Cortical Visual Impairment (CVI) is diagnosed when children show abnormal visual responses that aren’t caused by the eyes themselves. When CVI is suspected, fixation and following—even to intense stimulation—may be poor, and the child will not respond normally to people's faces.
- CVI is the most common cause of permanent visual impairment in children.
- Accompanying features of CVI include cerebral palsy and developmental delays.
- In many cases, partial recovery of vision is possible.
