手持式非接触眼压计测量值准确性的比较

Evaluation of Accuracy of Measuring Intraocular Pressure by Handheld Non-contact Applanation Tonometer

目的:对手持式非接触眼压计测量眼压的准确性及可靠性进行评价。方法:分别采用keeler,手持非接触眼压计和R900,Goldmann压平眼压计对58例患者(113只眼)的限内压进行了测量并对两种测量方法的测量结果进行了比较。结果:采用手持非接触眼压计测得的平均眼压为16.31±5.59mmHg(1mmHg=0.1333kpa),采用Goldmann压平眼压计测得的平均眼压值为17.49±6.13mmHg。经统计学t检验,两种测量结果差别无统计学意义(P>0.05)。经直线相关和回归分析发现两种方法测量值间存在正相关(r=0.8942,b=0.8154)。结论:手持非接触眼压计同Goldmann压平眼压计相比具有同样的精确性和可靠性,可用于青光眼临床和青光眼筛选。眼科学报 1995;11:86—88。

Purpose: To evaluate the accuracy of measuring intraocular pressure by handheld non-contact applanation tonometer.Method:58 patients' (113 eyes) intraocular pressure were measured by Keeler, non-contact tonometer and R 900 Goldmann applanation tonometer and the results of measurement of intraocular pressure by the two kinds of tonometers were compared.Result: The mean intraocular pressure measured by non-contact is 1 6 . 31 ± 5. 59mmHg and 17. 49±6. 13mmHg(1mmHg = 0. 1333kPa) by Goldmann applanation tonometer, respectively. There was no statistical significance to be found (P>0. 05) between the two methods. By linear correlation and regression analysis, a positive correlation was found between the two methods (r = 0. 8942, b = 0.8154).Conclusion : The handheld non-contact tonometer has the same accuracy and reliability of measurement of intraocular pressure comparing with Goldmann applanation tonometer, and it can be used in glaucoma clinic and screening.
