Cortical/cerebral visual impairment (CVI) is the leading cause of visual impairment in children in the US, but many people have never heard of it. CVI is a brain based visual impairment, where the problem is with the brain, not the eye. With this condition, children see exactly what we see but their brain is unsure of how to interpret it. The good news is that with early detection and intervention the functional vision of the child can be improved.
CVI is caused by an injury to the brain. This injury can occur before, during, or shortly after birth. Common causes of CVI include:

Some kids with CVI tend to stare at light, while others are light sensitive.
Cortical/cerebral visual impairment can not be diagnosed by a single test, so it is important that your child receives a comprehensive eye exam. Children should have their first eye exam at 6 months of age, followed by another exam at 3 years, and again before they start school. Early detection is key and this schedule is the best way to make sure your child’s vision is problem-free.
There is no cure for CVI but vision therapy can help people with CVI make the most of their vision.

Our Pediatric Optometrists are here to educate and provide solutions for a wide range of visual issues that can occur in children. They can test for color vision deficiency, depth perception, visual acuity, and the health of your child’s eyes.
