All the dopaminergic cells were identified by their tyrosine hydroxylase immunoreactivity in whole-mounted retinas of two strains of albino rats. In Sprague-Dawley rats as well as in Wistar rats, a higher density of cells was observed in the upper temporal quadrant of the retina. The total number of dopaminergic cells was higher in the Wistar strain. Although a general increase could be noticed all over the retina, the maximum increase was observed in the upper temporal quadrant which can be considered as the central retina in rats.
