However it should be remembered that the Cilio retinal artery itself is a branch of the Short Posterior Ciliary Arteries which is derived from the Ophthalmic Artery.
12.
They combined intracranial resection, ligation of ophthalmic artery, and selective arterial ligature of the external carotid artery, but the patient did not have retinal vascular malformations.
13.
This branch, which may arise directly from the superficial temporal artery, supplies the Orbicularis oculi, and anastomoses with the lacrimal and palpebral branches of the ophthalmic artery.
14.
The Cerepress " ! measures blood pressure in the eye s central retinal vein ( CRV ) and blood velocity in the ophthalmic artery, which taken together highly correlate to intracranial pressure.
15.
On the cheek it distributes branches which anastomose with the infraorbital; after supplying the lacrimal sac and Orbicularis oculi, it ends by anastomosing with the dorsal nasal branch of the ophthalmic artery.
16.
The dorsal nasal artery runs along the nose and is the terminal branch of the ophthalmic artery, which is a terminal branch of the ICA . Many smaller branches and communications also exist.
17.
The optic canal contains the optic nerve ( cranial nerve II ) and the ophthalmic artery, and sits at the junction of the sphenoid sinus with the anterior and posterior ethmoidal foramen and zygomatic orbital foramen.
18.
The pituitary glands of these patients were believed to have been producing excessive amounts of thyroid-stimulating hormone which caused swelling in the eyesocket that could compress the optic nerve or ophthalmic artery leading to blindness.
19.
The ophthalmic artery supplies the choroid via the short posterior ciliary arteries and the retina via the central retinal artery, however, the route to the choroid is typically less circuitous than the route to the retina.
20.
Sympathetics are provided by the superior cervical ganglion and they reach the ganglion either as branches of the nasociliary nerve or directly from the extension of the plexus on the ophthalmic artery ( sympathetic branch to ciliary ganglion ).
