The development of the ciliary body was examined by scanning electron microscopy in human embryos and fetuses with a gestation age of 9.5 to 24 weeks. During this period it was possible to follow up the main morphogenetical events, beginning with the appearance of the first radial folds up to the occurrence of ciliary processes with a rather adultlike arrangement. The ciliary processes observed during week 24 differed from those of the adult eye only by their dimensions and the lack of surface infoldings. A primitive pars plana could only be identified during week 24. The morphological basis for aqueous humor production is discussed.
通过扫描电子显微镜对妊娠9.5至24周的人类胚胎和胎儿的睫状体发育进行了检查。在此期间，可以追踪主要的形态发生事件，从最初的放射状褶皱出现到具有相当成熟排列的睫状突的发生。在第24周观察到的睫状突与成年眼睛的睫状突仅在尺寸和缺乏表面褶皱方面有所不同。仅在第24周时才能识别出原始的睫状体扁平部。本文还讨论了房水生成的形态学基础。
