Which of the following veins is NOT a systemic vein of the eye?

The superior cruciate vein is not classified as a systemic vein of the eye. This vein does not have a significant role in the venous drainage of the eye compared to the other options provided.

The inferior ophthalmic vein and the transverse sinus are important for draining blood from the eye and surrounding structures back to the systemic circulation. The inferior ophthalmic vein specifically drains the ocular structures, while the transverse sinus is a major venous channel that receives blood from multiple sources, including the eye region. The occipital sinus, although located at the back of the skull, is also involved in the drainage of venous blood but is generally not considered part of the localized drainage of the eye.

By identifying the superior cruciate vein as the exception, we recognize that it does not participate in the systemic venous drainage pertinent to the eye’s vascular system. This understanding is critical for those studying the anatomy and physiology related to ophthalmology and phlebotomy technician practices.
