What are the symptoms of cortical blindness?

Inability to see. Cortical blindness is loss of acuity due to damage to the occipital lobe of the brain. This can be a birth defect or an acquired vascular defect. If at birth, the child will show no recognition of the space around him, the eyes usually will dance (nystagmus) and will not track together. As an adult, the eyes cannot fixate, the pupils usually react to light but no vision will be reported.
