The Correlation of Myopic Refractive Error and Ocular Components in Primary School Students

Purpose: In this study the correlation among the myopic refractive error and ocular components in primary school students was investigated. Methods: The subjects were 62 children who had no eye diseases. The refractive error, corneal radius, anterior chamber depth, lens thickness, axial length were measured and analysed. Results: Myopic refractive error in primary school students was negatively correlated with the axial length (1~3rd grade r=-0.653, p=0.000/4~6th grade r=-0.742, p=0.000), AL/CR ratio (1~3rd grade r=-0.571, p=0.000/4~6th grade r=-0.852, p=0.000). Conclusions: It was shown that the axial length and axial length(AL)/corneal radius(CR) ratio were very important data for myopic refractive error in primary school students.
