What is CVI?

Cortical Visual Impairments

Cortical Visual Impairment Book by Christine Roman-Lantzy.

Cortical Visual Impairment (CVI) is one of "the most common causes of visual impairment for children in the USA" (Corn & Erin, Eds., 2010). According to Roman-Lantzy (2018), CVI describes a type of visual impairment where parts of the brain may have sustained an injury or have a neurological condition that affects the visual system causing a difficulty with accessing the visual aspects of the world which impacts education and learning (Roman-Lantzy, 2018). CVI is not associated with the eye itself (Roman-Lantzy, 2018). 

CVI may also be referred to as Cerebral Visual Impairment but it is not the same. 

Be sure to consult with your qualified Teacher for Students with Visual Impairments (TSVI) if your student has CVI. Your TSVI will be able to help you develop an appropriate program with activities that will be helpful in addressing the visual and behavioural characteristics associated with CVI.

The following learning resources focus on supporting students who have CVI.
