Cortical blindness: binocular field testing and MRI

(A) Binocular field testing demonstrated severe constriction, with a spared central area resembling a “keyhole.” The area of spared central vision in the right hemifield was slightly larger than the area of spared central vision in the left hemifield. (B) The MRI demonstrated chronic infarctions of both occipital lobes, with sparing of the occipital poles (Contributed by Dr. Sashank Prasad.)
