Score
An advanced signal “scoring” process is employed in the Reichert 7CR to objectively determine
the reliability of the measurement data. On a scale of 0 to 10, the higher the score, the more
reliable the measurement data.
Note:
The IOP measurements (IOPcc, IOPg) and the Score are related but not directly linked.
The IOPcc and IOPg are pressure readings. The Score is an indication of the
reliability
of
the measurement. IOPcc compensates for the biomechanical properties of the cornea and
has been shown to be less affected by corneal properties than other methods of tonometry.
IOPg is essentially equivalent to the measurement a Goldmann type tonometer would
provide, and does not account for the biomechanical properties of the cornea.
Intelligent Averaging of Data
The Reichert 7CR features an intelligent averaging system, based on the waveform score, to help
ensure the most reliable measurements are displayed. The system works in the following manner:
Single Measurements
If a single measurement is taken on an eye, the IOPcc, IOPg and Score for that measurement will
be displayed regardless of the Score. If the Score is low, another measurement should be taken.
Multiple Measurements in Intelligent Averaging Mode
If multiple measurements are made on an eye, the displayed result will be an average of
the measurements with Scores that are within 1 number of the highest score obtained. Any
measurement in a series of measurements with a Score more than 1 below the highest Score
will be discarded. Results from any measurement that produces a score more than 1 number
higher than all other measurements obtained will be displayed based on this result alone.
Note:
The intelligent averaging process updates the displayed results in “real time.” Results
from each measurement in a series of measurements are not displayed individually.
Straight Averaging of Data
When the straight averaging option is selected in the setup menu, the displayed result will be an
average of all measurements regardless of the score.
Multiple Measurements Using the Multi Measurement Button
When using the multi measurement mode the displayed result will be a straight average.
If the multi measurement button is pressed again, the process will start over, clearing the
previous measurements, and replacing any stored values for that eye.
Multiple Measurements Using the Single Measurement Button
When taking multiple measurements using the single measurement button the displayed
results will continue to be updated based on a straight average of all measurements made,
up to the amount of measurements selected in the tonometer setup menu (3 or 4).
Once the maximum number of measurements have been made (3 or 4), an additional
measurement will replace the measurement with the lowest Score, so that only 3 or 4
measurements are averaged together. Each following measurement will continue to replace
the measurement with the lowest Score.
