PurposeTo investigate variables associated with myopic progression despite treatment in the Atropine in the Treatment of Myopia Study.DesignRetrospective cohort study.MethodsTwo hundred of 400 children were randomized to receive atropine 1% in 1 eye only in this institutional study. Children were followed up with cycloplegic autorefraction every 4 months over 2 years. Children whose myopia progressed by more than 0.5 diopter (D) in the atropine-treated eye at 1 year were classified as being progressors.ResultsAmong the 182 children still in the study at 1 year, 22 (12.1%) were classified as progressors. Univariate analysis suggested these children tended to be younger (8.5 ± 1.4 years vs 9.3 ± 1.5 years; P = .023), to have higher myopic spherical equivalent (SE) at baseline (−3.6 ± 1.3 D vs −2.8 ± 1.4 D; P = .015), and to have 2 myopic parents (77.3% vs 48.1%; P = .012). In nonprogressors, the myopia progression at 1 year was less in the atropine-treated eyes compared with the untreated fellow eye (+0.16 ± 0.37 D vs −0.73 ± 0.48 D; P < .001), but in progressors, progression was more similar between eyes (−0.92 ± 0.31 D vs −1.06 ± 0.44 D; P = .363). Regression analysis showed that the risk of being a progressor was 40% lower with each year of increased age, 43% lower for every 1.0 D less in myopia at baseline, and 59% lower for every 1.0 D less in myopic change in the untreated eyes over the first year.ConclusionsDoctors and parents need to be aware that there is a small group of children (younger, with higher myopia, and greater tendency of myopic progression) who may still progress while receiving atropine treatment.
