A diagnosis of Cortical Visual Impairment is typically made for children who display abnormal visual responses that cannot be credited to the eyes themselves. Cortical Visual Impairment is typically diagnosed when a medical professional carefully examine your child’s eyes.
An eye exam can show anomalies of your baby’s optic nerves such as paleness and large cups. Your child’s pupils may react normally during this examination. Your baby may show signs of an inability to fixate or follow stimulation—even when the stimulation is intense.
In addition to a thorough eye exam, doctors and specialists will measure your baby’s visual acuity. Their health care team will also assess your child’s visually guided responses, especially the way they reach and the way they scan their environment. Your son or daughter might also be referred to a pediatric low vision specialist for further evaluation.
