Hello Kristie and thank you for your questions. Here are my thoughts: 1) Children with CVI (cortical) have a history of functional and/or structural differences. The MRI is not conclusive regarding CVI…in fact, there is no definitive way to look at the brain and predict the presence or absence of CVI. So, I guess I am wondering what you mean by “evidence”. That can be interpreted in a number of important ways. 2) TVIs or COMS do not and should not diagnose CVI. However, if they conduct an appropriate assessment and find that the child’s functional vision “adversely affects educational performance”, interventions can be put in place even without the formal diagnosis. 3)Regression in functional vision is not usual-if you see this, I suggest the team carefully review factors such as the accuracy with which The CVI Range was conducted, the match of the CVI Range score to the environmental supports and educational materials/methods, and the frequency with which the individual with CVI is able to use vision effectively across the routines of the day (CVI Schedule). These are the procedures I have found most useful.
