Ophthalmic artery

Ophthalmic artery

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

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:

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.
