2. results in the context of brain based visual impairmentUnderstand the FVA for the student with CVIUnderstand brain plasticity. Understand the expectation of visual improvement if opportunities are embedded in the day.Understand the issues around literacy for print use vs. picture understanding.Consider prevalence of auditory processing disorders in students with CVI.
3. Brain PathwaysStudent might have built stronger auditory and tactile pathways but visual pathways are available if provided with accessible materials.Recommendations for vision based media must be based on individual need.Age of the studentOver-preference on hearing or visionLack of visual opportunity: media not accessible without supportNeed to provide visual opportunities
4. Reading Media at NearEvaluation of the child’s reading and writing skills must be looked at in the context of CVIIncreased print size is not due to acuity but to crowding.Need for flexible print Print needs are based more on visual complexity, spacing, visual field neglect and number of items on the page.Pictures are more inaccessible than print.
5. Reading at NearReading speed might be impacted by novelty.Reading speed might be impacted positively by backlighting.Reading might be impacted by noise of the testing area.Understanding of worksheet might be based on picture/symbol inaccessibility not print understanding. (Tietjen “What’s the Complexity Assessment”)

9. Communication DevicesStudent with CVI are impacted by:Complexity (visual and auditory)NoveltyIncreased arraysColor codingDifficulty with highly symbolic images
10. Access to distance mediaInaccessible due to the CVI visual characteristics of complexity (visual, auditory), novelty, and distance.
11. Writing AssessmentImpacted by visual motor characteristic and complexity issues of CVISupported by color Supported by backlightingKeyboarding might be impacted by complexity and supported by color coding the keys.(image of writing “Jack” on a page with and without a color highlighted text box. In the text box is more readable)
12. TechnologyImpacted positively by backlightingSkills impacted by CVI issues of complexity and novelty.
13. Recommendations of accessMust also account for complexity of the environmentPrimary might be tactual but vision needs embeddingSecondary might be auditory but vision needs embedding (Must also account for visual fatigue and use auditory in visual breaks)Dual media is optimal, each at its level with thoughtful use to support building visual skills..
14. Using the LMAMust base LMA assessment in consideration of CVI characteristicsMust complete LMA in optimal environments and in non-optimal environmentsMust base recommendations on the expectation of vision improvement supported by compensatory skills.LMA recommendations must consider the whole child
15. FVA for CVI LMA in consideration of CVIDetermination of media based on visual improvements and compensatory skills for individual students.
16. Students with CVI: Dual Media LearnersPrimary learning sense considers access today.Visual improvement capacity is always considered.
