[Quantitative anatomical study of the fetal optic chiasmal capillaries].
The spatial distribution of capillaries in the optic chiasma was studied quantitatively in 51 fetuses, 8 newborns and 4 babies to reveal that the capillary density was lower in the chiasmal median portion, which was therefore a weak point of blood supply. This finding may be a contributing factor for bitemporal hemianopsia due to neoplasms from the sella turcica.
