ABSTRACT
The commonest cause of impaired vision in children, in developed economies, is brain injury or dysfunction arising before, during or after birth. The brain creates a mental emulation of the seen environment that matches the physical attributes of the surroundings. If disordered, a unique pattern of atypical vision becomes the norm for the affected child.
Children learn only from what they see, hear and understand. To be successful, all teaching must be accessible, so every child with cerebral visual impairment (CVI) must have known profiles of their vision, their prior knowledge and their current abilities, which are always used to best advantage.
