Vorticose veins
blood vessels
The vorticose veins, commonly known as the vortex veins, are veins that drain the choroid of the eye. Usually, there are four vorticose veins in each eye, but can vary up to eight in number. There is at least one vorticose vein per each quadrant of the eye, located at the lateral and medial sides of the superior and inferior rectus muscles. Vorticose veins drain into the superior ophthalmic vein, and inferior ophthalmic vein.
Vorticose veins are an important opthalmoscopic landmark.
Structure
Course and relations
Vorticose veins exit the eyeball 6 mm posterior to its equator. In typical anatomy, both upper vorticose veins empty into the superior ophthalmic vein, and both lower vorticose veins drain into the inferior ophthalmic vein.
Variation
The number of vorticose veins is known to vary from four to eight, with about 65% of the normal population having four 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.
The public source identifies “Vorticose veins” as blood vessels. This brief keeps that definition visible, then builds a research path around Vorticose, veins and blood.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Vorticose veins”, the useful work is to connect “blood vessels” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 27, 2025. The linked authority identifier is Q7941948. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
