Comparison of the Transpalpebral Tonometer TGDc-01 with Goldmann Applanation Tonometry

Comparison of the Transpalpebral Tonometer TGDc-01 with Goldmann Applanation Tonometry

Purpose This study aimed to compare intraocular pressure (IOP) measurements obtained by the transpalpebral tonometer TGDc-01 and by the Goldmann applanation tonometer (GAT). Methods IOP was measured by the conventional GAT and the TGDc-01 tonometer. Central corneal thickness (CCI) was measured for a...

Zusammenfassung:Purpose This study aimed to compare intraocular pressure (IOP) measurements obtained by the transpalpebral tonometer TGDc-01 and by the Goldmann applanation tonometer (GAT). Methods IOP was measured by the conventional GAT and the TGDc-01 tonometer. Central corneal thickness (CCI) was measured for all eyes. Results Sixty-seven consecutive patients (123 eyes) participated. The mean difference between the 2 techniques (TGDc-01-GAT) was −0.93 mmHg, SD=2.74 (p=0.0002, paired t-test), and 70% of the measurements were within ±2 mmHg. The correlation coefficient was 0.67 (p
