  • Risk factors for ischemic cerebral stroke in patients with acute amaurosis fugax. [Journal Article]
    Can J Ophthalmol. 2022 Nov 08 [Online ahead of print]Chen TY, Uppuluri A, … Bhagat N
  • CONCLUSIONS: Ischemic stroke and myocardial infarction were diagnosed in 0.3%-0.9% of hospitalized acute AF cases. Presence of hypercoagulable state, systemic vasculitis, CAD, and atherosclerosis each individually increased the risk of ischemic stroke by more than 3-fold; patients with these risk factors and acute AF should be closely monitored for developing acute systemic thrombotic events.
  • Ocular Migraine With Amaurosis Fugax of the Left Eye: A Case Report. [Case Reports]
    Cureus. 2022 Aug; 14(8):e28272.Tazin F, Kumar H, … Go CC
  • In amaurosis fugax, there is a sudden loss of vision in one eye. Patients gain their vision after a few minutes. The most common underlying cause is atherosclerosis of the internal carotid artery. Other underlying causes include vasospasm of the internal carotid artery, which leads to hypoperfusion and is seen in vasculitis, ocular migraines, and systemic lupus erythematosus. In this case study, …
  • [Unique visual symptom of amaurosis fugax: a case report]. [Case Reports]
    Rinsho Shinkeigaku. 2022 Sep 28; 62(9):722-725.Terashi A, Takada T, Ajiki M
  • We describe an unusual case of a 73-year-old man with amaurosis fugax. He had repeated transient monocular symptoms, one of which features lighting bolt-shaped glittering in the full visual field of the right eye since medical treatment for hypertension and diabetes mellitus started. A few days later, he felt difficulty in speech as well as sensory and motor disturbance in the left upper extremit…

  • The ophthalmic artery is the first branch of the internal carotid artery. It comes off just distal to the cavernous sinus. The ophthalmic artery gives off many branches, which supply the orbit, meninges, face, and upper nose. When the ophthalmic artery is occluded, it can compromise vision. The ophthalmic artery comes off the internal carotid artery on the medial side of the anterior clinoid proc…

  • The term amaurosis fugax is often used interchangeably to describe transient visual loss (TVL). However, it is employed widely in medicine to refer to any cause of transient monocular visual loss. Here, we will refer to amaurosis fugax only in the context of transient monocular visual loss associated with vascular thromboembolic events arising from the internal carotid arterial system. [1],[2],[3…

  • Determining the difference between hemodynamic and embolic stroke in the presence of chronic internal carotid artery occlusion is important. Embolic symptoms may be from classic stroke or transient ischemic attack (TIA). Symptoms may include a contralateral motor or sensory deficits as well as amaurosis fugax. Hemodynamic symptoms may be similar to a classic stroke or TIA, but may also be less pr…

  • Symptoms of extracranial carotid disease are most often caused by embolization. Arterial emboli account for approximately one-quarter of strokes in Europe and North America, and 80% of these originate from atherosclerotic lesions in a surgically accessible artery in the neck. The most common lesion is at the bifurcation of the carotid artery. Transcranial Doppler studies have shown that emboli ar…
  • Lights Off, Lights On: Amaurosis Fugax in Polycythemia. [Case Reports]
    Cureus. 2022 Jun; 14(6):e25752.Tan SS, Samsudin A, … Nurul-Ain M
  • There are many causes of amaurosis fugax, including polycythemia. Polycythemia is associated with elevated hematocrit levels and hyperviscosity, which can lead to ocular manifestations. We report a polycythemia patient with amaurosis fugax, who had resolution of ocular symptoms following venesection. A 29-year-old gentleman presented with a six-month history of episodic bilateral transient loss o…
  • 18F-NaF PET/MRI for Detection of Carotid Atheroma in Acute Neurovascular Syndrome. [Journal Article]
    Radiology. 2022 10; 305(1):137-148.Kaczynski J, Sellers S, … Williams MC
  • Background MRI and fluorine 18-labeled sodium fluoride (18F-NaF) PET can be used to identify features of plaque instability, rupture, and disease activity, but large studies have not been performed. Purpose To evaluate the association between 18F-NaF activity and culprit carotid plaque in acute neurovascular syndrome. Materials and Methods In this prospective observational cohort study (October 2…
  • Carotid Stump Syndrome With Stent-Assisted Coil Embolization. [Case Reports]
    Cureus. 2022 Mar; 14(3):e22746.Baker C, Sherrod B, … Grandhi R
  • Carotid stump syndrome (CSS) is a rare cause of recurrent ipsilateral cerebrovascular events that typically manifests as transient ischemic attacks or amaurosis fugax. The cause of these recurrent symptoms is thought to be microembolization from an occluded internal carotid artery that reaches intracranial circulation through anastomoses. We undertook a systematic literature review according to P…
  • Amaurosis as an initial presentation of Takayasu arteritis in children. [Review]
    Rheumatol Int. 2022 Apr 02 [Online ahead of print]Bayardo-Gutiérrez B, Yamazaki-Nakashimada MA, … Scheffler-Mendoza SC
  • Visual disturbances in Takayasu arteritis (TA) are common but tend to be late manifestations of the disease. However, its presence at diagnosis must alert TA to avoid sight disabilities. Herein, we present two children with TA that debuted with vision loss, and the results of the literature review displayed 58 subjects with vision loss before the diagnosis of TA. The world English literature was …
  • Amaurosis Fugax: A Rare Oxaliplatin-Induced Ocular Toxicity - A Report of Three Cases. [Case Reports]
    Case Rep Oncol. 2022 Jan-Apr; 15(1):133-137.Tunio MA, Phillips K, Baker P
  • Oxaliplatin, a third-generation platinum-based agent, is a constitutive part of systemic treatment for colorectal cancer in adjuvant and metastatic settings. Ocular toxicity is an extremely rare adverse effect of Oxaliplatin. Ocular toxicities have been documented in the form of (a) common (≥1/100, <1/10) which include the conjunctivitis, unexpected lacrimation, blurry vision, blepharoptosis, and…
  • Ischemic ocular manifestations of giant cell arteritis: A Canadian case series. [Journal Article]
    J Neurol Sci. 2022 05 15; 436:120222.Issa M, Donaldson L, … Margolin E
  • CONCLUSIONS: Occult GCA occurs more commonly in older patients who most of the time present with AION. Levels of inflammatory markers were similar in the occult and systemic groups. Though ocular ischemic manifestations were similar in both cohorts, in systemic GCA involvement of multiple ocular circulations is likely more common GCA should always be considered in older patients who present with signs of retinal and/or optic nerve head ischemia (AION and/or CWS) and new onset of CNPs, especially in patients where more than one ocular arterial circulation is involved.
