Orthogonal polarization spectral (OPS) imaging is a new clinical technique for observation of the microcirculation of organ surfaces. For validation purposes, we compared OPS images of the nailfold skin with those obtained from conventional capillary microscopy at rest and during venous occlusion in 10 male volunteers. These images were computer analyzed to provide red blood cell velocity and capillary diameters of the same nailfold capillaries at rest and during venous occlusion. Results…

Orthogonal polarization spectral imaging of conjunctival microcirculation
TLDR
OPS imaging can be used to measure the diameters of microvessels, functional capillary density, and other parameters, which indicates the necessity of using a standardized approach to examine the conjunctival vasculature.

A microscope-television system for studying flow velocity in human skin capillaries.
TLDR
The technique can be used in clinical practice for studying the physiology and pathophysiology of cutaneous micro Circulation in man and may become an important diagnostic tool in diseases that involve disturbances of the microcirculation, such as diabetes, hypertension, and atherosclerosis.
In vivo comparison of the nailfold capillary diameter as determined by using the erythrocyte column and FITC-labelled albumin.
TLDR
No extravasation of FITC-HA was observed neither before nor after venous occlusion, and the difference of 405 microns between the full capillary lumen as represented by the fluorescent plasma space and the width of the ec-columns corresponds presumably to the plasmatic zone between red cells and the vessel wall.
Hemodynamics in nailfold capillaries of patients with systemic scleroderma: synchronous measurements of capillary blood pressure and red blood cell velocity.
TLDR
In patients with systemic scleroderma and in healthy volunteers matched for age and sex, capillary blood pressure was measured by direct cannulation and capillary red blood cell velocity by video microscopy and a strong correlation showed that the pressure gradient across the capillary loop was mainly dependent on precapillary resistance.

[Cap image--a new kind of computer-assisted video image analysis system for dynamic capillary microscopy].
TLDR
A newly developed multi-function video image analysis system for the computer-aided evaluation of capillaroscopic findings in microcirculation research makes it possible not only to measure numerous morphological parameters such as capillary diameter, length, torquation index and capillary density, but also to perform video densitometric analysis, for example using fluorescent dyes.
The influence of hydrostatic pressure and contralateral cooling on capillary blood cell velocity and transcutaneous oxygen tension in fingers.
TLDR
The pTcO2 findings indicate that the skin vasculature under the isothermally heated (44 degrees C) sensor is dilated and does not respond to vasoconstrictor stimuli.
Mechanisms for edema formation in normal pregnancy and preeclampsia evaluated by skin capillary dynamics.
TLDR
It is suggested that vasomotor activity may serve as a physiological modulator of vascular resistance and hence CBV, and its response to increased transmural pressure induced by venous occlusion in healthy subjects, normal pregnancies and patients with preeclampsia.
