Table 3 provides the limits of agreement between the HOME tonometer and the two
reference tonometers. All ANSI performance goals were met as less than 5% of
measurements fell outside ± 5 mmHg at each pressure range and less than 1% fell
outside ± 7.5 mmHg at each pressure range.
Table 3. Limits of Agreement between Home and Reference Effectiveness Analysis
Cohort.
N is the number of eyes with measurements from both devices.
Difference = HOME - Reference. 95% confidence interval (CI) for mean difference is based on t-distribution.
95% limits of agreement (LOA) = mean difference ± 2 difference SD.
% = (n / N) x 100.
The first HOME IOP measurement of each study eye was used in the analysis.
Mean/Median: the median was used if the eye had three measurements. Otherwise, the mean was used if the eye had
two measurements.
