There is cause for more than strong suspicion of the facts of the 
mammalian optical
pathways. The pioneer investigators demonstrated front end processing of the
 visual inputs providing paths  for angle and motion sensing for 
example - this cuts down on the bandwidth needed for image processing;  
and reduces  the impact of the slow transmission
speed of the neurones.
