Effect of two tonometers on measuring normal intraocular pressure

Abstract

Objective To discuss the clinical performance of ICARE rebound tonometer.Methods Intraocular pressure measurements were performed on 112 cases(224 eyes)with non-contact tonometer and ICARE rebound tonometer respectively.Results The intraocular pressure of right eyes which measured by ICARE rebound tonometer was(15.4 ±3.4)mm Hg,and the left eyes' was(15.6 ±3.2)mm Hg on average,but they were(13.5 ±2.7)mm Hg and(13.6 ±2.6)mm Hg respectively measured by non-contact tonometer There was significant difference between the two tonometer(t =4.384,4.535;P ＜0.01).Conclusions lOP measured by ICARE rebound tonometer is higher than that of non-contact tonometer when IOP is in the normal range.ICARE rebound and non-contact tonometer have a good consistency.
