Cortical Visual Impairment (CVI) is now the most common cause of visual impairment in children in the United States according to the American Printing House for the Blind's CVI page. CVI is caused by damage, injury, or trauma to the brain, rather than to abnormalities of the eye.
Christine Roman-Lantzy has done much research in the area of Cortical Visual Impairment. In her book, "Cortical Visual Impairment: An Approach to Assessment and Intervention", she identifies the cause of CVI can generally be thought of as conditions that affect the visual pathways or visual processing centers of the brain. It is a condition in which children have reduced visual acuity as a result of damage to posterior visual pathways. In most cases, the eyes of such children are structurally normal, yet they have diminished visual capacity. She indicates that the most common conditions associated with a diagnosis of CVI are asphyxia, perinatal hypoxic-ischemic encephalopathy, intraventricular hemorrhage, periventricular leukomalacia, cerebral vascular accident, central nervous system infection, structural abnormalities, and trauma.
She further states that the occipital lobes of the cerebral cortex at the back of the brain are primarily concerned with vision; the visual messages from the eye traveling along the optic nerve pathway in the form of electrical signals are routed to this location. The child may have an abnormal MRI or CAT scan that shows damage to parts of the brain such as the visual cortex or optic radiations. When attempting to determine the cause of a child’s visual disability, CVI should be considered when the child has:
A normal or near normal eye exam that cannot explain the child's impaired vision.
A history or presence of neurological problems.
The presence of behavioral responses to visual stimuli that are unique to CVI.
If you discover that the student has a history of seizures, be very cautious in using any flashing lights as this may trigger a seizure.
CVI is frequently seen in children who were born prematurely, have neurological disorders, or have acquired brain injury. When CVI is suspected, a review of medical and other records is needed. The presence of CVI is indicated when these three criteria are met. Dr. Roman-Lantzy has identified the following characteristics of CVI:
strong color preference, especially for red or yellow
need for movement to elicit or sustain visual attention; either the viewer or the object viewed needs to be moving to maximize the viewer's ability to view the object
visual latency - delayed responses in looking at objects
visual field preferences - the presence of unusual field locations in addition to loss of visual field.
difficulties with visual complexity - difficulty when an object itself presents a complex display when an object is viewed within an environment that presents a complex display, or when an object is viewed at the same time that other sensory input is competing for the viewer's attention and ability to manage sensory stimuli.
light-gazing and non-purposeful gaze
difficulty with distance viewing
absent or atypical visual reflexes - the reflex to blink in response to an approaching object is impaired
difficulty with visual novelty - a preference for viewing familiar objects is shown
absence of visually guided reach - the ability to look at and touch an object at the same time is not displayed, and these two actions are performed separately.
Overall, children who exhibit any of these characteristics or visual behaviors are usually unable to use their vision consistently in what might be thought of as a “normal” way. In general, the greater the severity of CVI, the greater the number of CVI characteristics present. However, these characteristics may change or improve. For more information on CVI and strategies from Christine Roman, visit the APH.
Additional CVI Resources...
Roman-Lantz, Christine. Cortical Visual Impairment: An Approach to Assessment and Intervention. American Foundation for the Blind, 2007. This resource book includes the unique assessment tool developed by Christine Roman-Lantzy and systematic, targeted principles to help students with cortical visual impairment. Includes a framework with which to understand working with CVI and concrete strategies in working with these students.
Roman-Lantz, Christine. Cortical Visual Impairment: An Approach to Assessment and Intervention, 2nd edition. American Foundation for the Blind, 2018. The new and revised content in this second edition brings the book up-to-date with new research and insights into CVI, its development and progression, and the best approaches to assessment and intervention with children affected by this condition. As in the previous edition, assessment forms, including the CVI Range and CVI Progress Chart, provide a comprehensive method for evaluating the functional vision status of, and program planning for, children with CVI.
The American Printing House for the Blind has a great CVI website with information on Cortical Visual Impairment. Information includes articles, videos, stories, as well as supports, strategies and resources.
The Texas School for the Blind has a comprehensive article on Cortical Visual Impairment that was featured in their See Hear Newsletter.
Little Bear Sees is a website dedicated to raising awareness about cortical visual impairments. It is designed to provide the information and tools necessary for helping children with CVI learn how to see.

Object Characteristic Activities
Quantity & Number Concepts
Time Concept Activities
Environment & Job Awareness Activities
Listening Skills Activities
Reading Foundation Activities
Reading Fluency Activities
Braille Basics Activities
Writing Activities
Tactual Efficiency Activities
Developing Skillful Hands Activities
Visual Efficiency Activities
Optical Device Instruction Activities
Recipe Activities
In addition to the core activity areas, each of the 32 Thematic Units incorporates additional unique ECC concepts and skills providing you with a years’ worth of activities. These units are cyclical and can be used repeatedly to help students build on prior knowledge and develop a deeper understanding of concepts.
