Correlation among the diopter,corneal curvature and axial length in adolescent with ametropia
摘要
Abstract
Objective To investigate the correlation among the corneal curvature,axial length,and diopter in the adolescents with ametropia.Methods Forty three teenagers diagnosed with ametropia (82 eyes) were selected in this study.All participants were divided into the hyperopia (n =21 ,41 eyes)and myopia (n =22,41 eyes)groups according to the spherical equivalent (SE).The diopter,radii of horizontal and ver-tical corneal curvature and axial length were measured and statistically compared between two groups.Results The radii of horizontal and vertical corneal curvature,axial length and axial length/radius of corneal curva-ture significantly differed between two groups (all P <0.05).In both groups,the diopter showed linear corre-lation with the axial length and axial length/radius of corneal curvature (rHyperopia =-0.544 and -0.31 0;rMyopia =-0.558 and 0.790,both P <0.05).Linear correlation was equally observed among the axial length and radii of horizontal and vertical corneal curvature in two groups (rHyperopia =0.572 and 0.668;rMyopia =0.587 and 0.551 ,both P <0.05).The radius of horizontal corneal curvature had linear correlation with that of verti-cal corneal curvature in both groups (rHyperopia =0.937,rMyopia =0.970,both P <0.05).Conclusions In the adolescents with ametropia,the diopter was closely correlated with the corneal curvature and axial length.The axial length was the main factor of the incidence of myopia.The axial length/radius of corneal curvature was a sensitive indicator to monitor myopic progression关键词
