  1. Becoming a Team to Build Understanding of CVI Burju Sari, M.Ed., CTVI Ellen Cadigan Mazel, M.Ed., CTVI Omer Sari, RCK

  2. *Omer’s Birth History • 31 weeks of gestational age • 6 weeks of NICU stay • First ultrasound showed brain bleeding • Second ultrasound showed that bleeding stopped • At 1 month- IVH- stage III-IV

  3. *Visual History • Not looking at faces • Slow visual processing • Down gazing • Frequent naps (rests) • Gazing at lights • Diagnoses of strabismus and prescription glasses

  4. *“I know something is wrong” • Video of “#1 Crib Complexity” • Video of stroller: “#2 Twins”

  5. *Misdiagnosis • Autism (EI) • Cognitively impaired (Infant-toddler follow up)

  6. *Perkins Infant Toddler • At 6 months- Ellen’s first visit for FVA • CVI training • Infant toddler group on campus & parent group • Support • Sharing experience • Learning more

  7. Omer’s visual skills: 6 MonthsScore 1-1.25 • Color: Looking at red, solid colored items. Locating red faster and sustaining longer • Movement: Like shiny things. Movement gains a brief look. If items don’t move, he doesn’t glance at all. Hates places with many people moving around. • Latency: Difficult to gain visual attention. Brief when it occurs.

  8. Omer’s visual skills • Visual field: Left visual field is stronger. Looks down to the left. • Light: Consistent lightgazing. • Visual novelty: Limited number of items are visually regarded • Complexity/Latency: Napping or “playing possum”.

  9. Video: “#3 Lights”

  10. Omer’s visual skills • Complexity: Fussy in busy places. • Complexity: Only quick glances towards faces. Looks quickly away when voice is introduced. • Visual Motor: Less movement of hands. • Visual Reflexes: No blink to touch or visual threat.

  11. Adaptations: Color: • Use red as highlighting color • Feeding: bottle and spoon are color highlighted Movement: • Reduce access to distracting environmental movement • Use movement to draw visual attention

  12. Adaptations: Latency: • Slow down and give him time to locate items Visual Fields: • Present items in peripheral, left visual field. • Present familiar, lighted and moving items in weaker right visual field.

  13. *Adaptations: Complexity • Use single colored items • Use books with storyboxes • Provide plain backgrounds • Reduce other sensory inputs (sounds, touch, vibration) while looking • Provide multisensory learning with one sense challenged at a time.

  14. *Adaptations: Lightgazing • Eliminate distracting light sources • Use light to draw visual attention to meaningful items Distance • Provide consistent items at 12”-18” to play with. • Narrate distance events.

  15. Adaptations: Novelty • Standardized presentations • Familiar toys • Familiar routines Visual Motor • Active learning

  16. Reaching: Video: “#4 No VM” • Video “#5 VM to sound”

  17. Improvements 9 months: Score 3.75-4 • Looks at mom (important for a mom) • Expanded his toy selections • Breaks away from light sources to look at toys • Looks at more novel materials is they match color, light, shape. • Red still favorite but expanding color interest.

  18. Improvements 9 months: Score 3.75-4 • More visual interest and visual curiosity • Looking at 2-3 feet if something is moving. • More social • More reaching to items in his environment: Very dependent on sound • More visual stamina.

  19. Omer: age 3 • Looks at all colors and multicolored items. • Sustains gaze on materials • Looks at faces but “look through you” quality. Very social. Smiles at everyone. • Only looks at light if he is tiring to walk in his walker • Looks at stable items around him at 3-4 feet. • Looks at distance movements.

  20. Clearly on Task Cognitively • Video “#6 ABC”

  21. Omer: age 3 • Likes to look at books • Looks immediately on presentation of materials • Blink reflex present • Can look at noisy toys.

  22. Video “#7 Complex sticks”. • Video “#8 sticks black” • Video “#9 walking outside”

  23. Scoring wrong: Age 3Scoring Too High • Looking is not understanding • Using CVI Range statements as the only basis for understanding CVI • Characteristic can disappear from the CVI Range statements but that visual characteristic still impacts learning. • Visual characteristics all remain important for visual understanding and function.

  24. Thinking Characteristics are Resolved • Looks at all colors and multicolored items. • Looks quickly • Looks at faces • Looks at distance at times

  25. “I see the impact of his CVI everyday” Color: Still Important • He asks for red clothes. • He has a red bike. • Playing a board game he automatically picks red color side of the game or symbol.

  26. Color: Still Important • He picked red glasses frames. • Going to a party or somewhere busy, he asks mom to wear red or orange. • Likes other colors too like blue. • Brother in red bumper cars. • Picked Mario as a Halloween costume with lots of red and blue.

  27. Color: Still Important

  28. *Movement: Still an Issue • Movement helps location against complexity • Movement helps him find things at distance • Movement distracts him in peripheral visual fields.

  29. Latency: Still an Issue How we know • Visual fatigue • Longer time to find against complexity • Longer time with novel items • Longer time at distance • Longer time for facial recognition.

  30. *Transition to School Reasons for collaboration: • IEP: nonsense words (Police car) • Classroom teacher taking classes: preschool • Needed services

  31. *Misconceptions about high Phase II and III • Social emotional challenges • Cognitive impairment • Cognitively fatigued • Distractible

  32. *What is left over now? ”I see the impact of CVI everyday.” • Color supports understanding: Likes and picks “red” color • Latency: Visual fatigue and for understanding new things • Complexity: Just realized our dog has a face

  33. *What is left over now? • Novelty: His brother’s bike is different • Novelty, Complexity: Cutting nails • Distance viewing: Can’t see the kite • Complexity: Facial recognition is still difficult

  34. Video “#10 Complexity Cheerios • Video “#11 Not looking crowd”

  35. *What happens in new places • Gets quiet • Gets fatigue easily • Head down • Hates field trips • Difficulty recognizing people from different nations

  36. The more you learn about CVI the harder it is to explain.

  37. *Self Advocacy Understanding His CVI • (Video: Omer explaining his own CVI)

  38. *Self Advocacy: Building his advocacy skills: • Less complex/busy • Ask to be closer to targets • Description of distance events/situation • Frequent breaks

  39. What expanded learning for team around CVI? • Matt Tietjen’s “What’s the Complexity” framework • CVI Scotland website • Perkins CVI Hub • Perkins Elearning • Christine Roman Lantzy: Cortical Visual Impairment: An Approach to Assessment and Interventions 2018 • Dr. Gordon Dutton: Vision and the Brain
