Figure 1.
Screenshot of 3 seconds of raw IOP telemetry data showing the identification of troughs (red dots) and peaks (green dots) of the transient IOP fluctuations detected by the FIR filter. Baseline IOP, defined as the portion of the total IOP excluding transient IOP fluctuations, was calculated as the area under the IOP versus time curve bounded by the transient IOP fluctuation troughs (green area), and then averaged during waking hours.
