My interest in the relation of intraocular pressure to hemorrhages of the retina was awakened by an article by Igersheimer,1 and 1 began a systematic study of the tonometric readings of the eye in all patients sent to me for ophthalmologic examination with diseases in which complications involving the retina are frequent, the most important of these being retinal hemorrhage.

Igersheimer, after a brief discussion of the physiology of the eye, maintained that pressure outside the vascular walls, represented in the eyeball by the intraocular tension, may have an appreciable influence on the passage of fluid through the walls of the vessels. Only in certain conditions can this pressure be increased without the use of artificial methods. These conditions are fulfilled in the case of closed cavities, such as the eye or the cranium. I shall not discuss the observations and clinical details on which he founded his hypothesis,
