In brief: A few
Cortical blindness is due to failure of the occipital lobe, the visual information processing center of the brain, to function properly.
Many of these occur at birth. The eyes frequently are normal with normal pupillary reaction, yet the patient reports not seeing anything. There are tests of cortical electrical activity (vep) similar to an eeg which can register the lack of activity.
