Abstract
The non-contact tonometer can measure intracocular pressure without touching the eye. A central area of the cornea(3.60 mm in diameter) is deformed by an air-pulse of linearly increasing force and the intant of applanation is determined by amonitoring system that senses light reflected from the corneal surface. The interval of time required for the air-pulse to produce applanation is proportional to IOP. The noncontact tonometer utilize the fundamental principles of applanation tonometry. It is calibrated against the Goldman tonometer. To evaluate non-contact tonometer clinically, intraocular pressure was measured with the non-contact tonometer(NCT) and the Goldman applanation tonometer(GAT) in 174 eyes of 101 subjects with noraml corneas. The results were as follows. Mean intraocular pressue was 15.26±4.07 mmHG with the NCT, and 16.36±4.03 mmHG with the GAT respectively. The correlation coefficient at 0.79 was statistically significant at the p<0.0001 level. The regression analysis equation was y=4.34748+0.78861x. Intraocular pressures were gradually decreased with aging (p<0.05), but there was no sexual difference in intraocular pressure with the NCT and GAT.
