目的：探讨水平角膜直径(WTW)、水平前房直径(HACD)与水平睫状沟直径(S-S)间的相关性和影响因素。

方法：回顾性研究。收集我院2015-08/2016-08高度近视患者62例115眼，用SIRIUS眼前节分析系统测量WTW和HACD，UBM测量S-S，对比分析测量结果。

结果：所有患者中，WTW为11.91±0.37mm，HACD为12.45±0.43mm，S-S为11.78±0.46mm； 且HACD和S-S与年龄呈负相关(r=-0.423、-0.386，均P<0.05)； 与中央前房深度(ACD)的相关性比较：ACD≤3.5mm组中WTW、HACD与S-S有相关性； ACD>3.5mm组中WTW、HACD与S-S无明显相关关系。

结论：(1)WTW与S-S相关性更好，受年龄、前房深度影响，患者年龄≥40岁或ACD>3.5mm时建议参照UBM测量S-S对ICL型号进行确定；(2)SIRIUS测量的WTW、HACD安全、简单、重复性好。

METHODS: A total of 62 cases(115 eyes)with high myopia were collected from those who were examined in our hospital from August 2015 to August 2016. Their WTW and HACD were measured with SIRIUS, while S-S was measured with UBM, and the results were compared and analyzed.

RESULTS: In all patients, WTW was 11.91±0.37mm, HACD was 12.45±0.43mm, S-S was 11.78±0.46mm. There was negative correlation between HACD or S-S and age(r=-0.423 and r=-0.386 respectively, all P<0.05). Correlation comparison with central anterior chamber depth(ACD)showed in group with ACD≤3.5mm, WTW and HACD were related with S-S; while in group with ACD>3.5mm, there was no significant correlation between WTW or HACD and S-S.

CONCLUSION: 1)WTW and S-S has better correlation, but due to the influence of age and anterior chamber depth, S-S is recommended to be measured with reference to the UBM to determine ICL when the patient is equal to or over 40 years old or with ACD>3.5mm; 2)SIRIUS Anterior Segment System is safe, simple and repeatability in measuring WTW and HACD.
