Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aims of this clinical trial will test whether or not the onset of nearsightedness is delayed in a group of children randomized to nightly drops in 0.05% atropine in both eyes, in comparison to children who receiving nightly placebo drops in both eyes. The primary outcome is the two-year cumulative incidence of nearsightedness. The second aim of this project will determine whether atropine is associated with slower eye growth in children receiving nightly drops of atropine versus placebo.
