Hnatko K. Structural-functional features of adaptive-compensational processes in the eye-ball vessel bed by the toxic retina dystrophy

In the experiment on the retina dystrophy it is shown that in the conditions of the under proof pathology the structural-dimensional organization of the eye-ball vessel bed is being considerably changed, it is characterized by the decrease of the diameters of main arterial trunks and their branches, the increase of the angles of arterial vessels branching out, the growing fatter of the artery walls, the narrowing of their lumen, the violation of the nucleus-cytoplasmatic relations in the endothelial cells. The experimental retina dystrophy caused the distension of venous trunks and their branches, the increase of the angles of the venous vessels confluence. In the modeled pathology conditions the marked structural reconstruction of the haemomicrocirculational channel. The dystrophic retina correction by perftoran improves the eye-ball blood supply at the cost of the arteries lumen enlargement, the decrease of the structural changes of the vessels’ walls, the improvement of the haemomicrocirculation.
