WHAT IS CORTICAL VISUAL IMPAIRMENT?
Cortical visual impairment (CVI) is an impairment in which the brain is unable to process signals from the eyes.
It’s usually caused by brain damage or injury.
Many people with CVI can only interpret simple and familiar images, moving objects and certain colours. They may also have delayed or improper responses to images.
CVI can improve with proper intervention. Unfortunately, CVI often goes undiagnosed because the eye might appear perfectly normal during an eye exam.
It is believed to be very common in children with cerebral palsy.
