Which is NOT considered a visual change associated with transient vision loss?

Cortical blindness is a condition resulting from damage to the visual processing areas of the brain, rather than a peripheral visual change. It does not involve issues within the eye itself, like retinal detachments or transient ischemic events that typically cause visual disturbances.

In contrast, amaurosis fugax refers to temporary loss of vision due to decreased blood flow to the retina, making it a recognized visual change associated with transient vision loss. Retinal detachment involves the separation of the retina from the underlying tissue, leading to sudden and permanent vision loss if not treated promptly, representing a clear visual alteration. Giant cell arteritis can lead to a vision loss scenario through ocular ischemic events as a consequence of inflammation affecting the blood vessels supplying the eyes, which can also cause visual changes.

Thus, cortical blindness, as a central phenomenon affecting visual processing rather than direct eye pathology, is accurately identified as not fitting within the definition of a visual change associated with transient vision loss.
