[Visual field in the Cushing syndrome (author's transl)].

According to traditional opinion the basophile adenoma, in contrast to the eosinophile or chromophobe tumours of the hypophyse, practically never causes lesion of the chiasm. However, the case of a 16-year-old girl suffering from adiposis, hypertonia, striae distensae and a "full moon face" is used to demonstrate that through the precis examination of the visual field on the Goldmann perimeter even with normal disque of the optic nerve, normal sella turcica established by X-ray, and uncharacteristic hormon condition, a slight chiasmal lesion caused by pressure from below can be established.
