WebNational Center for Biotechnology Information WebEditor,—Combined occlusion of the central retinal vein and the central retinal artery or a cilioretinal artery is unusual. There have been many previously reported systemic and ocular associations. The pathogenesis of this condition, however, is not established and remains controversial. Whether the venous obstruction or the arterial blockage acts as …

Cilioretinal artery occlusion - PubMed

WebTen patients, all younger than 50 years of age, had a temporal cilioretinal artery occlusion associated with a nonischemic central retinal vein occlusion. On fluorescein angiography, the cilioretinal artery eventually filled in all but one eye. The cilioretinal artery showed pulsations on fluorescein angiography in five eyes. WebCilioretinal arteries belong to the posterior ciliary artery system. They arise either directly from the choroid or from one of the posterior ciliary arteries, providing additional or alternative blood supply to the retina. Usual location is the edge of the optic nerve head, most commonly on the temporal side. Retinal artery occlusion may occur in any of the vessels supplying the eye. The main artery that supplies the eye and surrounding structures is the ophthalmic artery. The central retinal artery is the first branch of the ophthalmic artery, and it supplies nerve fibers in the optic nerve as well as the inner layers of the retina. … See more The risk factors and demographics of retinal artery occlusion are similar to ischemic stroke and include several modifiable risk … See more Obstruction of the retinal vascular lumen by an embolus, thrombus or inflammatory/ traumatic vessel wall damage or spasm.
