摘要
目的通过测定不同年龄白内障人群的角膜厚度和角膜曲率,了解其随年龄变化的规律。方法2009年6月至2010年6月于海南亮晶工程接受治疗的白内障患者6 812例,排除角膜溃疡、角膜白斑、圆锥角膜、角膜外伤等角膜疾病者,按照年龄分为5组:A组10~20岁10例,B组20~40岁49例,C组40~60岁527例,D组60~80岁4 709例,E组80岁以上1 517例。测量每个患者的中央角膜厚度和角膜曲率,采用SPSS 11.5 for Windows软件进行统计分析。结果角膜厚度:A组(515±12.8)μm,B组(526±5.6)μm,C组(505±1.5)μm,D组(495±0.5)μm,E组(487±0.9)μm。A,B组与C,D,E组之间,以及C组与A、B、E组之间的差异有统计学意义(P<0.05);男女差异无统计学意义(P>0.05)。角膜曲率:A组(42.19±0.332)D,B组(43.62±0.266)D,C组(44.25±0.094)D,D组(44.62±0.028)D,E组(45.12±0.050)D。A组与B,C,D,E组之间,以及B组与D、E组之间差异有统计学意义(P<0.05);男女差异无统计学意义(P>0.05)。结论角膜厚度、曲率与年龄显著相关。随着年龄的增长,角膜厚度逐步降低,角膜曲率逐步增加;在低年龄组,角膜厚度和曲率个体之间存在较大差异,40岁之后,这种差异逐步缩小。
OBJECTIVE To learn about the variation on corneal thickness and curvature of different age cataract patients, METHODS Cataract patients of 6 812 cases collected by the Liangjin project in Hainan from June 2009 to June 2010, ruled out corneal ulcer, walleye, keratoconus, corneal trauma, corneal diseases, and divided into five groups according to age: group A 10-20 years(10 cases), group B 20-40 years (49 cases), group C 40-60 years (527 cases), group D 60-80 years (4 709 cases), group E over 80 years (1 517 cases). The Central corneal thick- ness and curvature of each patient was measured, and the statistical parameters analyzed by SPSS 11.5 for Windows software. RESULTS Corneal thickness: group A (515+12.8) μm,group B (526±5.6)μm,group C (505±1.5)μm, group D (495±0.5)μm, group E (487±0.9)μm. There was significant statistical difference between group A, B and C, D, E. Group C and A, B, E also had significant difference (P〈0.05) ; there was no significant difference be- tween male and female in all cases (P〉0.05). Corneal curvature: group A (42.19±0.332)D, group B (43.62±0.266) D, group C (44.25±0.094)D,group D (44.62±0.028)D,group E (45.12±0.050)D. There was significant statistical difference between group A and B, C,D, E. Group B and D, E also had significant difference (P〈0.05) ;there was no significant difference between male and female in all cases (P〉0.05). CONCLUSIONS Positive correlation was found between corneal thickness, curvature and age. With age the corneal thickness gradually decreased and corneal curvature increased; the corneal thickness and curvature of the individual have big differences among the low age group patients, and the difference gradually becomes smaller after the age of 40.
