Study Details

Study Description

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.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Group 1

0.01% atropine

Drug: Atropine
different concentrations (0.01%/0.04%/0.1%) of atropine were administered to high myopic children

Experimental: Group 2

0.04% atropine

Drug: Atropine
different concentrations (0.01%/0.04%/0.1%) of atropine were administered to high myopic children

Experimental: Group 3

0.1% atropine

Drug: Atropine
different concentrations (0.01%/0.04%/0.1%) of atropine were administered to high myopic children

Outcome Measures

Primary Outcome Measures

  1. changes of spherical equivalent [at least 3 years]

    Spherical equivalent as measured by cycloplegia autorefraction

  2. changes of axial length [at least 3 years]

    AL was measured as the distance from the anterior corneal surface to the retinal pigment epithelium (RPE) using IOLMaster or Lenstar
