Zusammenfassung

Der Hauptnachteil moderner Zyklokoagulationen mittels Laser liegt in der im Einzelfall schlecht vorhersagbaren therapeutischen Wirkung. Unerwünschte Schäden und Komplikationen sind aber speziell mit der kontrollierten Zyklophotokoagulation (COCO) v. a. durch die hohe Selektivität der Photoabsorption extrem unwahrscheinlich. Daher können und müssen diese Eingriffe wiederholt werden, wenn die erwünschte Drucksenkung bei der ersten Behandlung nicht eintritt oder später wieder nachlässt. Indikationen und Protokolle für die Wiederholungseingriffe unterscheiden sich dabei nicht von denen der Ersteingriffe.

Abstract

The major disadvantage of modern laser cyclocoagulation is the low predictability of therapeutic success in individual cases. Unwanted damage and complications of controlled cyclophotocoagulation (COCO) are very unlikely, particularly because of the high selectivity of photoabsorption. Therefore, these interventions can and must be repeated if the intraocular pressure reduction is insufficient after the initial treatment or if the pressure increases again later. The indications and protocol for repeat interventions are the same as for the initial intervention.
