The number and distribution of the retinal ganglion cells in the 2 years old Korean native cattle was determined from whole flat mounted preparation stained with methylene blue and thionin. The total number of retinal ganglion cells was estimated to be 3,085,200 in the bovine retina ranging from 2.214mm** (2) in total area. Visual streak was recognized at the area 2.5mm superior to the optic disc and ganglion cell density drops off rapidly to the direction superior to and inferior to the visual streak. Area centralis (6,800 cells/mm** (2)) was located at the area 10mm temporally from the point of 3mm superior to the optic disc. The number of alpha-type ganglion cells (above 15 micro) was 57,000 in the bovine retina and alpha-type ganglion cells constituted 18.5 % of the total cells. The relative frequency of alpha-type ganglion cells was higher in the peripheral regions than in the visual streak, especially higher in the superior-temporal quadrant than in other region of the bovine retina.
