The vorticose veins, referred to clinically as the vortex veins, [1] are veins that drain the choroid of the eye. There are usually 4-5 vorticose veins in each eye, with at least one vorticose vein per each quadrant of the eye. Vorticose veins drain into the superior ophthalmic vein, and inferior ophthalmic vein. [2]
The human eye is a sensory organ in the visual system that reacts to visible light allowing eyesight. ... Ophthalmic vein, 40. Vorticose vein. 41. Ethmoid bone, 42.
Ophthalmic veins are veins which drain the eye. More specifically, they can refer to: Superior ophthalmic vein; Inferior ophthalmic vein
The central retinal vein (retinal vein) is a vein that drains the retina of the eye.It travels backwards through the centre of the optic nerve accompanied by the central retinal artery before exiting the optic nerve together with the central retinal artery to drain into either the superior ophthalmic vein or the cavernous sinus.
The superior ophthalmic vein is a vein of the orbit that drains venous blood from structures of the upper orbit. It is formed by the union of the angular vein , and supraorbital vein . It passes backwards within the orbit alongside the ophthalmic artery , then exits the orbit through the superior orbital fissure to drain into the cavernous sinus .
It merges with the angular vein to form the superior ophthalmic vein. [1] [2] Previous to its junction with the angular vein, it passes through the supraorbital notch into the orbit around the eye. [1] As this vessel passes through the notch, it receives the frontal diploic vein through a foramen at the bottom of the notch.
The optic disc in a normal human eye carries 1–1.2 million afferent nerve fibers from the eye toward the brain. The optic disc is also the entry point for the major arteries that supply the retina with blood, and the exit point for the veins from the retina.
From there, the aqueous humor exits the eye through the trabecular meshwork into Schlemm's canal (a channel at the limbus, i.e., the joining point of the cornea and sclera, which encircles the cornea [7]). It flows through 25–30 collector canals into the episcleral veins.
