摘要
目的:分析非接触式眼压计(non contact tonometer,NCT)、ICare回弹式眼压计(ICare rebound tonometer,RBT)在青光眼患者中眼压测量结果的准确性。方法:回顾性病例对照研究。选取青光眼患者113例185眼。用RBT、NCT和Goldmann眼压计(GAT)分别于9∶00、16∶00两次进行眼压测量并记录为两组数据,分别用秩和检验、国际标准8621指南评估其准确性,Bland-Altman一致性分析两组测量结果的一致性,并以GAT测量值作为标准将数据分为异常眼压组(<10mmHg或>21mmHg)和正常眼压组(10~21 mmHg),在不同组间分析其一致性。应用Spearman相关分析眼压计间的相关性。结果:GAT、NCT和RBT三组测量值间存在差异(P<0.01);GAT获得的眼压测量值与RBT和NCT测量值间存在相关性(r s=0.71、0.77,P<0.001)。NCT与GAT测量值接近(P=0.92),而RBT与GAT相比,眼压测量值较高(P<0.05)。然而NCT、RBT同GAT相比一致性界限范围均较宽,分别为-6.2~6.0、-5.2~7.6mmHg,在正常眼压组一致性界限范围分别为-5.9~5.9、-4.3~7.5mmHg,在非正常眼压组分别为-7.3~6.4、-7.5~5.6mmHg。根据ISO 8612指南进行评价,NCT和RBT在三组中超过95%的一致性限制的异常值分别为3.9%、11.3%、12.2%和26.3%、11.3%、12.2%。结论:NCT和RBT均不能简单代替GAT用于青光眼患者眼压的测量。在青光眼患者中,随着测量值偏离正常眼压范围,NCT和RBT的测量误差也有所增大。
AIM: To analyze the accuracy of non-contact tonometer (NCT) and ICare rebound tonometer (RBT) in measuring intraocular pressure in glaucoma patients. METHODS:A retrospective proportional control study. Totally 113 patients (185 eyes) with glaucoma were studied. Intraocular pressure was measured by RBT, NCT and Goldmann Applanation tonometer (GAT) at 9 ∶ 00 and 16 ∶ 00 and recorded as two sets of data, respectively. Their accuracy is evaluated by the rank sum test, and the international standard 8621 guide, Bland-Altman consistency analysis analyzed the consistency of the two groups of measurements, and the data were divided into two groups: abnormal intraocular pressure group (<10mmHg or >21mmHg) and normal intraocular pressure group (10-21mmHg). The consistency was analyzed between different groups. The spearman correlation analysis is adopted to analyze the correlation between ophthalmotonometers. RESULTS: There were differences among the GAT, NCT and RBT measurements ( P <0.01). There was a strong correlation between the intraocular pressure measured value obtained by GAT and measured values obtained by RBT and NCT ( r s =0.71, 0.77, P <0.001). The measured values of NCT and GAT are close to each other without statistically significant differences ( P =0.92). Compared with GAT, RBT has a higher intraocular pressure measured value, and there are significant differences ( P <0.05). However, compared with GAT, both NCT and RBT have a wide range of limits of agreement, and they are (-6.2 -6.0mmHg) and (-5.2-7.6mmHg) respectively. In normal intraocular pressure groups, the ranges of limits of agreement are (-5.9 -5.9mmHg) and (-4.3-7.5mmHg) respectively. In abnormal intraocular pressure groups, the ranges of limits of agreement are (-7.3- 6.4mmHg) and (-7.5-5.6mmHg) respectively. The evaluation carried out in accordance with ISO 8612 guides indicates that the abnormal values more than the 95% of consistency restriction of NCT and RBT in the three groups are (3.9%, 11.3%, 12.2%) and (26.3%, 11.3%, 12.2%) respect
