Analysis of related parameters of ocular biometric values in children and adolescents

Abstract

AIM: To measure ocular biometric values with sexual and age and determine the relationship between the differences using the Lenstar 900. METHODS: Totally 413 myopes 826 eyes, 200 males(400 eyes)and 213 females(426 eyes), were enrolled in this study and were divided into 3 groups: Group Ⅰ(10 years). Central corneal thickness(CCT), anterior chamber depth(ACD), lens thickness(LT), axial length(AL), white-to-white distance(WWD)and pupil diameter(PD)were measured by Lenstar 900. The differences between age groups and gender groups were compared using the LSD and SNKk methods in variance analysis. Pearson correlation coefficient to assess AL, CCT, ACD, LT, WWD, PD in children and adolescents. RESULTS: There were significant difference in CCT between ages groups(Pr=0.208, 0.167; Pr=0.620, 0.238, 0.192; Pr=-0.271, -0.186, -0.227; Pr=0.273, PCONCLUSION:CCT has gradually thickening trend with ages. Men are more than women in ACD and AL. CCT shows positive correlation with WWD and PD and ACD shows positive correlation with AL, WWD, PD. LT shows negative correlation with ACD, AL and WWD. WWD showed positive correlation with PD.
