Exactly. There is little if any two-way optic nerve flow in
human beings. Neuroanatomists and neurophysiologists have been
looking a long time and haven't found it. The situation is
different for lower vertebrates.

Functions like focus and pupil size do not involve the optic
nerve but sympathetic and parasympathetic pathways traveling
through smaller nerves (e.g. ciliary nerve). They have little or
nothing to do with higher order visual perception.

Eye muscle movements involve still other nerves, like the brain
stem's oculomotor nerve and trochlear nerve. Eye movements can
be reflexive (e.g., maintaining fixation, tracking movements) or
directed from above (e.g. reading). Maintaining stability of the
scene is an important function, since every time we move our
eyes, the image sweeps across our retinas. How does the brain
"know" whether the movement is caused by actual movement or eye
movement? There is a clever system called outflow, where the
cortical centers controlling the voluntary movements signal the
brain centers interpreting movement. The outflow signal to move
the eyes is used to cancel information coming up the optic nerve
to the cortical vision centers that the image is moving on the
retina. Thus the world does not seem to move even though our
eyes are darting around. It's a good thing the oculomotor
centers are able to tell the motion centers they are moving the
eyeballs, because otherwise the motion centers would be
constantly misinterpreting retinal motion as actual motion and
our visual world would be chaotic. (There are rare unfortunates
afflicted with this condition.)

There was a long debate over the outflow theory. Others held
that there must be two-way sensory information from the eye
muscles themselves traveling backward along the oculomotor
nerves telling the brain where the eyeball was (as is the case
with most of our muscles, telling us where our various body
parts are positioned). But this turned out not to be the case.

It is very simple to demonstrate the outflow system at work.
Press on your eyeball to move the eye and the whole outside
world seems to move. I leave it to the nihilists to conclude
this demonstrates that no perception can ever be trusted. To me,
it is only a demonstration that the perceptual system can be
deliberately fooled through manipulation, to deprive it of the
information it needs to come to the right conclusion. And even
though the world seems to visually move, things still do not
seem right to our brain, because other perceptions conclude that
our bodies are not moving along with the moving world. So its
not exactly a case of being totally fooled.

Two way pathways of varying reciprocity are ubiquitous between
brain areas. One of the more likely reasons for these two-way
connections is so that the brain can cross-correlate the
information derived from the various areas. This is not a case
of one area telling the other what to "believe", but the brain
working as a unified whole, one reason perceptions tend to be
self-consistent and stable. Thus we often know we are having a
visual illusion probably because the perceptual conclusion of
one brain area conflicts with the conclusions of other areas and
whatever is monitoring the output of these various areas
(consciousness?) notes the conflict.

To badly paraphrase Abraham Lincoln, you can fool some of the
brain areas some of the time, but you can't fool all of the
brain areas all of the time (unless something pathological is at
