Overlooking Children in Phase II and Phase III (Roman-Lantzy)

I hear too often that a child can’t have CVI because they can look and reach or can move through the environment. This is incorrect. Children in Phase I are very visually impaired and appear blind. It is easy to understand their visual impairment even for untrained people. Children in Phase II and Phase III, have some visual abilities. The untrained person sees these visual behaviors and mistakenly believes the child can use their vision effectively to learn. It is essential to have an assessment using the CVI Range (Roman-Lantzy 2007) before deciding whether a child has CVI or not. It is only through rigorous assessment around the 10 characteristics that we can determine a child’s functional vision. It is always the children in Phase II and Phase III that are overlooked and under-assessed. Children in Phase II and Phase III sometimes reach, track and move around well but struggle with visual recognition. This lack of visual recognition is the major roadblock to learning. The lower field is often still a problem well into Phase III. Facial recognition is often strongly effected well into Phase III. Children should certainly see an ophthalmologist to rule out any ocular issue but a trained TVI who understands CVI and how to use the CVI Range must do a functional vision assessment using the CVI Range before dismissing CVI. It is the functional visual assessment to identify visual skills in need of support so learning is optimal.
