[Angioarchitectonics of eyeball blood vessels in the normal dog and in dogs with experimental coarctation of the aorta].
Three series of chronic experiments for production of a dosed coarctation of the aorta (1/2, 2/3 and 3/4 of its lumen) have been carried out in 96 dogs. The postoperative period in all the animals had a smooth course. After the operation, by means of functional and pathomorphological investigation architectonical peculiarities of the eye ball vessels are studied. For comparison of the changes occurring in the eye ball vessels under the given pathology, its normal blood supply has been studied in 20 dogs. At various degree of the aortal coarctation already during the first week of the experiment, certain changes develop in the vascular system of the eye ball coats: spasm of the arterioles, up to the capillaries and dilatation of the venules. Vascular convolution of various degree is revealed. The changes described are directly dependent on the degree of the aorta narrowing and duration of the experiment.
