To evaluate central corneal thickness (CCT) in a Japanese population and to describe the relationship between CCT and other factors.
Population-based cross-sectional study.
Reliable CCT measurements were obtained using specular-type pachymetry from 2,868 persons 40 years or older selected randomly from the population of Tajimi City.
The CCT averaged 0.521 +/- 0.032 mm (mean +/- standard deviation). The CCT was thicker in men than in women (P < .001) and was correlated with age (right eyes only), height, weight, diastolic blood pressure, systolic blood pressure (left eyes only), intraocular pressure (IOP), and corneal curvature (P < .05, the Pearson correlation analyses). Multiple regression analysis showed that only gender, IOP, and corneal curvature were significantly (P < .011) associated with CCT.
The mean CCT obtained using an optical method in a Japanese population was 0.521 mm. The CCT was associated significantly with gender, IOP, and corneal curvature but not with age in multiple regression analyses.
评估日本人群的中央角膜厚度（CCT），并描述CCT与其他因素之间的关系。
基于人群的横断面研究。
使用镜面式测厚法对从多治见市人群中随机选取的2868名40岁及以上人群进行可靠的CCT测量。
CCT平均为0.521±0.032毫米（平均值±标准差）。男性的CCT比女性厚（P<.001），并且与年龄（仅右眼）、身高、体重、舒张压、收缩压（仅左眼）、眼压（IOP）和角膜曲率相关（P<.05，Pearson相关分析）。多元回归分析表明，仅性别、IOP和角膜曲率与CCT显著相关（P<.011）。
在日本人群中使用光学方法测得的平均CCT为0.521毫米。在多元回归分析中，CCT与性别、IOP和角膜曲率显著相关，但与年龄无关。
