【摘要】：目的比较Oculyzer II眼前节分析系统和A型超声测厚仪对近视患者中央角膜最薄点厚度(TCT)测量结果的差异性、相关性及一致性,为临床的应用提供理论依据。方法回顾性研究2015年7月在安徽医科大学第一附属医院眼科行准分子近视矫正手术的患者102例(204只眼),利用Oculyzer II及A型超声测量的TCT值,对其进行统计学分析。结果 Oculyzer II测量的左右眼TCT均值分别为(540.43±27.69)μm和(541.54±28.63)μm,差异无统计学意义(t=-0.16,P=0.11);Oculyzer系统和A型超声测量TCT的均值分别为(540.99±28.10)μm和(535.80±29.33)μm,差异具有统计学意义(t=10.595,P=0.000),两者的差值平均为(5.181±6.753)μm,线性相关显示两者具有高度正相关性(r=0.973,P=0.000);96.6%的点落在95%的一致性界限内,表明两法具有较好的一致性,95%的一致性界限为(-8.1μm,18.4μm)。结论 Oculyzer II与A型超声在测量角膜最薄点厚度上虽具有高度的正相关性及一致性但也有显著差异性且95%的一致性界限较宽,临床使用中两者可以相互参考,不能替换。
[Abstract]:Objective to compare the difference, correlation and consistency of the central corneal thinnest point thickness (TCT) between the Oculyzer II anterior segment analysis system and the A mode ultrasound thickness meter in myopic patients, so as to provide the theoretical basis for clinical application. Methods 102 patients (204 eyes) who underwent excimer myopia correction surgery in the first affiliated Hospital of Anhui Medical University in July 2015 were studied retrospectively. The TCT values measured by Oculyzer II and A-mode ultrasound were analyzed statistically. Results the mean values of TCT in the left and right eyes measured by Oculyzer II were (540.43 卤27.69) 渭 m and (541.54 卤28.63) 渭 m, respectively. There was no significant difference between the Oculyzer system and the A-mode ultrasound system. The mean values of TCT were (540.99 卤28.10) 渭 m and (535.80 卤29.33) 渭 m, respectively. The difference between them was (5.181 卤6.753) 渭 m and (5.181 卤6.753) 渭 m, respectively. The correlation showed that there was a highly positive correlation (r = 0.973P ~ (0.000) between them, and 96.6% of the points fell within the 95% consistency limit. It is shown that the consistency limit of 95% is (-8.1 渭 m) 18.4 渭 m). Conclusion Oculyzer II and A-mode ultrasound have a high positive correlation and consistency in measuring the thickness of the thinnest point of cornea, but there are also significant differences and a wide consistency limit of 95%. They can refer to each other and cannot be replaced in clinical use.
