Table 3: Summary measures of IOP differences taken with
TonoCare and Perkins AT measurements, summarised overall, and
within 3 IOP subgroups.
†
Based on Perkins AT measured IOP. *Standard deviation.
§
Interquartile range.
** In order to obtain measurements in this range, an inversion procedure was performed on a
subset of participants while taking IOP measurements.
It was concluded by the investigators that there are no clinically
meaningful differences in IOP measurements among the
tonometers, and that the TonoCare conforms to the standard
as detailed.
