Studies on the Etiology of Glaucoma Part 2. Relation­ship Between Diencephalon and Intraocular Pressure

The author has carried out the investigations from various angles on the relationship between the function of diencephalon and the eye pressure, and has found that all the evidences in the investigations point to a quite important role being played by the diencephalon in regulation of the eye pressure. Today it is a common physio-anatomical knowledge that the functions such as respiration, pulsation, blood pressure, and digestive actions which are essential for the maintenance of life, all possessing autonomy, are performed and regulated by the centers existing in the diencephalon. Now, the eye pressure, having such an important relationship to the visual functions, can not possibly be a lone exception. From these, therefore, it may be concluded that at least an autonomic center of the eye pressure exists in the diencephalon.
