A randomized technique of constant-pressure infusion.

A population study of measured inflow values of eyes of a group of adult male rhesus monkeys was done with a randomized technique of constant-pressure infusion. Each eye was presented with a sequence of 18 4-minute runs, consisting of three infusion runs for each of six pressures, in which the order of appearance of a given pressure had been randomized. A statistical analysis of the results indicates that only the independent variables of infusion pressure, type of anesthetic, and position in the sequence of the 18 infusion runs had a significant effect upon measured inflow.
