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
undertreated (Roman-Lantzy, 2018). This form of visual impairment requires a
very different approach to instructional supports and environmental/material
adaptations as compared with ocular visual impairments. When provided with
appropriate, assessment-based interventions, children and youth with CVI can be
expected to demonstrate measurable progress in visual functioning over time. The
CVI Range (Roman-Lantzy, 2007; Rev. 2018) is an instrument used to assess the
functional vision of individuals with CVI along a Range of visual functioning,
