Caption: FIGURE 5: Fluorescein angiography image in the left eye at (a) initial visit demonstrating loss of small
capillaries, but nonperfusion areas were not observed.
Typically, PVOD shows dilated
capillaries without proliferation, as well as small veins blocked by organizing thrombi rather than infiltrating
capillaries.
Microvilli in the
Capillaries of Mammals and Birds.
The mature intermediate villi contain supplying arterioles, thin
capillaries and venules.
The tortuosity of the
capillaries in healthy subjects showed a score=0 in 15 patients; score=1 in 5 patients.
The performance of both
capillaries were quantified based on two major responses:
For longer
capillaries, higher numbers of elements, as many as 35 000 elements, were employed.
Particles were localized within epithelial and endothelial cells, within fibroblasts and between collagen fibrils in the connective tissue, within blood
capillaries, and even within RBCs (Figure 1).
The geometric shapes used included 50-[micro]m diameter posts, 100-[micro]m notches, and connecting
capillaries with 10- to 200-[micro]m cross-sectional diameters (Fig.
These
capillaries actually "leak" blood that begins to oxidize (through a process called hemoglobin degradation) ...
The new version has several enhancements, including the ability to measure capillary wear and incorporate it in pass/fail criteria, the ability to measure angled
capillaries and to inspect spinnerettes that may have damage-preventive coatings.
(1) They usually originate in the
capillaries, but they sometimes arise in the venous vessels, as well.
