Figure: Eye anatomy for (a) mamals and (b) birds.

(Adapted from:

The figure (a) depicts a tipical mamalian eye (it is from a dog). On figure (b) one can see an avian eye (from a chicken). They were represented on differing scales in order to show them as they would have the same size at the vertical diameter. At first we can poit the following differences between them:

This last property makes the chicken retina a very interesting experimental substract. One can observe transport phenomena across the retina without being disturbed by the network of blood circulation.


The structure shown at the left is the so called pecten.
