The ophthalmic artery is a branch of the internal carotid artery which supplies branches to supply the eye and other structures in the orbit. It enters the orbit together with the Optic nerve through the Optic canal.

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

Further information: Ocular ischemic syndrome

Severe occlusion of the ophthalmic artery causes ocular ischemic syndrome. 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]

Even complete occlusion of the ophthalmic artery may possibly leave the eye without symptoms, probably because of circulatory anastomoses [2]
