What is referred to as Amaurosis fugax?

Amaurosis fugax is characterized by temporary, partial, or total vision loss in one eye. This phenomenon is often described as a "fleeting" loss of sight and typically resolves on its own within minutes. The condition is usually caused by transient ischemia, often related to carotid artery disease or embolism that affects the blood supply to the retina. Understanding this condition is vital, as it can be an indicator of underlying vascular issues, such as stenosis or other forms of carotid artery disease, which may increase the risk of stroke.

The other options do not accurately describe amaurosis fugax. Persistent blurred vision suggests a more chronic condition rather than a transient one, while loss of vision in both eyes or complete blindness indicates more severe and possibly irreversible damage, which differentiates them from the temporary nature of amaurosis fugax.
