium hyaluronate) are injected. After successful dilation the catheter is retracted and at the same time a 10.0 Prolene suture is placed in the canal and closed tightly to apply permanent tension to the trabecular meshwork.
