To determine normal exophthalmometric values for a Sri Lankan population and investigate their demographic, physical, refractive and ocular biometric correlates.
The Kandy Eye study was a population-based, cross-sectional study. By randomized cluster sampling, 1721 eligible participants, who were 40 years old and over were identified; 1375 participated. Exophthalmometry was performed with Hertel's exophthalmometer. Participants' demographics including age, gender and ethnicity were recorded. Height, weight, body mass index, non-cycloplegic refraction and ocular biometry were measured with standardized methods. Summary statistical analysis was performed for exophthalmometric values and relationships with other factors were tested using Pearson product-moment correlation coefficient analysis, standard single and multiple linear regression analysis.
A total of 1341 subjects were included in the analysis. Exophthalmometric values for the population had a mean of 15.82 mm, standard deviation of 2.73 mm and range of 10.46-21.28 mm. Exophthalmometric values for men were significantly higher than women. There were no significant differences between the racial groups' exophthalmometric values (Sinhalese, Tamils, Moors). Exophthalmometric values were significantly correlated with age, gender, height, weight, body mass index, base and axial length but not to refractive spherical equivalents. Only gender, weight, base and axial length were independent predictors for exophthalmometric values after adjusting for confounders.
In this Sri Lankan population, our study provided the first reported estimates of a normal exophthalmometric range and determined gender, weight, base and axial length as its correlates. Sri Lankans are the first population to demonstrate this relationship between weight and exophthalmometric values and also showed that refraction is not a cause for pseudo-proptosis.
确定斯里兰卡人群的正常眼球突出测量值，并研究其与人口统计学、身体特征、屈光和眼部生物特征的相关性。
康提眼研究是一项基于人群的横断面研究。通过随机整群抽样，确定了1721名40岁及以上的符合条件的参与者；1375人参与。使用Hertel眼球突出计进行眼球突出测量。记录参与者的人口统计学信息，包括年龄、性别和种族。采用标准化方法测量身高、体重、体重指数、非散瞳验光和眼部生物测量。对眼球突出测量值进行汇总统计分析，并使用Pearson积矩相关系数分析、标准单因素和多因素线性回归分析检验与其他因素的关系。
共有1341名受试者纳入分析。该人群的眼球突出测量值平均为15.82mm，标准差为2.73mm，范围为10.46 - 21.28mm。男性的眼球突出测量值显著高于女性。不同种族群体（僧伽罗人、泰米尔人、摩尔人）的眼球突出测量值之间无显著差异。眼球突出测量值与年龄、性别、身高、体重、体重指数、眼轴长度和眼轴相关，但与等效球镜度无关。调整混杂因素后，只有性别、体重、眼轴长度和眼轴是眼球突出测量值的独立预测因素。
在这个斯里兰卡人群中，我们的研究首次报告了正常眼球突出测量范围，并确定性别、体重、眼轴长度和眼轴为其相关因素。斯里兰卡人是首个证明体重与眼球突出测量值之间存在这种关系的人群，同时也表明屈光不正不是假性眼球突出的原因。
