Abstract

I. Introduction  Ophthalmodynamometry has been used primarily as a clinical diagnostic aid. The basic instrument and principles of ophthalmodynamometry as established by Bailliart in 19171 have remained essentially unchanged despite the recent resurgence of interest in this technique. However, opththalmodynamometry has not been fully utilized as an investigative procedure. This has been due to the nature of the Bailliart instrument and to the method with which it is applied to humans.Recently a transparent plastic plethysmographic goggle-type ophthalmodynamometer has been developed in which air pressure may be evenly exerted and maintained on the eyeball. This device is well adapted for experimental work and is described in detail in a separate publication.2 An initial investigation has been reported wherein pupillary reactions and eye movements were tested at pressures sufficient to cause blackout while wearing the goggle.3The purpose of the present study was to determine changes in central
