摘　　要：目的 通过比较IXT儿童与无显斜儿童眼部生物测量值和屈光状态,观察IXT是否影响儿童眼部生物测量值和屈光状态的关系。方法 回顾性研究,连续选取2023年5月至2023年10月于我院首诊的符合纳入标准的3~12岁儿童共726例为对照组,同期住院治疗的3~12岁单纯IXT患儿173例为斜视组。记录两组右眼数据:眼轴(AL)、平均角膜曲率半径(CR)、睫状肌麻痹验光结果,并计算眼轴/角膜曲率半径比值(AL/CR),等效球镜度(SE),进行统计分析。结果 斜视组与对照组比较,其眼部生物测量值无统计学差异;不同斜视程度组间比较,其眼部生物测量值无统计学差异。斜视组AL/CR与SE相关性最强,AL次之,与对照组一致。斜视组识别近视能力AL的AUC值(0.952)稍大于AL/CR (0.947),斜视组识别远视、对照组识别近视、对照组识别远视能力AL/CR的AUC值均大于AL的AUC值(0.941 vs 0.922、0.963 vs 0.924、0.972 vs 0.941)。斜视组采用AL/CR识别近视、远视的最佳临界值为3.03、2.97;对照组采用AL/CR识别近视、远视的最佳临界值为3.01、2.95。结论 IXT不影响儿童眼部生物测量值,也不影响儿童眼部生物测量值与屈光状态的关系。Objective Observing whether intermittent exotropia affects children's ocular biometric values and refractive status by comparing them with those without exotropia.Methods According to the inclusion and exclusion criteria,726 children aged 3~12were included in the control group,and 173 in the exotropia group.All the right eyes'data of participants were recorded,including axial length(AL),the radius of corneal curvature(CR)and cycloplegic retinos-copy.Counted the ratio of axial length/corneal(AVCR)and spherical equivalent(SE).Statistics were analyzed.Result There were no statistics differences between control group and exotropia group,as well as groups with different degrees of strabismus.As the control group,the relationship between AL/CR with SE was tough also in the exotropia group,AL next.The ability of AL recognize myopia was slightly larger than AL/CR in exotropia group(0.952 vs 0.947),while the rests AL/CR were all better than AL(0.941 vs 0.922、0.963 vs 0.924、0.972 vs 0.941).The cutoff value of AL/CR to recognize myopia and hyperopia was 3.03,2.97 in the exotropia group,while in control group was 3.01,2.95.Conclusion Intermittent exotropia does not affect the ocular biometric measurements and refractive status of children,nor does it affect the relationship between the ocular biometric measurements and refractive status of children.
