What is cortical visual impairment (CVI)?

Cortical visual impairment (CVI) refers to vision loss that originates from abnormalities in the brain rather than issues with the eyes themselves. Unlike other forms of visual impairment that may stem from structural problems or diseases affecting the eye, CVI is a neurological condition where the brain has difficulty processing visual information. This condition can result from various factors, including brain damage, developmental disorders, or strokes that affect the areas responsible for vision in the brain.

Understanding CVI necessitates recognizing that the visual pathways are functional, but the processing capabilities are compromised. Individuals with CVI may experience a range of visual difficulties, such as problems with visual perception, difficulty in recognizing objects, or challenges with visual attention. Thus, this answer accurately captures the essence of cortical visual impairment as it relates directly to brain function rather than the anatomy of the eyes or external light conditions.
