摘要

Purpose: Noncontact tonometers are useful when regulations preclude use of contact tonometers by medical students and other nonophthalmologists. Our study compared the measurements by the portable, noncontact tonometer (PT100) with Goldmann applanation tonometry (GAT). Methods: This was a prospective study of 98 eyes from 98 patients. Intraocular pressure (IOP) was measured by GAT and the PT100 (Reichert, Buffalo, NY).Results: Mean IOP measurements showed no significant differences in measurements performed by the two tonometers (P = 0.64). Measurements by the two tonometers were in agreement by ≤3 mmHg in 92.8% of eyes. Linear regression analysis of PT100 vs GAT measurements revealed a slope of 0.98 with r2 = 0.58. Bland–Altman analysis showed a mean difference of measurements by GAT and PT100 of -0.3 mmHg with two standard deviation = 7.1 mmHg.Conclusion: The portable noncontact PT100 tonometer provides IOP measurements comparable to GAT within the normal range of IOP.
