- Source: Vorticose veins
The vorticose veins, referred to clinically as the vortex veins, 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.
Vorticose veins are an important ophthalmoscopic landmark.
Structure
= 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.
Clinical significance
Vorticose veins are an important ophthalmoscopic landmark. They can be visualised in a dilated pupil using an indirect ophthalmoscope.
