Relationships between the arteries and veins and the connective tissue system in the human orbit.
From 60 mu histological serial sections, we learned that retrobulbarly in the orbit there is a marked difference between the relationships of the arteries on the one hand, and the veins on the other, to the connective tissue system. In addition, areas with a relatively high arterial density could be differentiated from areas with a relatively high venous density. These morphological and topographical differences may be of significance to the optimal functioning of the whole of the visual apparatus, of which the vascular system forms an integrated part. In the next article we will see whether or not these very specific relationships are the same in bulbar parts of the orbit.
