Amaurosis fugax (Greek: ἀμαύρωσις, amaurosis meaning 'darkening', 'dark', or 'obscure', Latin: fugax meaning 'fleeting') is a painless temporary loss of vision in one or both eyes. [ 3 ] Signs and symptoms
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Symptoms such as unilateral weakness, amaurosis fugax, and double vision have higher odds of representing TIA compared to memory loss, headache, and blurred vision. [7] Below is a table of symptoms at presentation, and what percentage of the time they are seen in TIAs versus conditions that mimic TIA.
Amaurosis fugax. Amaurosis fugax, also known as transient monocular blindness, is caused by a sudden, temporary decrease in blood flow to one eye. The loss of vision is abrupt, lasting only seconds or minutes. Blindness is total, though it is sometimes limited to a specific area of vision. Blindness frequently develops as if a shade was drawn ...
Subclavian steal syndrome (SSS), also called subclavian steal steno-occlusive disease, is a medical condition characterized by retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery. This reversal occurs due to proximal stenosis (narrowing) or occlusion of the subclavian artery.
TIAs by definition last less than 24 hours and frequently take the form of weakness or loss of sensation of a limb or the trunk on one side of the body or the loss of sight (amaurosis fugax) in one eye. Less common symptoms are artery sounds , or ringing in the ears . [6]
Uhthoff's phenomenon (also known as Uhthoff's syndrome, [1] Uhthoff's sign, [1] and Uhthoff's symptom) is the worsening of neurologic symptoms in multiple sclerosis (MS) and other demyelinating diseases when the body is overheated. This may occur due to hot weather, exercise, fever, saunas, hot tubs, hot baths, and hot food and drink.
Ischemic optic neuropathy (ION) is the loss of structure and function of a portion of the optic nerve due to obstruction of blood flow to the nerve (i.e. ischemia).Ischemic forms of optic neuropathy are typically classified as either anterior ischemic optic neuropathy or posterior ischemic optic neuropathy according to the part of the optic nerve that is affected.
