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.

It is an obstruction of retinal blood flow that may be due to an embolus causing occlusion or thrombus formation, vasculitis causing retinal vasculature inflammation, traumatic vessel wall damage, or spasm. The lack of oxygen delivery to the retina during the blockage often results in severe vision loss in the area of ischemic retina.

An ophthalmic artery occlusion (OAO), central retinal artery occlusion (CRAO), or, less commonly, a branch retinal artery occlusion (BRAO) can be associated with life-threatening conditions (e.g., carotid occlusive or cardiac valve disease).

2019年9月20日 · An ophthalmic artery occlusion (OAO), central retinal artery occlusion (CRAO), or, less commonly, a branch retinal artery occlusion (BRAO) can be associated with life-threatening conditions (e.g., carotid occlusive or cardiac valve disease).

2023年6月20日 · Central retinal artery occlusion (CRAO) recently has been recognized as a medical emergency that warrants rapid diagnosis and treatment, as well as assessment for cerebral stroke risk. In 2021, the American Heart Association published a scientific statement that called for the development of systems of care to prioritize the diagnosis of CRAO. 2

2021年3月8日 · Central retinal artery occlusion (CRAO) is a form of acute ischemic stroke that causes severe visual loss and is a harbinger of further cerebrovascular and cardiovascular events. There is a paucity of scientific information on the appropriate management of CRAO, with most strategies based on observational literature and expert opinion.

4 天之前 · In 2019, the American Academy of Ophthalmology (AAO) released the latest Preferred Practiced Pattern (PPP) of acute symptomatic ophthalmic artery occlusion (OAO) or CRAO that recommends an immediate referral to the nearest stroke center for prompt assessment for consideration of an acute intervention.

CRAO is an ophthalmic and medical emergency. The causes of and risk fac-tors for CRAO are similar to those of cerebrovascular events. Hence, patients with CRAO must be evalu-ated promptly for stroke to minimize secondary ischemic events. Despite the grim prognosis for CRAO, efforts to re-store vision—no matter which therapy

2018年2月3日 · Acute retinal arterial ischemia, including vascular transient monocular vision loss (TMVL) and branch (BRAO) and central retinal arterial occlusions (CRAO), are ocular and systemic emergencies requiring immediate diagnosis and treatment.

2024年7月1日 · For patients with CRAO, emergency protocols at some medical centers are achieving promising results in preserving vision and even reversing stroke events.
