´ Awareness of the most common visual diagnosis associated with cCMV ´ General understanding of CVI and its characteristics ´ What to look for before a referral ´ Activities and Strategies for Adapting the Environment
u Light gazing/non-purposeful gaze u Distance Viewing u Visual Reflexive Response u Visual Novelty u Visual Motor
´ A classic characteristic of CVI is that a child might glance at something like a toy, look away, then reach for the object. ´ The environment and physiological factors may affect the child’s visual
illness, stress level, new surroundings, amount of light in the room, excitement, etc. ´ Need more processing time; wait time (delayed response when looking) ´ Preference for toys of a specific color, that light up or move ´ Stare at light or sun coming through windows
´ Not always easy to diagnose ´ Don’t wait for a diagnosis to implement intervention ´ Early diagnosis and intervention is critical because of neuroplasticity ´ Parents are often the best observers/reporters ´ Visual efficacy varies according to environment, health, sleep
´ Check blink reflex ´ Eye contact ´ Response to light – Stare/fixating or light sensitive
´ Decide which sensory channel you want the child to focus on and be careful not to overload with too much stuff. ´ Watch for the child’s interest level but be careful of the novelty
new. ´ Be consistent with the same colors, toys, placement of materials, how you speak to the child, etc. Then slowly change the item, by pairing the familiar with the unfamiliar. Make sure the new item has some similar characteristics. ´ Use a quiet environment with minimal distractions ´ Be aware of what you are wearing, clothing, makeup, nails, jewelry, hair/hair ties, perfume
´ Environment is KEY for work, play and eating… ´ Use black invisboards, black sheets, or solid dark curtains to block out the clutter.
´ Environment is KEY for work, play and eating… ´ Use a tray from APH , cookie sheet, or shallow bin to provide boundaries
´ Environment is KEY for work, play and eating… ´ Use simple, high contrast toys/materials
´ Environment is KEY for work, play and eating… ´ Glare: position away from windows,
´ Reflective paper has light and movement qualities that will attract visual attention
´ Environment is KEY for work, play and eating… ´Positioning should be supportive and not too physically challenging
´ Print materials-
´ Books should try to have single clear pictures with minimal detail. ´ Good contrast
´ Print Materials ´ Tactual Materials ´ Texture Books
´ Object Books
´ Homemade Books

´ Check 3 things and refer ´ 10 most common characteristics of CVI ´ How to set up the environment for fun (and visual success)!
´ There are various levels of CVI that will be reflected in in score
´ Even kids that are generally resolved (Score of 9-10) – may have residual effects that will continue to need to be monitored as they need to learn more complex visual skills
