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

[edit]

Course and relations

[edit]

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

Fate

[edit]

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

Variation

[edit]

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

[edit]

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