Cortical visual impairment (CVI) is a neurological form of visual
impairment which has unique implications for functional vision. CVI is the most
prevalent cause of childhood visual impairment in the U.S. (Chang & Borchert,
2021); however, it is a condition that is underreported, underdiagnosed, and

functional vision of individuals with CVI along a Range of visual functioning,
