Goldmann眼压计与非接触眼压计测量青光眼患者眼压的对比分析

Comparison of two methods of tonometry in glaucoma patients: Goldmann applanation tonometer and non-contact tonometer

目的:对比分析Goldmann压平式眼压计(Goldmann applanation tonometer,GAT)和非接触眼压计(noncontact tonometer,NCT)测量青光眼患者眼压的结果,寻找其规律性。方法:分别使用GAT和NCT测量108例206眼青光眼患者的眼压。结果:青光眼患者108例206眼的平均眼压:GAT测量为29.77±10.27mmHg,NCT测量为24.59±8.58mmHg,两者比较存在显著性差异(P<0.01),而且眼压越高,差异性越显著。结论:NCT测量值较GAT测量值低,眼压越高,差值越大。建议使用GAT检查青光眼患者的眼压,以免漏诊和贻误治疗。

AIM： To compare the two methods for the measurement of glaucoma patients’ intraocular pressure（ IOP） between Goldmann applanation tonometer（ GAT）and non- contact tonometer（ NCT） and find the laws of the two methods.METHODS： The IOP of 108 glaucoma patients（ 206eyes） were measured by GAT and NCT respectively.RESULTS： In 108 glaucoma patients,the average IOP of206 eyes was 29. 77 ± 10. 27 mmHg by GAT and 24. 59 ±8. 58 mmHg by NCT. There was significant difference between GAT and NCT（ P 〈 0. 01）. The higher of IOP,the difference between GAT and NCT was greater.CONCLUSION： The measurement results with NCT were lower than that of GAT. The higher of IOP,the difference between GAT and NCT was greater. It’s better to measure IOP by GAT for the glaucoma patients,in order to avoid the misdiagnosis and mistreatment of glaucoma.
