A measurement system takes measurements of intraocular pressure and displaced ocular volume for determination of aqueous outflow resistance A device with a &pgr;gid outer wall, a flexible inner wall, and an inflatable bladder in between is placed over the eye A pressure measurement system is coupled to the bladder and is configured to measure a pressure of fluid within the bladder A hydraulic unit is coupled to the bladder and configured to control a flow of fluid between the bladder and an external reservoir, and to measure a change of volume in the bladder created by the pressure applied to the eye Both the pressure measurement system and hydraulic unit are directly controlled by and communicated with a microprocessor/computer In addition, the microprocessor computes the outflow resistance of the eye as a function of the pressure in the bladder and the change of volume in the bladder over time.
