Study type：

Interventional study 

研究所处阶段：

I期临床试验 

Study phase：

1 

研究目的：

To evaluate the efficacy and safety of low-dose atropine compared to placebo in the Indian population and also to study the impact of various modifiable and non-modifiable factors on myopia progression (MP) and drug efficacy (DE). 

Objectives of Study：

To evaluate the efficacy and safety of low-dose atropine compared to placebo in the Indian population and also to study the impact of various modifiable and non-modifiable factors on myopia progression (MP) and drug efficacy (DE). 

药物成份或治疗方案详述：

It was a single-center prospective placebo-controlled interventional study. 43 participants aged 6-16 years with progressive myopia received 0.01% atropine in the right eyes (treatment) and placebo in the left eyes (control) for 1-year. The main outcome measures were annual MP and axial length elongation (ALE) in treatment and control eyes and their percentage difference between two eyes (DE). Secondary outcome measures were the occurrence of any adverse events and the correlation of MP, ALE, and DE with various factors.

纳入标准：

Clinical records of myopic children who underwent cycloplegic refraction at the institution in the past one year were screened and children aged 6-16 years with myopia ranging from -1 D to -7 D (spherical equivalent) in both eyes, progression equal or greater than 0.5 D in the preceding year, stable astigmatism of 1.5 D or less, anisometropia of 2 D or less, and best-corrected visual acuity at least 6/9 were enrolled in the study (selection and enrolment of the children being done until 31st October 2018).  

Inclusion criteria

Clinical records of myopic children who underwent cycloplegic refraction at the institution in the past one year were screened and children aged 6-16 years with myopia ranging from -1 D to -7 D (spherical equivalent) in both eyes, progression equal or greater than 0.5 D in the preceding year, stable astigmatism of 1.5 D or less, anisometropia of 2 D or less, and best-corrected visual acuity at least 6/9 were enrolled in the study (selection and enrolment of the children being done until 31st October 2018).  

排除标准：

Patients with ocular pathology like spherophakia, retinal dystrophies, corneal dystrophy or other diseases, manifest strabismus, allergy to atropine eye drops, or children who were already under treatment for myopia control were excluded.
