    • Introduction to Case Studies

      In this video, you are invited to participate in the assessment of each student.  You will need to use a data collect sheet (one is included on this website for your convenience) as well as blank copies of the assessment from Christine Roman-Lantzy’s Cortical Visual Impairment: An Approach to Assessment and Intervention.  You will use these documents for information as well as to write down your notes as you follow along in the assessment of each student.

    • Brandon (Phase 1)

      In this video, you are introduced to Brandon.

      • Brandon Interview 

        Lynne and Sara analyze the information from the completed parent interview and transfer it to Brandon’s data collection sheet.

      • Brandon Observation

        Lynne and Sara analyze the videos of Brandon’s everyday routines, as well as some environments we slightly modified to give more information about his vision.  We observed him in his living quarters, in his classroom, and walking in a quiet hallway.  We noticed that Brandon is extremely distracted by (and loves) social interaction. As the video is reviewed, data gleaned from it is recorded on the data collection sheet.

      • Brandon Direct Assessment

        Lynne and Sara analyze video from three different direct assessment sessions.  During each assessment session, the environment required a great deal of modification in order to elicit visual responses.  Information gathered from the direct assessment is recorded on Brandon’s data collection sheet.

      • Brandon Finding the CVI Range

        Lynne and Sara transfer the information on the data collection sheet to the CVI Range.  The Rating 1 Scoring guide was used to help synthesize the data and help complete Rating 1.  Rating 2 was was completed as well to find the CVI Range.

      • Brandon Filling Out the CVI Resolution Chart

        The CVI Resolution Chart can be a quick reference guide to use when developing the IEP to accommodate and support a student's current visual functioning.  Using Rating 2 for reference, the CVI Resolution Chart was filled out following the directions given on the bottom of the chart.

      • Brandon Present Level of Visual Functioning and Adaptations

        The Ratings in the CVI Range have uses that may be important to teachers of the visually impaired or others who are considering CVI assessment results and how they affect educational programming. Rating I can be used to determine present levels of visual functioning and Rating II can be used to determine modifications or adaptations for the Individual Education Plan. These two sets of information are important when writing a functional vision evaluation and learning media assessment, and can make up the bulk of the CVI narrative, if done separately.  In this video, Lynne and Sara show how that information can be used for planning Brandon’s IEP.

    • Cassie (Phase 2)

      In this video, you are introduced to Cassie.

      • Cassie  Interview

        Lynne and Sara analyze the information from the completed parent interview and transfer it to Cassie’s data collection sheet.

      • Cassie Observation

        Lynne and Sara analyze the videos of Cassie’s everyday routines, as well as some free play.  We observed Cassie indoors in her classroom, walking outside, and in the cafeteria.  Cassie enjoyed physically manipulating objects in her environment to make things happen.  She was also able to communicate several types of requests to adults using verbal approximations and gained attention using touch or her voice.  As the video is reviewed, data gleaned from it is recorded on the data collection sheet.

      • Cassie Direct Assessment

        Lynne and Sara analyze video taken during one direct assessment session. Cassie was taken from the active classroom to a setting with less competing environmental and visual complexity than the classroom.  Information gathered from the direct assessment is recorded on Cassie’s data collection sheet.

      • Cassie Finding the CVI Range

        Lynne and Sara transfer the information on the data collection sheet to the CVI Range.  The Rating I Scoring guide was used to help synthesize the data and help complete Rating I.  Rating II was was completed as well to find the CVI Range.

    • Ian (Phase 3)

      In this video, you are introduced to Ian.

      • Ian Interview

        Lynne and Sara analyze the information from the completed parent interview and transfer it to Ian’s data collection sheet.

      • Ian Observation

        Lynne and Sara analyze the videos of Ian’s trip to a local grocery store.  We observed him walking outside, in the van, and in the store.  Ian maneuvers through various sections of the store and then makes a purchase. As the video is reviewed, data gleaned from it is recorded on the data collection sheet.

      • Ian Direct Assessment

        Lynne and Sara analyze video from several different environments over the course of two testing sessions. Ian was taken from the active classroom to a setting with less competing environmental and visual complexity than the classroom.  Information gathered from the direct assessment is recorded on Ian’s data collection sheet.

      • Ian Finding the CVI Range

        Lynne and Sara transfer the information on the data collection sheet to the CVI Range.  The Rating I Scoring guide was used to help synthesize the data and help complete Rating I.  Rating II was was completed as well to find the CVI Range.

      • Ian Filling Out the CVI Resolution Chart

        The CVI Resolution Chart can be a quick reference guide to use when developing the IEP to accommodate and support a student's current visual functioning.  Using Rating II for reference, the CVI Resolution Chart was filled out following the directions given on the bottom of the chart.
