Contributor: Jesse Vislisel, MD, The University of Iowa 71-year-old woman presenting with a cilioretinal artery occlusion. Note the retinal whitening secondary to inner retinal edema in the distribution of cilioretinal artery perfusion. There is a prominent cherry-red spot due to intact choroidal circulation.

Cilioretinal artery occlusion (CLRAO) often occurs in the setting of a central retinal vein occlusion (CRVO). This lack of perfusion in the cilioretinal artery results from a functional hemodynamic block as the low perfusion pressure of the choroid, which supplies the cilioretinal artery, is unable to overcome the elevated venous pressure which results from the CRVO.

Central retinal artery occlusion (CRAO) occurs when occlusion of the central retinal artery, a branch of the ophthalmic artery, results in infarction of the inner retina with subsequent, typically severe, vision loss. The picture above exhibits a CRAO with sparing of the foveal retina due to the presence of a cilioretinal artery.

2014年1月24日 · 34-year-old female diagnosed with Bartonella neuroretinitis and cilioretinal artery occlusion of the left eye. She presented with a "gray spot" in her vision. Exam revealed an RAPD OS. Photos demonstrate appearance on presentation, 1 week, 3 weeks, 4 weeks, and 8 weeks after presentation.

2020年4月14日 · DISCUSSION Introduction Retinal artery occlusion occurs when an artery in the retina is blocked, most commonly due to emboli. Occlusion of the central retinal artery (CRAO), a branch of the central retinal artery (BRAO), or the cilioretinal artery (CLRAO) may occur.

Neuroretinitis 2: Bartonella Neuroretinitis Contributor: Jeffrey Welder, MD 34-year-old female diagnosed with Bartonella neuroretinitis and cilioretinal artery occlusion of the left eye. She presented with a "gray spot" in her vision. Exam revealed an RAPD OS. Photos demonstrate appearance on presentation, 1 week, 3 weeks, 4 weeks, and 8 weeks after presentation. Patient was treated with oral ...

The inner layers of the retina gain their blood supply from the central retinal artery, and in some cases, the fovea is supplied by the cilioretinal artery. Patients with an embolism may be asymptomatic, like this patient, when a peripheral arteriole is occluded.

2010年7月7日 · Discussion Pathophysiology A retinal artery macroaneurysm (RAMA) is usually described as an idiopathic, acquired dilation of a major retinal arteriole. Typically these develop within its first three bifurcations, at branch points, or areas of arteriovenous crossing. The most commonly reported site for RAMAs is the superotemporal arteriole. Less commonly they may develop from the cilioretinal ...

2011年11月3日 · Optic disc swelling associated with cilioretinal artery occlusion: If this combination is seen during the early stages of AION, that is very strongly suggestive of arteritic AION. [11-14] It is practically non-existent in non-arteritic AION.
