Classroom Tools

CVI Book Builder

The CVI Book Builder was created for children with Cortical/Cerebral Visual Impairment (CVI). The kit makes it easy to create meaningful books that provide a foundation for literacy for young learners.

Because children with CVI often have difficulty in understanding objects, pictures, and letters presented against a complex background the CVI Book Builder takes a different approach. In the kit you’ll find black pages and black binders that serve as low complexity backgrounds where you can present familiar items, photos, and eventually words. The CVI Book Builder manual guides parents and teachers in creating individualized books specifically for their reader with CVI.


CVI Complexity Sequence Kit

APH’s CVI Complexity Sequences Kit includes cards that present sequences of images designed to refine the ability to identify a target in the presence of increasing amounts of background information. These cards may be used individually or as a sequence and should be presented against a black or plain, light-absorbing background.


Increasing Complexity CVI Pegboard

Paired with diagnostic teaching strategies, the Increasing Complexity CVI Pegboard set helps create low to high complexity background templates against which to present peg activities. These activities help determine and support a child’s color, lighting, movement, and complexity needs.

When paired with the Light Box, this board can be lit up to guide the learner. Add a colored Light Box overlay under the pegboard to provide a light color cue. The Invisiboard can help block out distractions and the All-in-One Board can be used when light is no longer necessary to elicit attention.

LED Light Box

Recommended for all ages, APH’s LED Light Box and accompanying materials help utilize students’ residual vision to track, scan, and develop eye-hand coordination, visual discrimination, and visual perceptual skills.

LED Mini-Lite Box with Stand

Now featuring an energy-efficient LED light panel and a rechargeable lithium battery pack! The LED Mini-Lite Box is an all-inclusive person-centered learning tool for students who are visually impaired. Students with CVI and other disabilities can benefit from the Light Box Materials kits and commercially available mounts that can be attached to the LED Mini.

Babies with CVI: Nurturing Visual Abilities and Development in Early Childhood
Babies with CVI: Nurturing Visual Abilities and Development in Early Childhood is a guide through the history and best practices related to the treatment of CVI in children from birth to 36 months. Author, Anne McComiskey, maintains that the vision of children with CVI can be most effectively improved when interventions are started as early as possible. There are, unfortunately, obstacles in implementing early interventions. This important book offers guidance to teachers of children with visual impairments as well as to families to ensure that babies with CVI receive appropriate interventions as early as possible. The anticipated release date of Babies with CVI is Summer 2021.

CVI: An Approach to Assessment and Intervention

CVI: An Approach to Assessment and Intervention provides educators, therapists, physicians, and parents of children with CVI with an understanding of the condition and a complete framework for assessment and intervention.


Vision and the Brain

Vision and the Brain provides current research and thinking on CVI including: the role of the brain in vision; effects of brain damage on vision; impact of CVI on child development; consideration in behavioral diagnosis; CVI, autism spectrum disorders, and ADHD; eye movement disorders in children with CVI; and refractive errors and impaired focusing.
