To compare intraocular pressure (IOP) measurements obtained by Icare PRO rebound tonometer (RT), Tomey FT-1000 noncontact tonometer (NCT), and Goldmann applanation tonometer (GAT) in healthy subjects, and to investigate the influence of central corneal thickness (CCT) on IOP measurements.
A total of 132 eyes of 66 healthy subjects were included in the study. All IOP measurements were applied in a sitting position and always in the same order (RT, NCT, and GAT). CCT was measured by noncontact anterior segment optical coherence tomography.
The mean CCT was 523.5±31.2 μm. The mean IOPs with GAT, NCT, and RT measurements were 14.56±2.77, 13.42±2.99, 14.18±2.55 mm Hg, respectively. A significantly good agreement was found between RT and GAT measurements (P=0.515). The mean difference between RT and GAT measurements was -0.38 mm Hg. An underestimation was found in NCT measurements compared with GAT ones as defined from paired comparisons (P=0.003). The mean difference between NCT and GAT measurements was -1.14 mm Hg. There was no significant difference between NCT and RT readings (P=0.069). The mean difference between NCT and RT measurements was -0.76 mm Hg. There was a significant correlation between GAT-NCT (r=0.740, P<0.001), GAT-RT (r=0.743, P<0.001), NCT-RT (r=0.729, P<0.001) measurement methods. The increment in measured IOP for a 10 μm increase in CCT was 0.16, 0.33, and 0.18 mm Hg for the GAT, NCT, and RT, respectively.
The IOP readings with the new Icare PRO RT showed good correlation with those obtained by GAT. Tomey FT-1000 NCT underestimated the IOP compared with GAT.
比较Icare PRO回弹式眼压计(RT)、拓普康FT - 1000非接触眼压计(NCT)和Goldmann压平眼压计(GAT)在健康受试者中所测得的眼压,并研究中央角膜厚度(CCT)对眼压测量的影响。
本研究共纳入66名健康受试者的132只眼。所有眼压测量均在坐位进行,且测量顺序始终相同(RT、NCT、GAT)。通过非接触式眼前节光学相干断层扫描测量CCT。
平均CCT为523.5±31.2μm。GAT、NCT和RT测量的平均眼压分别为14.56±2.77、13.42±2.99、14.18±2.55mmHg。RT和GAT测量之间存在显著的良好一致性(P = 0.515)。RT和GAT测量之间的平均差值为 - 0.38mmHg。与配对比较所定义的GAT测量相比,NCT测量存在低估(P = 0.003)。NCT和GAT测量之间的平均差值为 - 1.14mmHg。NCT和RT读数之间无显著差异(P = 0.069)。NCT和RT测量之间的平均差值为 - 0.76mmHg。GAT - NCT(r = 0.740,P < 0.001)、GAT - RT(r = 0.743,P < 0.001)、NCT - RT(r = 0.729,P < 0.001)测量方法之间存在显著相关性。CCT每增加10μm,GAT、NCT和RT测量的眼压增量分别为0.16、0.33和0.18mmHg。
新型Icare PRO RT所测得的眼压读数与GAT所测得的读数具有良好的相关性。与GAT相比,拓普康FT - 1000 NCT低估了眼压。
