Die Filtrationschirurgie zählt zu den ältesten Prinzipien der Glaukomchirurgie. Ergänzend
zur Trabekulektomie wurden neuere Stent-basierte Verfahren wie der Preserflo-Microshunt
und der XEN-Stent entwickelt. Dieser Artikel stellt diese drei filtrierenden Operationstechniken
vor. Er fasst die Operationstechnik, Daten zur Effektivität sowie Art und Häufigkeit
von Komplikationen zusammen und versucht, sie soweit möglich miteinander zu vergleichen.
Abstract
Glaucoma filtration surgery has been a standard surgical therapy for decades. An increasing
knowledge about wound healing processes in the eye, the introduction of antimetabolite
treatment and continuous improvements of the surgical technique helped making trabeculectomy
– the prototype filtration surgery – a very effective therapeutic tool. However, best
results will only be regularly achieved with a high level of experience and time dedicated
to postoperative follow-up. Furthermore, the potential for severe early and late complications
still remains high. Thus, novel stent-based filtration surgery approaches, such as
the Preserflo and the XEN shunt have been introduced. This review presents these three
bleb-forming filtration procedures, covering the basic principles of surgical technique,
data on effectivity as well as complications.
