Background: A rebound in myopia progression following cessation of atropine eyedrops has been reported, yet there is limited data on the effects of stopping 0.01% atropine compared to placebo control. This study tested the hypothesis that there is minimal rebound myopia progression after cessation of 0.01% atropine eyedrops, compared to a placebo. Methods: Children with myopia (n = 153) were randomised to receive 0.01% atropine eyedrops or a placebo (2:1 ratio) daily at bedtime during the 2‐year treatment phase of the study. In the third year (wash‐out phase), all participants ceased eyedrop instillation. Participants underwent an eye examination every 6 months, including measurements of spherical equivalent (SphE) after cycloplegia and axial length (AL). Changes in the SphE and AL during the wash‐out phase and throughout the 3 years of the study (treatment + wash‐out phase) were compared between the treatment and control groups. Results: During the 1‐year wash‐out phase, SphE and AL progressed by −0.41D (95% CI = −0.33 to −0.22) and +0.20 mm (95% CI = −0.46 to −0.36) in the treatment group compared to −0.28D (95% CI = 0.11 to 0.16) and +0.13 mm (95% CI = 0.18 to 0.21) in the control group. Progression in the treatment group was significantly faster than in the control group (p = 0.016 for SphE and <0.001 for AL). Over the 3‐year study period, the cumulative myopia progression was similar between the atropine and the control groups. Conclusions: These findings showed evidence of rapid myopia progression following cessation of 0.01% atropine. Further investigations are warranted to ascertain the long‐term effects of atropine eyedrops. [ABSTRACT FROM AUTHOR]
