Cortical Visual Impairment by Anthony Kuechle https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o Helpful tips for new teachers en-us 2021-01-31 19:56:14 UTC 2021-02-02 05:16:06 UTC hello@padlet.com Statistics anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146194036 -Approximately 30-40% of children with visual impairments have CVI
-10.5% of children with developmental disabilities will also have CVI]]> 2021-01-31 20:00:13 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146194036 anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146236438 Student is just starting to use their vision. They often alert to light, single brightly colored objects, slow moving targets and bright walls. Environmental and sensory compete against each other when the student it trying to see. The visual target needs to be close, within arm's reach and usually the student needs the viewing array limited to one or two widely spaced targets only. Students often need high contrast between a single target and its background. They see things best when its presented at their far left or far right eye height. Lower visual field is poor. Student prefers familiar targets. Visual fatigue is often a problem with eye/hand use.]]> 2021-01-31 20:24:29 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146236438 anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146239770 Students generally use their vision more consistently, but often not efficiently or for a purpose. Contrast between target and background for the student continues to be important. Student can tolerate more patterns that are near. Attend more frequently when targets are presented not only at far right and far left, but also centrally. Lighting continues to draw students visual attention and can often be used to encourage interaction with objects for functional purposes.

Students using Strategies at Level 3 will be responding to more varied visual targets and have greater visual demands.  Be careful to watch for visual fatigue and allow plenty of response time, to look at the visual target then respond to it.
Student often demonstrates more typical visual behavior, but may continue to have difficulty with competing environmental and sensory input while trying to use vision, especially when viewing targets at distance.  They may continue to have visual field preferences and often have difficulty viewing targets when presented in their lower visual field.]]> 2021-01-31 20:28:17 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146242284 Strategies for Level 1 anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146243480 2021-01-31 20:28:59 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146243480 Strategies for Level 2 anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146243900 2021-01-31 20:29:17 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146243900 Strategies for Level 3 anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146244089 2021-01-31 20:29:23 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146244089 anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146247058 Repetition, repetition, repetition! 
Use the same objects and the same process each time to provide familiarity, reduce latency period, and shorten warm up time, having the same individuals working with the student in the same way again and again is often helpful! ]]> 2021-01-31 20:31:17 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146247058 anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146253524 Since students using Level 2 Strategies now are using their vision for more functional purposes, it will be important to look closely at the student’s daily routines, both at home and at school, to determine appropriate accommodations.

Verbally note salient features when discussing visual targets (“The ball is yellow and round”).

Be careful with, or avoid use of, pictures.  Generally, a student who benefits from Level 2 strategies needs real, tangible targets (3D).  Switching to 2D targets or pictures is often difficult.  Color photographs of familiar, favored targets often work best during this process.

Providing a routine and structure/sameness continues to be important.

Observe student carefully to make sure the presentation of visual targets is not too fast; allow the student time to process what is being seen and to respond to what is being presented

It differs to visual impairment related to physical problems with the eyes. Students with CVI are able to see, but the brain is not interpreting what is being seen. ]]> 2021-01-31 20:51:25 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146278562 Characteristics (10) anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146284064 1.

Most children start in Phase I, which means that most of the CVI characteristics are present. As a child progresses through the three phases many of the characteristics begin to resolve. This process can take several years and requires diligence and persistence. Children in Phase III approach near normal vision to varying degrees and this may even result in literacy.]]> 2021-01-31 20:58:30 UTC https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146289406 References: anthonykuechle1 https://padlet.com/anthonykuechle1/yk86wghxfo0oet1o/wish/1146291452 https://strategytosee.com/strategies-for-students-with-cortical-visual-impairment-handout/

Be careful to watch for visual fatigue and allow plenty of response time. Allow them to look at the visual target and then respond to it.
Be specific about what you want the student to look at.
Good communication at school and at home is crucial.
Continue to monitor pictures for visual clutter and use pictures that the student can identify.
It's critical that all teachers, caretakers and parents follow the same teaching procedures at school and at home. Example: If a yellow highlighter is used to mark at school, then the same highlighter should be used at home.
