回弹式眼压计在先天性青光眼患者眼压测量中的临床评价

Clinical evaluation of the rebounder tonometer in patients with congenital glaucoma

目的通过与手持压平式眼压计和Schi觟tz眼压计进行比较评价回弹式眼压计在先天性青光眼患者眼压测量中的价值。设计诊断技术评价。研究对象北京同仁眼科中心连续接受眼压测量的平均年龄(12.0±3.0)个月的先天性青光眼患者29例(29眼)。方法应用回弹式眼压计、Perkins手持压平式眼压计、Schi觟tz眼压计测量眼压,每种眼压计测量眼压重复三次。主要指标眼压值,Pearson相关系数(r)。结果回弹式眼压计、Schi觟tz眼压计和压平式眼压计所测眼压平均值分别为(19.3±8.5)mm Hg、(21.1±10.8)mm Hg和(18.5±7.8)mm Hg(F=0.61,P=0.55)。回弹式眼压计与手持压平眼压计的平均差值为(0.8±2.4)mm Hg。Schi觟tz眼压计与手持压平眼压计平均差值为(2.6±2.4)mm Hg,Schi觟tz眼压计与回弹眼压计的平均差值为(1.8±2.4)mm Hg。回弹式眼压计与手持压平式眼压计(r=0.934,P=0.000)、Schi觟tz眼压计(r=0.933,P=0.000)眼压值均显著相关。结论回弹式眼压计的准确性可满足先天性青光眼患者眼压测量的需求。

Objective To evaluate the clinical value of the rebounder tonometer （RBT） in congenital glaucoma by comparing with Perkins applanation tonometer and Schititz tomometer. Design Evaluation of diagnostic techniques. Participants 29 cases （29 eyes） of the congenital glaucoma patients aged 12.0 ± 3.0 months who were measured intraoeular pressure （lOP） in Beijing Tongren Eye Center. Method lOP was measured with the rebound tonometer, Schititz tonometer and Perkins applanation tonometer. Measurements were re- peated three times each tonometer. Main Outcome Measures lOP values and Pearson correlation coefficient. Results Mean lOP values obtained by RBT, Schititz and Perkins tonometer were 19.3±8.5 mm Hg, 21.1±10.8 mm Hg, and 18.5±7.8 mm Hg, respectively （F=0.61, P=0.55）. The difference of IOP values among three tonometers was not significant. The average difference between RBT and Perkins tonometer was 0.8±2.4 mm Hg. The average difference between Schioetz and Perkins tonometer was 2.6±2.4 mm Hg. The average differ- ence between Schititz and RBT was （1.8＋2.4）mm Hg. The values of Perkins applanation tonometer were significant correlated with RBT （r=0.934,P=-0.000） and Sehititz （r=0.933,P=-0.000）. Conclusion The accuracy of rebounder tonometer can meet the IOP measurement needs in congenital glaucoma patients. （Ophthalmol CHN, 2012, 21： 278-281）
