Zusammenfassung
Die optische Kohärenztomografie (OCT) ist ein nicht invasives bildgebendes Verfahren,
das es ermöglicht, transpupilläre Schnittbilder der Retina und der Papilla nervi optici
zu erfassen. Bei Integration eines Scanning-Laser-Ophthalmoskops ist die exakte Lokalisation
und Reproduzierbarkeit der Messungen gegeben. Diese Geräteeigenschaften ermöglichen
auch bei eingeschränktem Fixationsvermögen und bei Kindern die Erhebung zusätzlicher
morphologischer Befunde im Rahmen der Diagnostik neuroophthalmologischer Erkrankungen.
Damit ist es möglich, bei unklaren Sehstörungen makuläre Erkrankungen von Erkrankungen
des Sehnervs abzugrenzen. Verschiedene Formen der Optikusneuropathien lassen sich
voneinander unterscheiden und können sowohl im Schweregrad als auch im Verlauf quantitativ
erfasst werden. Die quantitative Verlaufskontrolle bei Papillenödem, Stauungspapillen
oder auch bei tumorbedingten Optikusatrophien gibt wichtige objektive Hinweise für
die Planung therapeutischer Maßnahmen.
Abstract
Optical coherence tomography (OCT) is a non-invasive imaging technique which provides
the possibility to record transpupillarily cross-sectional scans of the retina and
the optic disc. The exact localisation and reproducibility of the scans are ensured
by the combination with a scanning laser ophthalmoscope. The outcome of this is the
possibility to collect additional morphological data for the diagnosis of neuroophthalmological
diseases particularly in children. OCT data allow for the differentiation of macular
diseases from optic nerve pathology in unexplained visual loss. Various forms of optic
neuropathies can be distinguished and quantitatively characterised with regard to
their severity and clinical course. Serial assessment of papilloedema or optic atrophy
over time gives valuable objective information about the prognosis of the underlying
disease and the therapy planning.
