Objective  To investigate the status of refractive development among children and ado-lescents aged 6-16 in Fuzhou. 

Method  From January 1 to December 31, 2021, we collected data on children and adolescents aged 6-16 years in Fuzhou, which included spherical equivalent (SE) after cycloplegia, axial length (AL), corneal radius (CR) and calculated the AL/CR ratio, and performed correlation analysis. 

Results  A total of 2,888 patients were included, and the right eye was used for all analyses. The differences in SE after cy-cloplegia, AL and the AL/CR ratio in different age groups were statistically significant (P<0.001). There was a negative correlation between SE after cycloplegia and age (r=-0.356, P<0.01), and a positive correlation between AL, AL/CR ratio and age (r=0.413, P<0.01; r=0.425, P<0.01). CR remained stable with age, and there was no sig-nificant correlation between CR and age (r=0.035, P>0.05). There were significant differences in AL, CR and AL/CR ratio between different genders (P<0.001), females had shorter AL, smaller CR, steeper corneal curvature, and slightly lower AL/CR ratio than males. The differences in AL and AL/CR ratio between different refractive state groups were statistically significant (P<0.001), AL and AL/CR ratio were positively correlated with the de-gree of myopia (r=0.636, P<0.01; r=0.767, P<0.01). There was no statistical significance for the difference in CR between different refractive state groups (P>0.05), but there were statistically significant differences in CR be-tween different myopia groups (P<0.001), CR was negatively correlated with the degree of myopia (r=-0.067, P<0.01), CR in the high myopia group was smaller than that in the moderate  and low myopia groups, i.e. the corneal curvature was steeper. 

Conclusion  The refractive status of children and adolescents aged 6-16 years in Fuzhou, drifted towards myopia with increasing age, AL and the AL/CR ratio showed an increasing trend, while the CR remained basically stable.
