Comparison of the Pulsair noncontact tonometer and the Goldmann applanation tonometer.

We measured the intraocular pressure (IOP) in 100 consecutive new patients (200 eyes) with the Pulsair noncontact tonometer and with the Goldmann applanation tonometer. The correlation coefficient between the two instruments was 0.76 for the first eye tested and 0.90 for the second eye tested. The Pulsair noncontact tonometer may be useful for screening patients presumed to have normal IOP if an appropriately low IOP value is used to indicate the need for further assessment. The calibration of the instrument could be improved.
