Brief Summary
Objective: to evaluate the efficacy of different concentrations of atropine eye drops in controlling the progression (diopter, axial length) of high myopia in young children, and to compare the compliance, adverse reaction and regression rate of different concentrations of atropine eye drops in myopia control. Intervention: Group 1 (0.01% atropine group), Group 2 (0.04% atropine group), Group 3 (0.1% atropine group). During the 2-year intervention period after entering the group, each concentration of atropine eye drops were given every night at a fixed time before going to bed, one drop each time, implemented by parents (supervision), and the wechat small program was completed.
