Abstract

The orbital venous system is complex, highly variable, and confusing. In the orbit, unlike other parts of the body, there is no direct correspondence between the arteries and veins, except for the superior ophthalmic vein which has some correspondence with the ophthalmic artery. Also, the orbital veins, unlike the orbital arteries, have a highly variable and inconstant pattern and formation of venous networks at several places, resulting in marked uncertainty and controversy as to their number, nomenclature, and pattern. The latest detailed studies on the orbital venous system are those of Henry [1] and Cheung and McNab [2].
