4种不同眼压计测量值的比较

Comparison of Intraocular Pressure Values Measured by 4 Different Tonometers

目的:比较分析非接触式眼压计(NCT)、Icare回弹式眼压计(RBT)、Tono-pen眼压计(TPT)和Goldmann眼压计(GAT)的眼压测量结果,评价不同眼压计在临床的应用价值。方法:收集我院临床患者36例(72眼)分别用NCT、RBT、TPT和GAT眼压计测量眼压,然后根据GAT测得的眼压值分为3组,A组(眼压≤21 mmHg)、B组(21 mmHg<眼压≤30 mmHg)、C组(眼压>30 mmHg),对比分析不同眼压程度分组下各种眼压计的测量结果。结果:NCT-GAT平均差值在A组为(0.22±0.43)mm Hg(t=1.936,P=0.075),B组为(0.90±1.26)mm Hg(t=2.156,P=0.063),C组为(7.94±3.02)mm Hg(t=6.958,P=0.000);RBT-GAT平均差值在A组为(0.55±0.57)mm Hg(t=3.656,P=0.003),B组为(0.05±0.45)mm Hg(t=0.347,P=0.738),C组为(-0.53±1.71)mm Hg(t=-0.825,P=0.441);TPT-GAT平均差值在A组为(-0.66±0.99)mm Hg(t=-2.531,P=0.026),B组为(-0.50±0.62)mm Hg(t=-2.434,P=0.041),C组为(-2.25±2.67)mm Hg(t=-2.223,P=0.068)。结论:NCT、RBT均适用于在临床工作中青光眼的诊断,因眼压≤21 mmHg时,RBT测量的眼压值与GAT相比差异有统计学意义,故最好不用于青光眼随访,TPT仅适用于青光眼筛查。

Objective： To compare and analyze the intraocular pressure （IOP） values measured by non-contact tonometer （NCT） , Ieare rebound tonometer （RBT） , Tono-pen tonometer （TPT） and Goldmann applanation tonometer （GAT） , and to evaluate the clinical application value of different tonometers in measuring IOP. Methods： IOP was measured by NCT, RBT, TPT and GAT tonometers in 36 patients （72 eyes） . The patients were divided into three groups according to IOP measured by GAT, group A （IOP≤21 mmHg）, group B （21 mmHg〈IOP≤30 mmHg）, group C （IOP〉30 mmHg） . Measurement results of different tonometers in different groups were compared and analyzed. Results： The average difference of NCT-GAT in group A was （0.22± 0.43） mmHg （t=1.936, P=0.075）, （0.90±1.26） mmHg in group B （t=2.156, P=0.063）, （7.94±3.02） mmHg in group C （t= 6.958, P=0.000） . The average difference of RBT-GAT in group A was （0.55±0.57） mmHg （t=3.656, P=0.003）, （0.05±0.45） mmHg in group B （t=0.347, P=0.738）, （-0.53±1.71） mmHg in group C （t=-0.825, P=0.441） . The average difference of TPT-GAT in group A was （-0.66±0.99） mmHg （t=-2.531, P=0.026）, （-0.50＋0.62） mmHg in group B （t=-2.434, P= 0.041） , （-2.25±2.67） mmHg in group C （t=-2.223, P=0.068） . Conclusions： Both NCT and RBT are suitable for the diagnosis of glaucoma in clinical practice. Because the measurement result with RBT is significantly different compared with GAT when IOP is ≤21 mmHg , it is not recommended for glaucoma follow-up. TPT is only suitable for glaucoma screening.
