comparison of intraocular pressure measurement with the noncontact pulsair 3000 tonometer and goldmann applanation tonometer

purpose: to compare intraocular pressure (iop) measurement with pulsair non-contact tonometer and goldmann applanation tonometer (gat). methods: in this cross-sectional study, during a complete ophthalmologic examination, each patient underwent pulsair tonometry three times at 5 minutes intervals and then goldmann tonometry at the same intervals. mean iop values were measured and analyzed. results: we evaluated 458 eyes of 250 patients (138 males and 112 female subjects). mean iop was 19.45±9.04 mmhg with gat and 20.11±8.42 mmhg with pulsair (p=0.075). correlation coefficient between the two methods was 0.96 (p= 0.004) and the mean difference (pulsair-gat) was 0.65±1.52 (confidence interval 95%, +3.5 to -2.29). with iops between 10-25mmhg, mean difference between the two methods was 0.49±1.23 (p= 0.32) mmhg, however it was -1.75±1.91 (p= 0.06) at iops over than 25 mm hg. conclusion: pulsair tonometry has acceptable accuracy in comparison with gat, especially in iop ranging from 10 to 25 mmhg.
