Zusammenfassung
Das Pseudoexfoliationssyndrom (PEX-Syndrom) zählt heute zu den am häufigsten diagnostizierten Ursachen des Offenwinkelglaukoms, wobei auch eine Assoziation mit einem erhöhten Risiko für Gefäßerkrankungen (z.B. Hypertonie, Angina pectoris, Myokardinfarkt, apoplektischem Insult, retinale Thrombosen) beschrieben worden ist. Ziel dieser Studie war es zu untersuchen, ob mit Hilfe des pulsatilen okulären Blutflusses (POBF) bei diesem Syndrom eine veränderte okuläre Durchblutungssituation zu verifizieren ist.
Augen mit PEX-Syndrom oder Pseudoexfoliationsglaukom (PEG) wurden einer Gruppe von Augen mit normalen Befunden gegenübergestellt. Es erfolgte bei diesen (insgesamt 29 Augen) eine komplette ophthalmologische Untersuchung inklusive Messung des okulären Blutflusses mittels Ocular blood flow Tonometer nach Langham und eine Nervenfaser-dickenmessung mittels Scanning Laser Polarimetrie (GDx™). Die erhobenen Blutflussparameter, wie Pulsamplitude, Pulsvolumen sowie POBF wiesen keine Unterschiede zwischen den Grupppen auf (p>0.004). Ein negativer Zusammenhang ergab sich zwischen dem intraokularen Druck und dem POBF für das Gesamtkollektiv und die Gruppe der Normalaugen. Von den globalen GDx™ Parametern konnte eine positive Korrelation zwischen der „Ellipse Modulation“ und dem POBF festgestellt werden.
Die Messung des pulsatilen okulären Blutflusses dürfte eine weitere wesentliche Information bei der Diagnostik und in der Verlaufskontrolle von Glaukomen liefern. Ein erhöhtes okulär-vaskuläres Risiko bei Patienten mit Pseudoexfoliation ließ sich mit dieser Untersuchungsmethode jedoch nicht nachweisen.
Summary
Pseudoexfoliation syndrome (PEX) is one of the most frequently diagnosed causes of open-angle glaucoma and has been shown to be statistically significantly associated with a high risk of hypertension, angina, myocardial infarction or stroke and retinal vein thrombosis. The aim of this study was to evaluate the pulsatile ocular blood flow (POBF) in pseudoexfoliation syndrome with and without glaucoma.
Eleven eyes with pseudoexfoliation syndrome without glaucoma, 11 with a diagnosis of PEX-glaucoma and seven normal eyes of age-matched controls were enrolled. A complete ophthalmological examination included measuring the POBF with the Langham pneumotonometer as well as the determination of the nerve fiber layer thickness by scanning laser polarimetry (GDx™). There was no difference for the blood flow parameters, pulse amplitude, pulse volume or POBF between the groups (p>0.004). A negative correlation between the intraocular pressure and the POBF was found for all eyes. Out of the GDx™ parameters analysed „ellipse modulation“ was significantly correlated with POBF.
Measurements of the POBF are an additional option for the diagnosis and the follow-up of glaucoma. None of the parameters that are measured by the POBF showed a correlation with the presence of pseudoexfoliation, however.
