Objective To investigate the correlation between refractive error axial length to corneal radius of curvature among children and adolescents.Methods A total of 3 697 children (7 394 eyes) aged 7 to 12 years old were selected from Low Vision Prevention and Treatment Center in Wuhan during January 2015 to January 2016.Refractive information including diopter,axial length,corneal radius of curvature was collected and analyzed.Results The most common refractive error among 7-12 years old children was mild myopia and hyperopia.The prevalence of myopia and presbyopia was 37.80% and 26.06%,respectively.There were statistical significant differences of axial length between different groups.The children in presbyopia group is shorter than those in myopia group.significant differences of corneal radius of curvature and axial length to corneal radius of curvature in different groups.After controlling for possible covariates,the static refraction increases by 10.01 unit with one unit increase in axial length/corneal radius.Conclusion Axial length to corneal radius of curvature ratio correlates with refraction error,could be a sensitive index for refractive status assessment.
