As in a number of mammals, the most prominent feature of the ganglion-
cell layer in the retina of the murciano-granadina goat is an increase
in the density of ganglion cells in the central area, as well as a co
ncentration along a ridge extending horizontally across the retina, be
low the optic disc, and in the upper temporal retina. Thus, there is a
n area of maximum density and two streaks that are known as the 'horiz
ontal' and 'vertical' streak. The isodensity lines of ganglion-cell di
stribution is roughly concentric, with their values varying from 304 c
ells/mm(2) in the periphery to 3592 cells/mm(2) in the central area, w
ith the cells densely packed. There were some individual differences a
mongst the animal studied, although all of them were purebred animals.
