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.
