摘要:目的:探讨眼轴长度(axial length, AL)和角膜曲率半径(corneal radius of curvature, CR)比值(AL/CR)在学龄期儿童近视防控中的临床应用价值。方法:回顾性分析2025年1月1日至2026年4月30日期间在本院眼科就诊的近视儿童50例(100眼),年龄10~12岁,均采用蔡司IOLMaster 700(Carl Zeiss Meditec AG,德国)进行生物测量,随访时间约12个月。依据等效球镜度(SE)分为低度近视组(n=20)、中度近视组(n=20)及高度近视组(n=10)。结果:三组AL/CR比值分别为3.10±0.06、3.34±0.08及3.55±0.12,组间差异有统计学意义(F=187.3,P<0.001);AL/CR 比值与SE呈高度负相关(r=−0.923,p<0.001);随访12个月后,高度近视组AL/CR(0.09±0.03)显著高于低度组(0.04±0.02,p<0.001)。结论:AL/CR比值是反映学龄期儿童近视程度及进展速度的敏感生物测量指标,建议将其纳入常规近视防控随访体系。
