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
editCourse and relations
editVorticose veins exit the eyeball 6 mm posterior to its equator.[2]
Fate
editUpper vortex veins empty into the superior ophthalmic vein, and lower vortex veins empty into the inferior ophthalmic vein.[2][4]
Variation
editThe 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
editVorticose veins are an important ophthalmoscopic landmark.[3] They can be visualised in a dilated pupil using an indirect ophthalmoscope.[2]
