Die Osteo-Odonto-Keratoprothese bietet durch die biologische Haptik eine gute Gewebe-Integration und damit eine bessere \u00dcberlebensrate und geringere\n          Extrusionsrate. Aufgrund der h\u00e4ufig vollst\u00e4ndigen Hornhautintransparenz stellt die Absch\u00e4tzung des Visuspotenzials pr\u00e4operativ eine besondere Herausforderung dar. Auch w\u00e4hrend der\n          Implantation einer Keratoprothese oder bei notwendigen intraokularen Revisionseingriffen besteht aufgrund der kleinen zentralen Prothesenoptik und der geometrischen Bedingungen der\n          Prothesenhaptik ein eingeschr\u00e4nkter Einblick auf die periphere Netzhaut bzw. die Ziliark\u00f6rperregion und kann den Eingriff erschweren.<\/jats:p><jats:p>\n          Methoden An 7 Augen von 6 verschiedenen Patienten (6\u00a0m\u00e4nnlich, 2 weiblich, mittleres Alter 66\u2009\u00b1\u20099 Jahre) wurde die endoskopische Videoassistenz eingesetzt. Dies erfolgte an 3 Augen\n          zur Indikationspr\u00fcfung und Absch\u00e4tzung des Visuspotenzials im Rahmen einer 23-G-Vitrektomie, an 2 Augen w\u00e4hrend der Implantation und an 2 Augen bei erforderlichen Revisionseingriffen\n          ebenfalls im Rahmen einer Vitrektomie. Es wurde ein Endoskop mit semirigider Optik und einem Bildleitsystem mit 3000 Pixeln und 70\u00b0-Blickfeld der Firma PolyDiagnost und 23-G-Trokarsysteme\n          verwendet.<\/jats:p><jats:p>\n          Ergebnisse Die Endoskopie konnte bei allen untersuchten Augen erfolgreich eingesetzt werden. Nur bei 1 von 3 Augen, bei denen sie zur Absch\u00e4tzung des Visuspotenzials durchgef\u00fchrt\n          wurde, erfolgte im Weiteren die Planung der Keratoprothese, w\u00e4hrend das Visuspotenzial befundbedingt bei 2\u00a0Augen als unzureichend bewertet wurde. Die Beurteilung von Makula und Papille war\n          jedoch durch die Bildaufl\u00f6sung auf den Ausschluss grober Pathologien limitiert. Bei der Implantation konnte die korrekte Positionierung der posterioren Haptik hinter der Wirtshornhaut\n          visualisiert werden. Mittels endoskopieassistierter Vitrektomie konnten retroprothetische Membranen erfolgreich entfernt werden.<\/jats:p><jats:p>\n          Schlussfolgerung Die Endoskopieassistenz bietet Vorteile in der Visualisierung sowohl bei der Indikationsstellung, w\u00e4hrend der Implantation als auch beim Management von\n          Komplikationen nach der Implantation einer Keratoprothese. Die Aufl\u00f6sung des Bildsystems erlaubte jedoch nur eine eingeschr\u00e4nkte Beurteilung. Auch wenn technische Weiterentwicklungen\n          w\u00fcnschenswert sind, stellt die Endoskopie im Kontext der Keratoprothesenchirurgie schon heute eine wertvolle Erg\u00e4nzung dar.<\/jats:p>","DOI":"10.1055\/a-1807-2197","type":"journal-article","created":{"date-parts":[[2022,3,24]],"date-time":"2022-03-24T00:05:23Z","timestamp":1648080323000},"page":"1004-1009","source":"Crossref","is-referenced-by-count":1,"title":["Endoskopieeinsatz
