In the context of stroke symptoms, what is an example of a transient visual disturbance?

Amaurosis fugax is characterized by a temporary loss of vision, often described as a curtain or shade coming down over the visual field. It typically occurs due to transient ischemia in the retina and is considered a significant indicator of potential stroke. This phenomenon is usually brief, lasting only a few minutes and resolving on its own, which fits the definition of a transient visual disturbance associated with stroke symptoms.

In contrast, Horner's syndrome involves a combination of symptoms including ptosis (drooping of the upper eyelid), miosis (constricted pupil), and anhidrosis (lack of sweating), which results from disruption of sympathetic nerve pathways but does not specifically involve transient visual disturbances. A transient ischemic attack refers to temporary neurological symptoms, but it is broader than just visual disturbances and can encompass various other symptoms. Visual agnosia is a condition characterized by an inability to recognize objects or faces despite having intact vision, which is not transient and does not fit the acute nature of visual disturbances associated with stroke symptoms.
