nerve structure of eye?

[Claudius Schnoerr]

Hello, 

can someone direct me to some literature about the nerve structure of
the eye of higher animals (cat, monkey, human)?

I'd like to know how many photoreceptors an eye has, their density
distributions and the number of nerve connections with the brain.

Please e-mail to

Many thanks
