The ophthalmic artery is a branch of the internal carotid artery which supplies branches to supply the eye and other structures in the orbit.

Branches

The branches of the ophthalmic artery are often subdivided into an orbital group and an ocular group [1].

Orbital group

The orbital group, distributing vessels to the orbit and surrounding parts, includes:

Ocular group

The ocular group, distributing vessels to the eye and its muscles, includes:

Blood supply

Branches of the ophthalmic artery supply:

Occlusion

As with central retinal artery occlusions, ophthalmic artery occlusions may result from systemic cardiovascular diseases; however, a cherry red spot is typically absent and the vision is usually worse. Amaurosis fugax is a temporary loss of vision that occurs in two conditions which cause a temporary reduction in ophthalmic artery pressure: orthostatic hypotension and positive acceleration.[1]

In human anatomy, the internal carotid artery is a major artery of the head and neck that helps supply blood to the brain.

Classification

Terminologia Anatomica currently breaks the artery into four parts: "cervical", "petrous", "cavernous", and "cerebral".

The lacrimal artery arises close to the optic foramen, and is one of the largest branches derived from the ophthalmic artery: not infrequently it is given off before the artery enters the orbit.
..... Click the link for more information.
The supraorbital artery is an artery of the head.

Course

It springs from the ophthalmic artery as that vessel is crossing over to the medial side of the optic nerve.
..... Click the link for more information.
The posterior ethmoidal artery is an artery of the head. It is smaller than the anterior ethmoidal artery, branches off from the ophthalmic artery when it reaches the medial wall of the orbit.
..... Click the link for more information.
The anterior ethmoidal artery, also anterior ethmoid artery is an artery of the head.

Course

It accompanies the nasociliary nerve through the anterior ethmoidal canal, supplies the anterior and middle ethmoidal cells and frontal sinus, and enters the cranium

The medial palpebral arteries (internal palpebral arteries) are arteries of the head. They are two in number, superior and inferior, arise from the ophthalmic, opposite the pulley of the Obliquus superior.

The supratrochlear artery (or frontal artery), one of the terminal branches of the ophthalmic artery, branches off where the ophthalmic travels posterior to the trochlea.

The dorsal nasal artery (nasal artery) is an artery of the head. It is one of the two terminal branches of the ophthalmic artery.

Course

It emerges from the orbit above the medial palpebral ligament, and, after giving a twig to the upper part of the lacrimal sac,

The long posterior ciliary arteries are arteries of the head. They are two in number.

Course

They pierce the posterior part of the sclera at some little distance from the optic nerve, and run forward, along either side of the eyeball, between the sclera and choroid, to

The short posterior ciliary arteries from six to twelve in number, arise from the ophthalmic as it crosses the optic nerve.

Course and target

They pass forward around the optic nerve to the posterior part of the eyeball, pierce the sclera around the entrance of the optic

The anterior ciliary arteries are derived from the muscular branches of the Ophthalmic Artery.

Course

They run to the front of the eyeball in company with the extraocular muscles, form a vascular zone beneath the conjunctiva, and then pierce the sclera a short distance

The central retinal artery (retinal artery) branches off the ophthalmic artery, running inferior to the optic nerve within its dural sheath to the eyeball.

The superior ophthalmic vein begins at the inner angle of the orbit in a vein named the nasofrontal which communicates anteriorly with the angular vein; it pursues the same course as the ophthalmic artery, and receives tributaries corresponding to the branches of that vessel.

The inferior ophthalmic vein begins in a venous net-work at the forepart of the floor and medial wall of the orbit; it receives some veins from the Rectus inferior, Obliquus inferior, lacrimal sac and eyelids, runs backward in the lower part of the orbit and divides into two

Eyes are organs of vision that detect light. Different kinds of light-sensitive organs are found in a variety of organisms. The simplest eyes do nothing but detect whether the surroundings are light or dark, while more complex eyes can distinguish shapes and colors.

In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated.

It can also mean the skin which surrounds the eye of a bird.

In the adult human, the volume of the orbit is 30 ml, of which the eye occupies 6.5 ml.
