Angular vein

The angular vein is a vein located between the nose root and the eye. It is created through the junction of the supratrochlear vein and the supraorbital vein. The angular vein is comparatively short and located near the eye socket's anterior angle. The angular vein continues through the face as the facial vein. In rare cases, two angular veins may result from a bifurcation of the trunk at the nose root. In this case, the two frontal veins join to make up the angular vein trunk. The angular vein receives blood from the superior, inferior palpebral, external nasal, and infraorbital veins. It drains into the superior ophthalmic vein to connect with the cavernous sinus. A varix of the angular vein may falsely appear similar to a lacrimal sac mucocoele, which is a swelling below the medial canthal tendon. Such a varix is rare but may be caused by genetic factors, trauma, tissue abnormality, or a chronic blood flow obstruction. The only risk from such a varix is a small chance of intracranial air embolus.
