The purpose of the present study was to investigate the contribution of basal nitric oxide (NO)
on retinal vascular tone in humans. In addition, we set out to elucidate the role of NO in …

purpose. To test the hypothesis that human choroidal blood flow (ChBF) may depend, not
only on ocular perfusion pressure (OPP), but also on absolute mean arterial pressure (MAP) …

AIM To investigate the reproducibility and sensitivity of the Zeiss retinal vessel analyser, a
new method for the online determination of retinal vessel diameters in healthy subjects. …

There is evidence from in vitro and animal studies that endothelin is a major regulator of retinal
blood flow. We set out to characterize the role of the endothelin-system in the blood flow …

Background: There is evidence that perfusion abnormalities of the optic nerve head are
involved in the pathogenesis of glaucoma. There is therefore considerable interest in the effects …

purpose. Imaging studies suggest that the choroidal vasculature may be altered in central
serous chorioretinopathy. Little is known, however, about the regulation of ocular blood flow in …

During the first counselling after the birth of a child with cleft lip and palate (CLP) information
about the malformation should be delivered and a long-standing relationship between the …

Purpose.: We compared the response of choroidal and optic nerve head blood flow (ChBF,
ONHBF) in response to an increase in ocular perfusion pressure (OPP) during isometric …

Aim: To determine the effects of various mixtures of O 2 and CO 2 on retinal blood flow in
healthy subjects. Methods: A randomised, double masked, four way crossover trial was carried …

purpose. There is evidence that the choroid has some autoregulatory capacity in response
to changes in ocular perfusion pressure (OPP). The mediators of this response are hitherto …
