Welcome to our renewed website!

Cerebral Visual Impairment (commonly referred to as CVI) is a form of visual impairment caused by the brain not being able to process information from the eyes passing along the visual pathways in the brain. It is the commonest cause of visual impairment in children in the developed world.

If you know someone who has a diagnosis of cerebral visual impairment or if you or someone you know has difficulty with any of the following activities and there is no apparent reason why, then the CVI Society may be able to help you find out more information and to connect with other people who understand.

It is possible to have cerebral visual impairment and good clarity of vision, and many people with cerebral visual impairment do not have a significant problem with their eyes. This is one reason why they may often go undiagnosed. Advice may also be of use to adults who may have suffered a stroke or brain injury.

Have a look at the information we have here and if you have concerns then get in contact.

Through its Annual Meeting, its website, resources and social media, the CVI Society aims to raise awareness of CVI, and to help people of all ages who may be directly or indirectly affected.

During my professional career as a paediatric ophthalmologist, visual impairment due to brain injury or impaired function, became by far  the commonest cause of visual difficulties in children. 

It also occurred frequently in people suffering head injury, stroke or dementia, as well as in those with other causes. 

The resulting cerebral visual impairment is a hidden disability. Unlike cerebral palsy, it cannot be seen. Yet it can be disabling, frustrating and lead to social difficulties. 

It is obviously not possible to learn from what cannot be seen. How is it possible to return an unseen smile, or recognise someone whose face is unrecognisable, and so, easily socialise?

The many children with cerebral visual impairment whom I’ve had the privilege to diagnose and help, have often become good friends. No longer were they learning disabled, their learning was empowered by this new knowledge. No longer were some children labelled as autistic with ADHD. Instead the cause of their inability to engage and to concentrate was recognised as being cerebral visual impairment and catered for. 

No longer were these children criticised for not being able to find things or for being clumsy. They were praised for doing their level best.

Moreover, the recent recognition that through training and endeavour, adults and older children with cerebral visual impairment can learn to make better use of their vision, can change lives for the better.
