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

[edit] Branches

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

[edit] Orbital group

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

[edit] Ocular group

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

[edit] Blood supply

Branches of the ophthalmic artery supply:

[edit] 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]
