Zusammenfassung

Die transsklerale Zyklophotokoagulation (ZPK) ist in der Glaukomchirurgie selten Therapie der ersten Wahl. Sie hat hinter den filtrationsverbessernden Verfahren dennoch einen wichtigen Platz, da sie schnell und unkompliziert durchzuführen ist und über einen alternativen Wirkmechanismus ansetzt. Für die „gezielte“ Behandlung des verdeckt liegenden Ziliarkörpers setzt man anatomische Normwerte der Ziliarkörperposition voraus. Diese können jedoch erheblichen Abweichungen unterliegen. Die Diaphanoskopie bietet die Möglichkeit, das Ziliarkörperband vor oder während der Laserbehandlung auf einfache Weise zu lokalisieren und damit die Effizienz der ZPK zu erhöhen. Zudem hilft sie, zu nah an der Irisbasis liegende, nebenwirkungsträchtige Lasereffekte zu vermeiden. Die vorliegende Arbeit geht auf theoretische und praktische Aspekte der Diaphanoskopie des Ziliarkörpers ein.

Abstract

Transscleral cyclophotocoagulation is not usually considered as the first line surgical therapy for glaucoma. However, it still remains an important tool for lowering intraocular pressure in certain patients. It is quick and easy to perform and acts through an alternative physiological approach compared to filtration surgery. As the ciliary body is not directly visible, an empirical distance from the limbus is often used for placement of the laser probe; however, the anatomical structures can be highly variable. Diaphanoscopy provides a very simple and effective way to visualize the ciliary body before or parallel to the cyclophotocoagulation. It helps to direct the laser beam more precisely to the ciliary body and to prevent a false anterior placement of the beams, that carries a great risk of side effects. This article provides an overview on the concept of diaphanoscopy for cyclophotocoagulation.
