摘要背景 Icare回弹式眼压计作为一种新式眼压计,有必要对它的临床应用价值进行评估.目的 通过比较分析Icare回弹式眼压计和Goldmann压平眼压计(GAT)的眼压测量结果,探讨Icare的临床价值.方法可疑青光眼、青光眼、屈光不正及部分健康体检者78例共152眼同时接受Icare、GAT眼压测量,受检眼先行Icare测量,然后再进行GAT测量,2次测量间隔3～5 min.对比分析两种眼压计的测量结果.结果使用Ieare和GAT测得的眼压均值分别为(19.16±5.03)mmHg和(18.41±4.52)mmHg,96眼(63.2%)两者的眼压差值≤1 mmHg,二者的测量值差异虽有统计学意义,但二者的变化呈明显正相关(r=0.940,P<0.01).当Icare眼压测量值<16 mmHg时,Icare的眼压测量值低于GAT,而当Icare眼压测量值≥16 mmHg时恰好相反;CCT偏薄、正常以及偏厚的情况下,Icare的眼压测量值均高于GAT的眼压测量值.Icare、GAT的眼压测量值和CCT间呈正相关(r=0.341,P<0.01;r=0.333,P<0.01).结论 与GAT眼压计比较,Icare回弹式眼压计易操作,测量结果可靠.临床实用性更强.

abstractsBackground As a new tonometer,it is necessary to assess the clinical value of Icare rebound tonometer.Objective This study was to compare the intraocular pressure(IOP)values measured by Icare with that measured by GAT,and discuss the clinical value of leare rebound tonometer. Methods IOP measurement was performed on 152 eyes of 78 subjects with suspicious glaucoma,glaucoma,refractive error and normal examinnee by Icare and GAT respectively.The Icare IOP was measured firstly and then the GAT IOP was carried out with the 3-or 5-minute interval.The IOP values were compared between Ieare and GAT.This study was approved by Ethic Committee of Wuhan General Hospital of Chinese PLA.Written informed consent was obtained from each subject prior to this study. Results The mean IOP values of Icare and GAT were(19.16±5.03)mmHg and(18.41±4.52)mmHg respectively.The differences between Icare IOP and CAT IOP were less than or equal to 1 mmHg in 96 of 105 eyes(63.2%).The positive correlation was found between the Icare IOP and GAT IOP(r=0.940,P<0.01).The Ieare IOP was lower than that of GAT when IOPIcare<16 mmHg,however,the IOP of Icare were higher when IOPIcare≥6 mmHg;the IOP of Icare were higher than that of GAT in the total CCT range.The correlation coefficients of IOP of Icare or CAT with CCT were 0.341(P<0.01)and 0.333(P<0.01),respectively. Conclusion Compared with GAT,Icare is more feasible in clinic because it is practicable and reliable.
