ResumoObjective:To assess the agreement of tonometers available for clinical practice with Goldmann applanation tonometer (GAT), the most commonly accepted reference device. Design:A systematic review and meta-analysis of directly comparative studies assessing the agreement of one or more tonometers with the reference tonometer (GAT). Participants:A total of 11,582 participants (15,525 eyes) were included. Methods:Summary 95% limits of agreement were produced for each comparison. Main Outcome measures:Agreement, recordability and reliability. Results:A total of 102 studies, including 130 paired comparisons were included representing eight tonometers (Dynamic Contour Tonometer, Non-contact Tonometer [NCT], Ocular Response Analyser, Ocuton S, Handheld Applanation Tonometer, Rebound Tonometer, Transpalpebral and Tonopen).The agreement (95% limits) appeared to vary across tonometers; 0.2 mmHg (-3.8 to 4.3 mmHg) for NCT to 2.7 mmHg (-4.1 to 9.6 mmHg) for Ocuton S. The estimated proportion within 2mmHg of GAT ranged from 33% (Ocuton S) to 66% and 59% (NCT and Handheld applanation tonometers respectively).Substantial inter-and intra-observer variability was observed for all tonometers. Conclusions:NCT or Handheld applanation tonometers appear to achieve a measurement closest to GAT.However, there was substantial variability in measurements both within and between studies.
