【摘要】  　　目的：观察白内障患者手术年龄与眼轴长度的关系。方法：收集我院2001/2004共1 004例初次白内障患者手术的年龄、眼轴长度，按眼轴长度分A、B、C 3组，比较各组手术年龄，并对手术年龄和眼轴长度作相关分析。结果： 眼轴长度为C组，白内障患者手术年龄平均为（64.25±8.0）岁，而眼轴长度为A组,手术平均年龄仅为67.44±9.16岁，差异显著（P =0.002）。手术年龄与眼轴长度有较弱的负相关，r =-0.25,P =0.015。结论：随眼轴长度的增加，白内障患者手术年龄出现年轻化趋势。

    Abstract AIM: To investigate the relation of axial length and the age of patients undergoing cataract.Methods: Ages and axial lengths of 1 004 patient undergone cataract surgery from 2001 to 2004 were recorded and collected. The patients were divided into three groups (A, B and C) according to the axial length. The age at cataract surgery and correlation between age and axial length were analyzed. RESULTS: The means age (years) at cataract surgery in group C was significantly lower than that in group A (64.25±8.0vs 67.44±9.16, P=0.002). There are less significant correlation between the age at cataract surgery and the axial length (r=-0.25, P=0.015).  CONCLUSION: Age at cataract surgery tends to become lower with the increasing of the axial length of the eye.

　　0引言

    随着人口增加和老龄化，我国年龄相关性白内障患者的比例急剧增加；同样，在我国近视眼比例也呈增加趋势，尤其在青少年中，近视眼患病率位居全球第二，实际总人数全球第一。在近视眼中，以轴性近视眼居多，轴性近视眼形成，将对眼球的结构产生较多改变，同时增加眼部相关并发症的出现：青光眼、白内障、视网膜脱离等，严重威胁视觉健康。目前，我国现有的白内障就诊人群是否，已受到近视眼的影响，并不所知。现回顾性分析我院近3a来，就诊的白内障患者中，眼轴变化与白内障手术年龄之间的相关性。
