Conditions

low vision, visual impairment, cerebral visual impairment (CVI)

Interventions

In the second stage of the project, children receive a visual training of viewing strategies (six weeks, 2 times a week, 30 minutes). During the training, children are instructed to use specific viewi

in a structured direction which fits the task at hand, zooming in and out / change of visual selective attentional field, visual discrimination). The verbal instructions and exercises are protocol bas

Eligibility
