| Popis: | Normal anterior segments from five human eyes were prepared for scanning electron microscopy by fixation in glutaraldehyde and OsO4, careful dissection, drying and coating. The lens equatorial region, the zonules and the ciliary body were examined from behind and front. The zonules were found to insert at circular lines immediately in front of and behind the equator of the lens, and some directly on to the equator. In the ciliary body they inserted along the ridges of the processes. Their insertions by ramification are studied in detail. No zonules were found to insert into or pass through the ciliary valleys, nor did they insert on pars plana or ora serrata. Short zonule-like strands connected the posterior end of the processes with pars plana, and a mat consisting of confluent zonule-like fibers, running in a meridional direction, covered the surface of pars plana. The zonules inserting behind the lens equator seemed to adhere to the anterior face of the vitreous, but they did not merge into it. |
