Purpose To assess the effect of weekly 1% atropine use on children’s myopia progression and whether the effect is sustainable. Methods Medical records of myopic children aged 3–15 years receiving weekly 1% atropine for more than 1 year were retrospectively reviewed. Axial length (AL) and spherical equivalent refraction (SER) at every visit were collected. The changes in AL or SER over time were analysed using generalised estimating equation. The related factors of myopic progression were performed by multiple linear regression. The performance of short-term AL change to predict atropine-poor responders (AL change >0.2 mm/year) was assessed using receiver operating characteristic analysis. Results A total of 694 participants with a mean age of 8.83 years were included. The participants with follow-up time reached 1, 2, 3 and 4 years were 256 (36.9%), 250 (36.0%), 143 (20.6%) and 45 (6.5%) separately. The cumulative change in AL was 0.05 mm, 0.24 mm, 0.47 mm, 0.56 mm separately for 1-year, 2-year, 3-year and 4- year treatment. Approximate 0.20 mm elongation per year was observed since the second-year of the treatment. Older age and lower initial myopic refraction were independently associated with less myopic progression. A decrease in AL of more than 0.04 mm during the initial 2 months could serve as an indicator for identifying fast progressors (AL change >0.2 mm/year) over a 2-year period, with sensitivity and specificity rates of 0.78 and 0.73, respectively. Conclusion Weekly 1% atropine may be a potentially effective treatment with longer lasting effects for children with myopia control especially in those with older age and lower myopia.
