This study found that transient IOP fluctuations from blinks, saccades, and ocular pulse are frequent (10,000/hour), large (up to 14 mmHg), and contribute significantly (12%) to total ocular mechanical stress, suggesting single IOP measurements are insufficient.

24-hour IOP telemetry in the nonhuman primate: implant system performance and initial characterization of IOP at multiple timescales.

A new implant continuously monitored nonhuman primate IOP, revealing significant, rapid fluctuations (up to 10 mmHg) and high day-to-day variability, suggesting single IOP measurements may be insufficient for glaucoma management.
