[Distribution of cone pedicle and superficial capillary. A morphological study on the macular region of normal human retina].
The distribution and arrangement of cone pedicle (CP) and peri-foveolar superficial capillary net works (SC) in the macular region was studied in two eyes obtained from a 24-year-old male and a 34-year-old female, light and electron microscopically. CP and SC were not seen in the central area of the macular region. Both the CP-free zone and SC-free area were ellipsoid in form and the horizontal dimensions were larger than 140 microns and 425 microns in one case and 360 microns and 630 microns in the other. The dimensions of the SC-free area measured 200 microns and 500 microns in the first case and 520 microns and 650 microns in the second. The para-foveolar circle formed by CP- and SC-free zones were concentric and the SC circle was about 50 microns larger in radius than that of CP.
