Simultaneous Measurement of Changing Intraocular Pressure and Outflow Facility in the Vervet Monkey by Constant Pressure Infusion.

The sources of error and the optivial design of an anterior chamber infusion method for the study of rapid changes in outflow facility and intraocular pressure are discussed, with a series of definite recommendations. A saline solution for anterior chamber infusion that preserves the outflow resistance of the monkey eye has been described. Data are given showing the degree of uncertainty, caused by random factors, of measurements of outflow facility and intraocular pressure with the two-level constant pressure infusion method.
