Cortical Visual Impairments (CVI)

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 my have sustained an injury or have a neurological condition that affects the visual system. CVI is not associated with the eye itself (Roman-Lantzy, 2018). Children with CVI have difficulty accessing the visual aspects of the world around them, impacting education and learning (Roman-Lantzy, 2018).

Be sure to consult with your qualified Teacher for Students with Visual Impairments (TSVI) if your student has CVI. The 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.
