[1] [2] Restated, "because of the brief interval between the transient event and a stroke or blindness from temporal arteritis, the workup for transient monocular blindness should be undertaken without delay." If the patient has no history of giant cell arteritis, the probability of vision preservation is high; however, the chance of a stroke ...
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.
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 ...
The size of the monocular scotoma is 5×7 degrees of visual angle. A scotoma can be a symptom of damage to any part of the visual system, such as retinal damage from exposure to high-powered lasers, macular degeneration, and brain damage. The term scotoma is also used metaphorically in several fields.

A transient ischemic attack (TIA), commonly known as a mini-stroke, is a temporary (transient) stroke with noticeable symptoms that end within 24 hours. A TIA causes the same symptoms associated with a stroke, such as weakness or numbness on one side of the body, sudden dimming or loss of vision, difficulty speaking or understanding language or slurred speech.
Temporary blindness, a type of non-permanent vision loss, may refer to: Amaurosis fugax, or fleeting blindness; Conversion disorder, formerly called hysterical blindness; Flash blindness, caused by exposure to high-intensity light.
Retinal migraine is associated with transient monocular visual loss in one eye lasting less than one hour. [1]During some episodes, the visual loss may occur with no headache and at other times throbbing headache on the same side of the head as the visual loss may occur, accompanied by severe light sensitivity and/or nausea.
