Individuals with cortical visual impairment (CVI) present with a unique collection of visual and behavioral characteristics. These characteristics provide the foundation for specialized assessment using The CVI Range which determines the degree or level of functional vision. The scores derived from The CVI Range are then used to guide interventions and accommodations that are applied to meaningful routines of the day. This presentation will provide an overview of these principles. Photo and video examples will be used to illustrate key concepts.
