Interpreting the IOP Measurement
During the measurement, the LCD shows the cumulative number
of applanations detected. Once 10 applanations are achieved, the
LCD will display the IOP in millimeters of mercury (mm Hg), along
with a statistical confidence indicator.
A statistical confidence indicator of 95 means that the standard
deviation of the valid measurements is 5% or less of the number
shown. The higher the statistical confidence indicator, the more
reliable the measurement.
If the statistical confidence indicator is 80 or 80-, a repeat
measurement is recommended.
