BSTRACT We studied two models of noncontact tonometer with respect to reliability of intraocular pressure measurement, when used by a paramedical personnel, comparing with Goldmann applanation tonometry.

The first group of 205 eyes was measured with NT-2000 of Nidek. Another group of 244 eyes was measured with T-2 of Canon. It revealed equal coefficient of correlation (r = 0.84 p < 0.001). Both instruments have properties to be used as a screening test for glau coma detection.
