Abstract

PURPOSE: To assess the additive potency of low-dose atropine combined with optical measures designed to decrease myopia progression. MATERIALS AND METHODS: This retrospective study included 104 myopic children aged 5-12 over 4 years, divided into five groups: daily instillation of 0.01% atropine and distance single-vision spectacles (A), 0.01% atropine and progressive addition lenses (A + PAL), 0.01% atropine and soft contact lens with peripheral blur (A + CL). Two control groups were included, prescribed bifocal spectacles or single vision (SV) spectacles. Cycloplegic spherical equivalence refraction was measured biannually, including 1 year after cessation of treatment. RESULTS: A significant decrease in myopia progression was noted during the 2 nd and 3 rd years of atropine treatment: A -0.55 ± 0.55D, -0.15 ± 0.15, -0.12 ± 0.12D were 1 st, 2 nd, 3 rd years, respectively, A + PAL -0.47 ± 0.37D, -0.10 ± 0.25D, and -0.11 ± 0.25D were 1 st, 2 nd, 3 rd years, respectively, A + CL -0.36 ± 0.43D, -0.13 ± 0.29D, and -0.10 ± 0.27D were 1 st, 2 nd, 3 rd years, respectively. Myopia progression over 3 years, respectively, was -0.82 ± 0.50D, -0.70 ± 0.69D, -0.59 ± 0.66D in the bifocal group and -1.20 ± 1.28D, -0.72 ± 0.62D, -0.65 ± 0.47D in the SV group. One year after cessation of atropine treatment, myopia progression was - 0.32 ± 0.31D in A, -0.23 ± 0.28D in A + PAL, and -0.18 ± 0.35D in A + CL. CONCLUSION: Atropine 0.01% presented as effective at decelerating myopia progression, more prominent in the 2 nd and 3 rd years of treatment. Combining atropine 0.01% with optical modalities exhibited a trend for added efficacy over monotherapy. A + CL exhibited the least rebound effect 1 year after cessation of treatment.
