【摘要】： 目的：本研究目的是应用回弹式眼压计(rebound tonometer,RBT)与压平式眼压计(goldmann applannation tonometer,GAT)非接触眼压计(non contact tonometer, NCT)测量玻璃体切割术后患者术眼眼压,观察RBT眼压计测量的可靠性,准确性。方法：选取2009年6月-2009年12月于我院行经睫状体扁平部玻璃体切割术的患者52例(52只眼),年龄7-83岁(平均50.7±19.27岁),分成二组(术后气体／全氟丙烷填充眼,n=35；术后液体／硅油填充眼,n=17),分别比较术后3天RBT眼压计与GAT眼压计,NCT眼压计测量值的差异。三种眼压计测量顺序随机,且每种眼压计的测量均间隔5分钟。所有患者均重复测量三次并取其平均值。采用完全随机方差分析统计数据.直线回归考察任意两种眼压计的相关性,Bland-Altmann考察任意两种眼压计的一致性。统计工作由SPSS软件完成。结果：玻璃体切割术后气体／全氟丙烷(C3F8)填充组即Group1组：GAT眼计测量值17.83±5.95mmHg,NCT眼压计测量值为19.35±5.71 mmHg,RBT眼压计测量值19.10±7.92 mmHg。RBT测量值有65.7%与GAT的差值在±3mmHg之内,与NCT有40.0%。RBT眼计与后两种眼压计呈高度相关性(RBT与GAT R2=0.62,P0.001,RBT与NCT R2=0.16,P0.05)。而玻璃体切割术后液体／硅油填充眼(SOL)填充组即Group2组：三种眼压计测量的总体均数值,GAT眼压计测量值15.35±5.34mmHg,NCT眼压计测量值为17.45±5.88 mmHg,RBT眼压计测量值16.56±6.36 mmHg。RBT测量值有70.6%与GAT的差值在±3mmHg之内,与NCT有70.6%。RBT眼压计与后两种眼压计呈高度相关性(RBT与GATR2=0.60,P0.001,RBT与NCT R2=0.51,P0.001)。Bland-Altmann分析得出：Group1组呈现RBT与GAT, NCT眼压计测量值的变化出现低眼压低估,高眼压高估趋势。Group2组没有出现RBT与NCT眼压测量值的变化出现高估或低估趋势。结论：RBT及GAT、NCT的眼压测量值均可以反应玻璃体切割术后患者眼内压的水平。RBT较GAT/NCT眼压计由于一致性范围较大,因此玻璃体切割术后患者使用RBT眼压计测量眼压并不能替代GAT/NCT眼压计的测量。
[Abstract]:Objective: the purpose of this study was to measure the intraocular pressure of patients after vitrectomy by using the rebound intraocular barometer (IOP) and the non-contact contact tonometer (NCTT), and to observe the reliability and accuracy of the RBT IOP measurement. Methods: from June 2009 to December 2009, 52 patients (aged 7-83 years, mean 50.7 卤19.27 years) undergoing transciliary flat vitrectomy in our hospital were divided into two groups (gas / perfluoropropane filled eye 35; Liquid / silicone oil was used to fill the eye, and the difference between RBT and GAT IOP was compared 3 days after operation. The order of measurement of three kinds of IOP was random. All patients were measured three times repeatedly and their average values were taken. The statistical data of complete random variance analysis were used. The linear regression analysis was used to investigate the correlation between any two kinds of IOP and Bland-Altmann test. The statistical work is done by SPSS software. Results: after vitrectomy, the gas / perfluoropropane C _ 3F _ (8) filled group (Group1 group) was 17.83 卤5.95mm HGAT, and the measured value was 19.35 卤5.71mm mmHg.RBT. The difference between the measured value of GAT and that of gas / perfluoropropane C _ 3F8 (65.7%) was within 卤3mmHg. There was a high correlation between 40.0%.RBT ophthalmometer and the latter two kinds of intraocular pressure gauges with NCT. RBT and GAT R2O0.62P0.001RBT and NCT R2O0.16P0.05. The group filled with liquid / silicone oil filled with SOL after vitrectomy was the Group2 group: the total mean value of three kinds of IOP gauges was gat IOP. The measured value of 15.35 卤5.34mm HgGT IOT was 17.45 卤5.88mm Hgt, and the difference between GAT and GAT was 70.6% (16.56 卤6.36 mmHg.RBT), and the difference was within 卤3mmHg (P < 0.05). There was a high correlation between 70.6%.RBT IOP and the latter two kinds of IOP. RBT and GATR2P 0.001RBT and NCT R2O0.51 P0.001N. Bland-Altmann analysis showed that RBT and GATT were present in group 1, and the change of IOP measured by NCT was low intraocular pressure (IOP). High IOP overestimation. Group 2 showed no tendency to overestimate or underestimate RBT and NCT IOP measurements. Conclusion both the intraocular pressure measurements of% RBT and GATT NCT can reflect the intraocular pressure level of the patients after vitrectomy. RBT is more consistent than the GAT/NCT IOP. Therefore, RBT IOP measurement is not a substitute for GAT/NCT IOP measurement after vitrectomy.
