Transpalpebral measurement of intraocular pressure using the Diaton tonometer versus standard Goldmann applanation tonometry

Background Diaton transpalpebral tonometry is a new version of TGDc-01 transpalpebral tonometry. The aim of this study is to evaluate the reliability of this method, and to compare the results with those of corrected Goldmann applanation tonometry (c-GAT), which is the “gold standard” for the clinical measurement of IOP. Methods IOP was measured in 212 eyes of 129 subjects by means of two different methods. Measurements with two tonometers were performed in random order, and the measurements of central cornea thickness were performed with ultrasound pachymetry. Results The average IOP reading was 15.46 ± 5.68 mmHg for c-GAT and 13.84 ± 5.12 mmHg for Diaton tonometer. The mean difference between c-GAT and Diaton tonometer was 1.62 ± 3.60 mmHg (p
