Anatomical terminology

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]

Vorticose veins are an important ophthalmoscopic landmark. [3]

Structure

Course and relations

Vorticose veins exit the eyeball 6 mm posterior to its equator. [2]

Fate

Upper vortex veins empty into the superior ophthalmic vein, and lower vortex veins empty into the inferior ophthalmic vein. [2] [4]

Variation

The number of vorticose veins is known to vary from 4 to 8, with about 65% of the normal population having 4 or 5 [1] with at least one vein in each quadrant. [2]

Clinical significance

Vorticose veins are an important ophthalmoscopic landmark. [3] They can be visualised in a dilated pupil using an indirect ophthalmoscope. [2]
