What is the blood supply to the retina?

Question

I am too angry to find it myself. thankyou i have had a rough day x

Answer 1

Grey Doc is right. The internal carotid does travel through the cavernous sinous, and the ophtalmic artery branches off shortly thereafter.

Answer 2

The above answer is not quite completely accurate.

The cavernous sinus is a vein, not an artery.It receives the venous drainage from the ophthalmic vein amongst others. The cavernous portion of the internal carotid artery is that part which passes through the base of the skull (carotid canal / foramen lacerum)The cavernous sinus also passes through the same foramen but they do not connect.

Answer 3

The ophthalmic artery arises from the internal carotid just as that vessel emerges from the cavernous sinus. It enters the orbital cavity via the optic foramen where it has twelve branches, one of which is the central artery of the retina. Sometimes the central artery of the retina is a branch of the lacrimal artery rather than the larger ophthalmic artery itself.

Hope your day goes better.
