This is an interesting condition as neither a CAT scan nor a VEP can confirm the condition. Treatment is usually effective for cortical blindness and a series of vision stimulation activities can be performed to increase the field of vision. Children are more likely to recover from the symptoms than adults, some theorize that this is because the fibers of the optic tract may be important for the visual recovery. It has been known for adults to recover too.
The anterior visual pathway refers to the pathway that visual information takes from the eyes to the visual cortex in the brain. It includes the optic nerves, optic chiasm, optic tracts, and lateral geniculate nucleus. This pathway is responsible for transmitting visual signals from the retina to the brain for processing and interpretation.

The temporal occipital lobe is the cortical area involved in auditioning. It is the visual processing center of the mammalian brain.

There is no visual pathway to (or from) the hands. This idea says objects near the hands are immediate candidates for action. It doesn't mention in any way that there is a visual pathway from the hands to the eyes.Just means that you are more likely to use something nearby your hands (in sight) than some that are not (in sight).This has "led us to hypothesize that vision near the hands would be biased toward the action-oriented magnocellular visual pathway that supports processing with high temporal resolution but low spatial resolution". ~From a published scientific article.

it is partial blindness that may result in blindness in the same visual field of both eyes
Moderate cortical changes. Wedge-shaped (cuneiform) or spoke-like (wheel) peripheral changes are seen. These changes may be extensive but may not affect Snellen visual acuity since they occur in the periphery.
