central retinal vein in dogs

The central retinal vein (retinal vein) is a short vein that runs through the optic nerve and drains blood from the capillaries of the retina into the larger veins outside the eye. The anatomy of the veins of the orbit of the eye varies between individuals, and in some the central retinal vein drains into the superior ophthalmic vein, and in some it drains directly into the cavernous sinus.

What the central retinal vein is

The central retinal vein (retinal vein) is a short vein that runs through the optic nerve and drains blood from the capillaries of the retina into the larger veins outside the eye. The anatomy of the veins of the orbit of the eye varies between individuals, and in some the central retinal vein drains into the superior ophthalmic vein, and in some it drains directly into the cavernous sinus. [WP,unvetted]. The atlas records it as a vein at the organ scale in the dog.

Where the central retinal vein is

It sits in the head, within the cardiovascular and sensory systems. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the central retinal vein connects to

The atlas records 8 typed relationships for it, across 4 kinds of connection. part of camera-type eye, craniocervical region and vasculature, and 1 more.

Supply and innervation

Venous drainage: venous dural sinus.

Also called

Also recorded as retinal vein and vena centralis retinae. Searching any of those names reaches this page.

Questions

Where is the central retinal vein?

What does the central retinal vein connect to?

Part of: camera-type eye, craniocervical region, vasculature and venous system.

Is the central retinal vein the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
