Vorticose Veins

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.

Anatomical terminology [edit on Wikidata]

Vorticose veins are an important ophthalmoscopic landmark.

Course and relations

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

Fate

Upper vortex veins empty into the superior ophthalmic vein, and lower vortex veins empty into the inferior ophthalmic vein.

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 with at least one vein in each quadrant.

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