Histopathologische Veränderungen bei kornealen Ektasien

Zusammenfassung

Den kornealen Ektasien werden der Keratokonus, der Keratoglobus, die pelluzide marginale Degeneration sowie iatrogene Keratektasien zugeordnet. Bei allen Formen der kornealen Ektasie kommt es zu einer Verdünnung der Hornhaut, die mit einer kornealen Aufsteilung sowie einem irregulären Astigmatismus einhergeht. Nachfolgend wird ein Überblick über histopathologische Veränderungen der verschiedenen kornealen Ektasien gegeben. Ebenso werden histologische Veränderungen nach operativen Verfahren, die im Zusammenhang mit Ektasien durchgeführt werden, wie das korneale Crosslinking und die perforierende Keratoplastik (pKPL) sowie nach refraktiven chirurgischen Verfahren, die potenziell zu einer Ektasie führen können, dargestellt. Neben einer Literaturrecherche erfolgte auch die Aufarbeitung und Untersuchung von histopathologischem Archivmaterial zur exemplarischen Darstellung der spezifischen histologischen Veränderungen.
