Kontaktlose In-vivo-Bildgebung der Hornhaut und Vorderkammer des menschlichen Auges – ein qualitativer Vergleich zweier Bildgebungsmodalitäten in der Praxis

Zusammenfassung

Für die kontaktlose klinische Diagnostik der Hornhaut und Vorderkammer des menschlichen Auges existieren neben der Spaltlampe zwei bildgebende Verfahren: die Scheimpflugkamera sowie die optische Kohäranztomografie (OCT). Diese zwei Verfahren werden kurz vorgestellt und in Bezug auf Bildqualität und Sichtbarkeit relevanter Strukturen verglichen. Hierzu stellen wir verschiedene Beispiele aus der klinischen Spezialdiagnostik vor, wie z. B. Keratokonus, Zustand nach Hornhauttransplantation oder Tumoren okulärer Gewebe.

Abstract

For the contactless diagnosis of the human cornea and anterior chamber in clinical routine, two systems have been established besides the slit lamp: the Scheimpflug camera and optical coherence tomography (OCT). A short introduction into these imaging methods is provided along with a comparison with respect to imaging quality and the visibility of relevant ocular structures. We present different examples from special clinical diagnostics such as keratoconus, condition after keratoplasty or tumours in ocular tissue.
