Which of the following describes Cortical Visual Impairment (CVI)?

Cortical Visual Impairment (CVI) is a condition that arises from issues in the brain rather than problems with the eye itself. It is characterized by a disruption in the visual processing pathways in the brain, causing difficulties in interpreting visual information. This means that the eyes may be healthy and functioning normally, but the brain is not able to process the visual signals effectively, leading to varying degrees of visual impairment.

This understanding highlights why the description of CVI includes the notion of a communication error between the eyes and the brain. Visual stimuli reach the retina and travel through the optic nerve to the brain's visual cortex, where interpretation occurs. In CVI, while the transmission of information might still be intact, the brain fails to make sense of what it is seeing due to damage or atypical development in the visual processing areas.

Contextually, other options do not accurately represent CVI. For instance, CVI is not primarily caused by an eye condition and is distinguishable from other forms of visual impairments that result directly from ocular issues. Additionally, while it is important to note that CVI can contribute to visual deficits, it is not the leading cause of blindness in adults—a distinction often associated with other conditions such as age-related mac
