ABSTRACT
This investigation was aimed at the study of peculiarities of of lymphatic bed of organ of vision in herbivorous (cattle) and predatory (dog) animals, which have some anatomical differences in the eye structure. The methods of preparation, morphometry, light and electron microscopy were used. It was found that in the cattle, lymphatic capillaries of the sclera have lower density of distribution than those in dogs. In the cattle, extraorgan lymphatic vessels of lower and upper eyelids could be subdivided into a lateral and medial groups. The former group drains into parotid lymph node, while the latter group is connected to a mandibular one. In dogs an additional pathway of lymph transport was found that carried the lymph through the extraorgan lymphatic vessels into the facial lymph node.
