Cortical Visual Impairment
Topics in Deafblindness - Cortical Visual Impairment (CVI)
Roughly one-third of students on the Georgia Sensory Assistance Project are diagnosed with cortical vision impairment (CVI). CVI refers to a brain condition, not an eye condition and results from damage to the visual systems in the brain that deal with processing and integrating visual information. CVI can be a temporary or permanent impairment and can range from severe visual impairment to total blindness. Due to CVI being a neurological impairment, vision is more severely reduced than can be explained by an eye exam. The degree of the impairment depends on the age of onset as well as the location and severity of the impairment in the visual pathway. CVI is referred to by many different names including cortical blindness, cerebral blindness, central visual disturbance, and cerebral visual impairment.

CVI Training Materials (West Virginia Department of Education)
West Virginia educators took part in a training series with Dr. Christine Roman-Lantzy and these materials are the result of that training on Dr. Roman-Lantzy's groundbreaking work on CVI including the CVI Range –an assessment of how CVI is impacting a child's use of vision, and ideas for intervention strategies for children at different levels on the Range. The website includes a 40 minute overview of CVI, interviews with doctors describing characteristics of CVI and an explanation of the CVI Range.
