改良Goldmann压平测量法对低眼压眼的检测评价

Modified Goldmann Flattening Measurement for the Detection and Evaluation of Eyes with the Low Intraocular Pressure Value

目的:对于低眼压值眼(IOP≤5mmHg)测量时稳定性不佳测量难度大的临床现状,通过其配套核对砝码改变测量初始值,辅助完成测量从而提高稳定性及易测性的可行性。方法:采用Goldmann压平眼压计仪采集受试者的不同测量初始值(测量0位分别对应旋转测量筒指向0、20、60刻度)的眼压,比较3组受试者眼压测量值有无差异,并探讨眼部手术史对眼压测量的作用。结果:将117例被测眼(低眼压组53眼,正常对照组64眼)的3组眼压数据进行对比分析,低眼压组加砝码的眼压值与无砝码测量结果有统计学差异,但不具有临床意义。而不同砝码测量值之间无明显统计学差异,正常对照组三种方法结果均无明显统计学差异。进一步检验显示按照无手术史、玻璃体切割手术、青光眼手术分类进行影响因素分析后,三组眼压均值间没有明显统计学差异。结论:Goldmann压平眼压计测量正常眼眼压时,使用核对砝码对于各类条件不同的被检眼所测量出的眼压值与不使用核对砝码时无明显差异。对于低眼压眼存在的统计学差异,因不同组间最大0.23mmHg的差异并不具有临床意义。由此在临床应用时,对于测量低眼压眼,可以通过使用核对砝码提高测量初始值,降低测量难度。

Objective:For eyes with the low IOP(intraocular pressure)value(IOP≤5mmHg),the clinical status quo of poor stability and difficulty in measurement,change the initial value of the measurement by reference weights with their companionshi,assist in the feasibility of completing measurements to improve stability and reduce difficulty.Methods:Goldmann-type Tonometers was used to collect the initial value of different measurement pressures(0 digits corresponding to the rotation measuring cylinder pointing to 0,20 and 60 scales)of the subjects,to compare differences in IOP measurements between the three groups and to explore the role of ocular surgery history on IOP.Results:Three sets of the IOP value data of 117 tested eyes(53 eyes in the low pressure group and 64 eyes in the normal group)were compared and analyzed,here was a statistically significant difference between the IOP values of the weights added to the low IOP value group and the measurements without weights.But,it is not clinically significant.Moreover,there was no significant statistical difference between the different weight measurements,and there was no significant statistical difference between the results of the three methods in the normal control group.Further examination showed that the influencing factors were analyzed according to the classification of no surgical history,vitrectomy surgery,and glaucoma surgery,there was no significant statistical difference between the mean the IOP value of the three groups.Conclusion:When Goldmann-type Tonometers measures the normal IOP value,there is no significant difference between the IOP value measured by the eye under different conditions and the IOP value measured when no checking weight is used.there is no significant difference between the IOP value measured by the eye under different conditions and the IOP value measured when no checking weight is used.There was a statistically significant difference in the low IOP eyes,as the maximum difference of 0.23mmHg between groups was not clinically significant.Therefore,in clinical application,for the measurement of the low IOP eye,we can increase the initial value of measurement by using the Refernce weights,reduce the difficulty of measurement.
