    Regeneration of the human corneal endothelium (1981)

    Notizen: Abstract The ability of the human corneal endothelium to regenerate is studied with the scanning electron microscope through examples of corneal diseases and penetrating keratoplasties. This study does not lead to final conclusions on the possibilities of regeneration of the human corneal endothelium but allows us to say that: regeneration occurs through size increasing and deformation of the remaining cells. the increase in number and size of surface microvilli may simply indicate a state of cell activation. the présence of two nuclei in one cell is probably obtained by amitotic division but no complete mitosis has been seen. Displacement of endothelial cells is a real progression and the cell is able to overcome obstacles. the fibroblastic transformation of the endothelial cells is present in man but this may simply represent the migrating form of the cells.

    The development of the irido-corneal angle in the chick embryo (1980)
    Springer

    Notizen: Abstract The iridocorneal angle of the chick embryo was examined by scanning electron microscopy from the 7th day to the 19th day of development. The mesodermal tissue situated between the corneal endothelium and the iris differentiated into trabecular cells. These cells formed a strip on the 9th day and enlarged on the 13th day to form long cellular fibres. The trabecular meshwork was recognizable on the 15th day and reached full development only on the 19th day. The development of the trabecular meshwork was probably much earlier than is usually described. It began with differentiation of the corneal endothelial cells and these cells acquired a multipolar cell body with long cellular processes. The last stage is probably regulated to avoid an abnormal development of the angle structure. These results can be correlated with those obtained in the morphological examination of the structure of the angle in congenital glaucoma and the “cleavage syndrome” of the anterior chamber.
