Figure 3.

The comparison of the mean IOP via pneumatonometry during the study period in both the study and control eye. The baseline value (far left) represents the IOP measurements obtained before wear of the MPD. Only the study eye underwent application of negative pressure. NP = negative pressure; MPD OFF indicates the device was not being worn by the subject during IOP measurement. *The difference between the study and control eye at these time points (25%, 50%, 75%) was statistically significantly different (P < 0.001) than the IOP difference between the study and control eye before the application of negative pressure.
