摘要：

目的 评估散瞳对光学生物测量仪Lenstar LS900检测儿童眼球生物参数的影响。方法 选取30名儿童（58眼）作为研究对象，年龄5~13岁，中位数9.4岁；男性16名（30眼），女性14名（28眼）。在使用复方托吡卡胺滴眼液散瞳前后，采用Lenstar LS900分别对30名儿童（58眼）进行眼轴长度（AL）、角膜中央厚度（CCT）、前房深度（ACD）、角膜曲率（K1和K2）、白到白距离（WTW）、瞳孔直径（PD）及晶体厚度（LT）的测量，采用Pearson相关分析和t检验进行数据分析。结果 AL、ACD、CCT，散瞳前分别为（23.81±1.23）mm、（3.56±0.21）mm和（539.62±24.88）μm，散瞳后分别为（23.84±1.23）mm、（3.63±0.21）mm和（550.55±24.77）μm。统计学分析结果显示：散瞳后AL、ACD、CCT和PD显著大于散瞳前，差异有统计学意义（P<0.05）。男性和女性受检者散瞳前后CCT的变化值分别为(12.63±6.12) μm和(9.11±4.87) μm，男性CCT的变化显著大于女性（t=2.42, P=0.02）。散瞳前后K1、K2、LT及WTW无明显变化。结论 Lenstar LS900 可用于儿童眼球生物参数的测量，散瞳对AL、ACD和CCT有一定影响，尚需进一步扩大样本量进行评估。

Abstract:

Objective To evaluate the effects of cycloplegia on children’s biometric parameters measured by the optical biological measuring instrument Lenstar LS900. Methods A total of 30 children (58 eyes) were selected as subjects. Their age was between 5 and 13 and the mean age was 9.4. Sixteen of them were males (30 eyes) and 14 were females (28 eyes). The axial length (AL), central corneal depth (CCT), anterior chamber depth (ACD), corneal curvature (K1 and K2), white to white (WTW), lens thickness (LT), and pupil diameter (PD) before and after cycloplegia by compound tropicamide eye drops were measured by Lenstar LS900. Data were analyzed by t test and Pearson coefficient analysis. Results The AL, ACD, and CCT values before cycloplegia were (23.81±1.23) mm, (3.56±0.21) mm, and (539.62±24.88) μm and those after cycloplegia were (23.84±1.23) mm, (3.63±0.21) mm, and (550.55±24.77) μm. Results of statistical analysis showed that AL, ACD, CCT, and PD after cycloplegia were markedly larger than those before cycloplegia and differences were statistically significant (P<0.05). Changes of CCT before and after cycloplegia of males and females were (12.63±6.12) μm and (9.11±4.87) μm. Changes of CCT of males were markedly larger than those of females (t=2.42, P=0.02). Changes of K1, K2, LT, and WTW before and after cycloplegia were not significant. Conclusion Lenstar LS900 can be used to measure children's biometric parameters. Cycloplegia has certain effect on ACD, AL, and CCT. But more samples are needed for further evaluation.
