About this trial

The goal of this interventional study is to compare the efficacy of Atropine 0.05% to Atropine 0.5% treatment against progression of axial length in European children with progressive myopia, and to evaluate the safety, adherence, and reasons for nonresponse. Subjects will use Atropine eye drops for a period of 3 years, followed by a 2 year observational period.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Children aged 6 to ≤ 11 years with bilateral myopia

Disqualifiers

Allergy to atropine or other excipients of the eye drops

History of amblyopia or strabismus

History of retinal dystrophy or systemic disorder

Abnormal ocular biometry aside from axial length
