What if your student has a visual impairment - CVI?


Cortical Visual Impairment is sometimes also called Cerebral or Neurological Vision Impairment or CVI.  

CVI is recognised as being the most common cause of visual impairment in children, especially in children who have PMLD.

CVI is a temporary or permanent visual impairment caused by damage to the brain (Dutton & Bax, 2010.) It is different from other forms of visual impairment in that the interference in visual function does not typically happen in the eye or optic nerve, but in the visual processing centres or visual pathways of the brain.

Students who have a CVI can also have other co-existing eye conditions. 

The impacts of a CVI can range from mild to severe. 


Most children with CVI have other associated neurological problems. The most common of these include cerebral palsy, epilepsy, hydrocephalus and/or learning difficulties.



CVI is not an eye condition it is a BRAIN condition
