Cortical Visual Impairment
Cortical Visual Impairment is the leading cause of visual impairment in developed countries. CVI is not a condition that affects the eyes or optic nerves. CVI impacts the visual cortex in the brain. This results in the visual cortex having difficulty processing and interpreting the information that the eyes can see. CVI is most often caused by anoxia (lack of oxygen to the brain). The eyes of an infant with CVI usually look normal, although they will often not be able to visually track an object. CVI has been described as being similar to holding several (11 or 12) layers of crinkled Saran Wrap in front of your eyes. As you look around, remember that you are piecing the information togethor with a visual memory and experiential foundation that the infant has not yet acquired. CVI is also describe as being similar to looking at the world through a piece of swiss cheese. The Anchor Center for Blind Children provides extensive resources for children with CVI. You can visit their website at anchorcenter.org
