目的：探讨深度光相干断层扫描(DRI-OCT)联合IOL Master 500在测量近视儿童脉络膜厚度及眼轴长度(AL)中的应用，并分析脉络膜厚度与AL的关系。

方法：前瞻性研究。选取2021年8月至2024年8月收治近视儿童210例210眼(双眼近视程度不一致时，选择严重眼入组； 双眼近视程度一致时，选择右眼入组)。按照等效球镜度数(SE)分为低度近视组(-3.00 D结果：四组参与者的年龄、性别、居住地比较均无差异(均P>0.05)，眼压、SE、AL、不同方位脉络膜厚度比较均有差异(均P<0.001)。Pearson法分析结果显示AL与脉络膜厚度均呈负相关(均P<0.001)，多元线性回归分析结果显示，眼压、SE、AL是影响脉络膜厚度的影响因素(均P<0.001)。

结论：DRI-OCT联合IOL Master 500能够较好地检测脉络膜厚度及AL，脉络膜厚度与眼压、SE及AL水平相关。

METHODS: Prospective study. A total of 210 pediatric myopia patients(210 eyes)admitted between August 2021 and August 2024 were enrolled. Based on spherical equivalent(SE)measurements, they were categorized into a low myopia group(-3.00 D RESULTS:There were no significant differences in age, gender, or place of residence among the four groups of participants(all P>0.05). Intraocular pressure, SE, AL, and choroidal thickness at different locations all showed significant differences(all P<0.001). Pearson correlation analysis revealed that AL negatively correlated with choroidal thickness(both P<0.001). The results of multiple linear regression analysis indicate that intraocular pressure, SE, and AL are factors influencing choroidal thickness(all P<0.001).

CONCLUSION:DRI-OCT combined with IOL Master 500 is able to detect choroidal thickness and AL well, in addition, choroidal thickness closely correlated with intraocular pressure, SE and AL levels.
