Pharmacological and Non-pharmacological Treatment Effects on Children With Different Predicted Myopia Progression Rate

Subjective refraction,Axial length

The goal of this clinical trial is to compare pharmacological and non-pharmacological
 treatment effects on the children with different predicted myopia progression rate measured
 by modified multifocal electroretinogram. The main questions it aims to answer are:
 
 - the effectiveness of using 0.05% atropine and prescribing DIMS lens for myopia control
 in children with different myopia progression rates
 
 - the contribution of L/M cones in juvenile myopia progression and changes of retinal
 activities under atropine and DIMS treatment.
 
 Participants will have baseline and follow-up eye examinations and given either
 pharmacological treatment with 0.05% atropine or non-pharmacological treatment with DIMS lens
 for myopia control.
 
 Researchers will compare the changes of refractive errors and axial length after different
 types of interventions and investigate the relations between the parameters of mfERG
 responses and the thicknesses of retinal layers and choroid.
