The CVI Range Assessment (Roman, 2007, 2018) is a functional vision assessment desiged to investigate the visual and behavioral characterstics associated with CVI. It measures the degree of impact of CVI on a 0 – 10 continuium where 0 represents no visual function and 10 represents near typical visual function.

Here’s a thorough primer on what needs to happen once your child is diagnosed with Cerebral/Cortical Visual Impairment (CVI), derived from your child’s CVI visual behaviors.

Visual functioning in CVI is measured across the CVI Range (0-10), with three major phases describing level of impact of the CVI Characteristics on the individual’s ability to use her vision functionally: 0-3 Phase I Most severe impact on visual functioning; 3-7 Phase II Moderate impact on visual functioning

Christine Roman-Lantzy, PhD, defines 10 characteristics of visual behavior that are quantifiable using the CVI Range ©, which are outlined in her textbook (2007, 2018). The characteristics are visual processing functions that occur in cortices of the temporal, parietal, and probably the frontal lobe of the brain.

There are a number of purposes associated with The CVI Range. It is used to create a CVI Schedule to incorporate the principles of CVI into routines across the learning and living day. Value of Obtaining Scores. Application of CVI Range in research and practice.

The scoring guides determine a student’s range of visual function and placement within three broad phases of CVI. An educational team can then use the guidelines defined in the three phases to plan educational needs and interventions.

CVI Range scores range from 0 to 10, with 10 indicating the best functional vision. The scores are further divided into three phases (phase I: 0–3, phase II: 4–7 and phase III: 8–10; figure 1).

The CVI Range is the only educational tool to assess the degree of impact on the visual functioning of a child with CVI. Developed by Christine Roman-Lantzy, PhD, specifically for those with CVI, the CVI Range was an outgrowth of the system she used as a TVI/O&M to teach children who had been dismissed as unteachable.

unique visual/behavioral characteristics of CVI. The CVI Range is a scale with 0 representing little or no functional vision and 10 representing near normal use of vision. This scale is used to plot your child’s visual behaviors into one of three phases along the continuum. The CVI Range is a reliable and valid instrument (Newcomb, 2010).

The CVI Range is a measure used to determine the degree of impact of the visual and behavioral characteristics. The scores on The CVI Range span across three Phases, or segments correlated with progress across the zero-ten continuum.
