Zusammenfassung
Hintergrund: Beschreibung der ultraschallbiomikroskopischen Ergebnisse eines Falles mit beidseitigen
multilobulären primären Iridoziliarzysten, die sich als chronisches Winkelblockglaukom
präsentieren. Anamnese und Befund: Bei einer 82-jährigen Patientin wurde in einem Tertiär-Augenzentrum eine gründliche
Untersuchung des allmählichen Verlusts der Gesichtsfelder sowie der Papillen vorgenommen.
Die klinische Beurteilung der Patientin ergab ein Winkelblockglaukom und einer Katarakt
in beiden Augen. In der ultraschallbiomikroskopischen Untersuchung wurden beidseitig
multilobuläre Iridoziliarzysten festgestellt. Die beidseitig vorliegenden multiplen
Iridoziliarzysten verursachen eine Iriselevation und demzufolgenden Kammerwinkelblock.
Schlussfolgerungen: Primäre Iridoziliarzysten erreichen selten eine Größe, die den Kammerwinkel beeinträchtigt.
Sie gelten in der Regel als gutartige und stationäre Läsionen. Mit der Ultraschallbiomikroskopie
steht den Augenärzten heute ein höchst wertvolles Instrument für die Diagnose und
Überwachung dieser Läsionen zur Verfügung.
Abstract
Purpose: The aim of this study was to describe the findings of ultrasound biomicroscopy (UBM)
in a case with bilateral, multilobulate primary iridociliary cysts presenting as chronic
angle-closure glaucoma. History and Signs: An 82-year-old woman was admitted to a tertiary ophthalmological centre for a thorough
exploration of the gradual deterioration of her visual fields and optic discs. Clinical
evaluation of the patient revealed angle-closure glaucoma and cataract in both eyes.
The use of UBM disclosed the presence of bilateral, multilobulate iridociliary cysts
in all quadrants. The presence of multiple and bilateral iridociliary cysts was the
cause of iris anterior displacement and the subsequent angle closure in this patient.
Conclusions: Primary iridociliary cysts may rarely progress to a size that can compromise the
angle. They are usually considered as benign and stationary lesions. The advent of
UBM is an invaluable tool for the contemporary ophthalmologist in order to set the
diagnosis and follow the evolution of those lesions.
