Brief Summary:
This study was designed to compare the difference of using atropine eyedrops alone from atropine combined with the stimulation of auricular acupoints therapy in reducing myopia progression.

Condition or disease Intervention/treatment Phase
Myopia Drug: 0.25 % atropine Drug: 0.5 % atropine Procedure: 0.25 % atropine+auricular acupoints Phase 1

Detailed Description:

A total of 64 school-aged children with myopia, fulfilling eligibility criteria, were recruited. They were randomly assigned to three arms:

  1. 21 treated with the 0.25 % atropine each night (0.25A).
  2. 20 treated with the 0.5 % atropine each night (0.5A).
  3. 23 treated with 0.25 % atropine each night together with stimulation of auricular acupoints(0.25A+E).

This protocol was proceeded for at least 6 months.The differences in post-treatment effects of these three groups were statistically accessed.
