2017年8月1日 · Central retinal artery occlusion (CRAO) is an ocular emergency. Patients typically present with profound, acute, painless monocular visual loss—with 80% of affected indi­viduals having a final visual acuity of counting fingers or worse.

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, the first branch of the ophthalmic artery, is the main blood supplier of the inner layers of the retina.

2017年6月15日 · The retina seemed well perfused at this point, with no emboli present; however, the patient’s symptoms, recent vascular issues and absence of other clinical findings were highly suspicious for a possible diagnosis of reperfusing central retinal artery occlusion (CRAO).

2024年5月2日 · Central retinal artery occlusion (CRAO) is an ophthalmic emergency that can lead to sudden and severe vision loss. CRAO has been defined as interruption of blood flow through the central retinal artery by thromboembolism or vasospasm with or without retinal ischemia.

2016年10月1日 · CRAO can be divided into four different subtypes: permanent nonarteritic; transient nonarteritic; nonarteritic with cilioretinal sparing; and arteritic. These subtypes are associated with different presenting VAs and different spontaneous recovery rates.

Central retinal artery occlusion (CRAO) is a rare yet serious eye condition that can lead to sudden and irreversible vision loss. First identified in the mid-19th century, CRAO occurs when the central retinal artery, which supplies oxygen-rich blood to the retina, becomes obstructed.

Central retinal artery occlusion is a devastating ocular emergency with no accepted treatment and a poor visual prognosis. This review will survey epidemiology, pathophysiology, diagnosis, and acute management.

2013年11月1日 · Central retinal artery occlusion (CRAO), or a stroke of the eye, is an ocular emergency. It represents end-organ ischemia and is analogous to terminal branch occlusion in cerebral stroke. 1

Emboli from the heart or the carotid arteries can cause ophthalmic artery occlusion (OAO), central retinal artery occlusion (CRAO) and branch retinal artery occlusion (BRAO).

Central retinal artery occlusion (CRAO) is a blockage in the central artery in your retina. Branch retinal artery occlusion (BRAO) blocks the small arteries, that branch off the central artery. What causes RAO?
