There are 17,500 conesdegree Rod free area is approximately 10 thus there are 17,500 cones in the central rod-free fovea. Total number of cones in the retina. - 6,400,000 Total number of rods in the retina. - 110,000,000 to 125,000,000 Rod distribution. Rods peak in density 180 or 5mm out from the center of the fovea in a ring around the fovea at 160,000 rodsmm2 No rods in central 200 pm. Average 80-100,000 rodsmm2 Rod acuity peak is at 5.20 or 1.5 mm from foveal center where there are 100,000 rodsmm2
