[Evaluation of the hypothalamo-hypophyseal-thyroid axis by means of TRH in patients with chronic open-angle glaucoma].
The diencephalo-hypophyseal axis was studied in a group of patients with chronic open-angle glaucoma by means of TRH. Nearly half of the patients studied presented with hypothalamo-hypophyseal dysfunctions. TRH increases the outflow coefficient in these patients but this increase seems to be due to a pharmacodynamic action inherent in the product, and appears prior to the release of thyroid hormone.
