The aim of this study was to investigate the anatomical and physiological ocular parameters in adolescents with myopia and to examine the relations between refractive error (SER), ocular biometry, body size and flexibility parameters in myopic adolescents. A cross-sectional study of 184 myopic adolescents, aged 15 to 19 years was conducted. Refractive error and corneal curvature measures of the eye were evaluated using an autorefractometer under cycloplegia. Central corneal thickness was determined by contact pachymetry. The ocular axial length, anterior and vitreous chamber depth, and lens thickness were measured using A-scan biometry ultrasonography. Height and body weight were measured according to a standardized protocol. Body mass index (BMI) was subsequently calculated. Beighton scale was used to measure joint flexibility. Body stature was positively correlated with ocular axial length (r = 0.39, p < 0.001) and vitreous chamber depth (r = 0.37, p < 0.001). There was a negative correlation between height and SER (r = − 0.46; p < 0.001). Beighton score and body weight had weak positive correlations with axial length and vitreous chamber depth, and a weak negative correlation with SER. A significantly more negative SER was observed in the increased joint mobility group (p < 0.05; U = 5065.5) as compared to normal joint mobility group: mean − 4.37 ± 1.85 D (median − 4.25; IQR − 6.25 to − 3.25 D) and mean − 3.72 ± 1.66 D (median − 3.50; IQR − 4.75 to − 2.25 D) respectively. There was a strong association between height and axial length, as well as SER. Higher degree of myopia significantly correlated with greater Beighton score (increased joint mobility).

本研究的目的是调查近视青少年的眼部解剖和生理参数，并探讨近视青少年屈光不正（SER）、眼部生物测量、身体尺寸和灵活性参数之间的关系。对 184 名 15 至 19 岁近视青少年进行了横断面研究。在睫状肌麻痹下使用自动验光仪评估眼睛的屈光不正和角膜曲率测量。中央角膜厚度通过接触测厚法测定。使用 A 扫描生物测量超声检查测量眼轴长度、前房和玻璃体房深度以及晶状体厚度。根据标准化方案测量身高和体重。随后计算体重指数（BMI）。 Beighton 量表用于测量关节灵活性。身高与眼轴长度（r = 0.39， p < 0.001）和玻璃体腔深度（r = 0.37， p < 0.001）呈正相关。身高和 SER 之间存在负相关（r = − 0.46； p < 0.001）。 Beighton评分和体重与眼轴长度和玻璃体腔深度呈弱正相关，与SER呈弱负相关。与正常关节活动组相比，关节活动度增加组的负 SER 显着增加（ p < 0.05；U = 5065.5）：平均值 − 4.37 ± 1.85 D（中位数 − 4.25；IQR − 6.25 至 − 3.25 D）平均值 - 3.72 ± 1.66 D（中位数 - 3.50；IQR - 4.75 至 - 2.25 D）。身高和眼轴长度以及 SER 之间存在很强的相关性。近视度数越高，Beighton 评分越高（关节活动度增加）显着相关。
