Studying ocular biometric parameters in different populations and determining the relationship with personal characteristics can provide valuable information about ocular growth and help provide a better understanding of refractive errors.
To describe distributions of ocular biometry and to evaluate its associations with age, gender, spheric equivalent in Turkish children.
In this prospective study 344 children aged 3-14 years were evaluated. Parameters studied included axial length (AL), anterior chamber depth (ACD), and mean corneal radius (CR) measured with optical biometry. Cycloplegic refraction values were obtained using autorefractometer. The change of biometric parameters according to age and gender were evaluated. The relationship between ocular biometry parameters with refraction and age was analyzed by linear regression.
Mean spherical equivalent (SE), AL, ACD and AL/CR observed to be lowest in the preschooler group (P < 0.001). SE reduced with age, and a weak correlation observed between SE and age (r = -0.333). AL and ACD had moderate and weak positive correlations with age respectively (r = 0.511; r = 0.304). There were negative correlations between SE with AL, ACD and AL/CR (r = -0.826; r = -0.540; r = -0.886). The strongest correlation with SE among these parameters was identified for AL/CR. AL and ACD were higher in boys, while the CR was lower in girls (p < 0.001).
While AL in children in late schooler group is higher than European countries, it shows similar characteristics in early schooler group. In addition AL is lower in all age groups than Asian population sexcept preschooler group. With age AL increases, SE decreases and AL plays a key role in refractive development.
研究不同人群的眼部生物测量参数，并确定其与个体特征的关系，可以提供有关眼球生长的有价值信息，并有助于更好地了解屈光不正。
描述土耳其儿童的眼部生物测量参数分布，并评估其与年龄、性别、等效球镜的关系。
本前瞻性研究共评估了 344 名 3-14 岁的儿童。研究的参数包括使用光学生物测量仪测量的眼轴长度（AL）、前房深度（ACD）和平均角膜半径（CR）。使用自动屈光仪获得睫状肌麻痹下的屈光度。评估了生物测量参数随年龄和性别变化的情况。通过线性回归分析了眼部生物测量参数与屈光不正和年龄的关系。
平均等效球镜（SE）、AL、ACD 和 AL/CR 在学龄前儿童组中最低（P<0.001）。SE 随年龄而降低，SE 与年龄之间存在弱相关性（r=-0.333）。AL 和 ACD 与年龄呈中度和弱正相关（r=0.511；r=0.304）。SE 与 AL、ACD 和 AL/CR 呈负相关（r=-0.826；r=-0.540；r=-0.886）。这些参数中与 SE 相关性最强的是 AL/CR。男孩的 AL 和 ACD 较高，而女孩的 CR 较低（p<0.001）。
虽然学龄后期儿童的 AL 高于欧洲国家，但在学龄前期儿童中具有相似的特征。此外，除学龄前儿童组外，所有年龄组的 AL 均低于亚洲人群。随着年龄的增长，AL 增加，SE 降低，AL 在屈光发育中起着关键作用。
