According to these researchers, some of the primary differences include:
Children with CVI often show a head turn when they look at or reach for an object of interest; they seem to look and then look away as they reach for the object. Children with ocular visual impairment look and reach at the same time. (Groenveld 1993)
Children with CVI -foreground/background perception. Difficulty looking for objects against patterned background or objects spaced closely together. Distance viewing difficulty
For children with ocular visual impairment, improved functioning is seen with enhanced visual input, but for children with CVI, enhanced input often is detrimental to the use of their vision.
The functional vision assessments currently used in the field rely on the needs of children with ocular impairment and do not take into account the unique characteristics of children with CVI.
Roman-Lantzy developed a functional vision assessment for children with CVI, The CVI Range (Roman-Lantzy, 2007).
