OBJECTIVE: WE AIMED TO COMPARE INTRAOCULAR PRESSURE (IOP) MEASUREMENTS VIA THREE
DIFFERENT TONOMETERS: the Goldmann applanation tonometer (GAT), the Tono-Pen(®)
XL (TPXL), and a non-contact airpuff tonometer (NCT). METHODS: This was a
cross-sectional study of 200 eyes from 200 patients. Right eyes of all patients
were included in this study. IOP was measured via GAT, NCT, and TPXL by three
physicians. Each physician used one of the tonometers. Measurements via the three
devices were compared. RESULTS: The mean IOP was 15.5±2.2 mmHg (range 10-22) with
the GAT, 16.1±3.0 (range 9-25) with the TPXL, and 16.1±2.8 (range 10-26) with the
NCT. Bland-Altman analysis showed that the mean difference between measurements
from the NCT and the GAT was 0.6±2.3 mmHg. The mean difference between the TPXL
and GAT measurements was 0.7±2.5 mmHg. The mean difference between the NCT and
TPXL measurements was -0.02±3.0 mmHg. There was no significant difference between
the groups according to a one-way analysis of variance (ANOVA) test. P-values
were 0.998 for NCT-TPXL, 0.067 for NCT-GAT, and 0.059 for TPXL-GAT. CONCLUSION:
The NCT and TPXL provide IOP measurements comparable to those of the gold
standard GAT in normotensive eyes.
