Journal ArticleDOI
Increased Wall:Lumen Ratio of Retinal Arterioles in Male Patients With a History of a Cerebrovascular Event
Joanna Harazny,Martin Ritt,D. Baleanu,Christian Ott,Josef G. Heckmann,Markus P. Schlaich,Georg Michelson,Roland E. Schmieder +7 more
TL;DR: Assessment of wall:lumen ratio of retinal arterioles emerged as an attractive tool to identify treated patients with hypertension with increased cerebrovascular risk.
Journal ArticleDOI
Analysis of retinal arteriolar structure in never-treated patients with essential hypertension.
Martin Ritt,Joanna Harazny,Christian Ott,Markus P. Schlaich,Markus P. Schneider,Georg Michelson,Roland E. Schmieder +6 more
TL;DR: The changes in arteriolar structure of retinal vessels in never-treated patients with essential hypertension revealed a similar pattern to that observed previously by other investigators in subcutaneous small arteries in essential hypertension.
Journal ArticleDOI
Wall-to-lumen ratio of retinal arterioles and arteriole-to-venule ratio of retinal vessels in patients with cerebrovascular damage.
TL;DR: The increase in WLR and WCSA of retinal arterioles, as well as in IMT in patients with cerebrovascular damage suggests vascular hypertrophy in the microvascular and macrovascular bed.
Journal ArticleDOI
Measurement of kidney perfusion by magnetic resonance imaging: comparison of MRI with arterial spin labeling to para-aminohippuric acid plasma clearance in male subjects with metabolic syndrome.
Martin Ritt,Rolf Janka,Markus P. Schneider,Petros Martirosian,Joachim Hornegger,Werner Bautz,Michael Uder,Roland E. Schmieder +7 more
TL;DR: Perfusion measurement of a single coronal kidney slice by MRI-ASL is able to approximate kidney perfusions and to approximate changes in kidney perfusion due to pharmacological intervention.
Journal ArticleDOI
New software analyses increase the reliability of measurements of retinal arterioles morphology by scanning laser Doppler flowmetry in humans.
Joanna Harazny,Ulrike Raff,Jürgen Welzenbach,Christian Ott,Martin Ritt,Marina Lehmann,Georg Michelson,Roland E. Schmieder +7 more
TL;DR: The new software ‘SLDF version 4.0’ clearly improved the reliability of assessing the structural parameters of the retinal arterioles as well as the interobserver and intraobserver reliability.
