Visual perception and processing describes the way we see, interpret 
and make sense of visual information and can be significantly impaired following Acquired Brain Injury. These skills are underpinned by visual acuity, intact field of vision and the ability to control the muscles of the eyes (oculomotor skills). Any assessment of visual processing and perception will need to take account of these other factors which may influence the quantity and quality of visual information relayed to the responsible areas of the brain.
Problems of visual perception and processing may often go unrecognised by the person with brain injury, their family, carers and by health professionals. Frequently, the person with these impairments may misattribute perceptual and processing impairments to changes in eyesight. It may be very difficult for the person to communicate such changes. They may also lack awareness of the problem due to cognitive difficulties, specifically executive functioning. Therefore, the person and their carers may lack understanding of why the person is unable to carry out a range of everyday activities.
Visual perceptual and processing skills are important for activities of daily living affecting routine tasks such as walking, dressing, reading, driving, cooking, eating and drinking. Impairment may also have a significant impact upon social, occupational and educational activities. This may result in the person increasingly avoiding participation in many activities (including social activities), significantly affecting their quality of life.
