Objective To determine whether there is a measurable change in hyperopia in children with accommodative esotropia over time.
Methods and analysis A retrospective cohort of children with fully or partially accommodative esotropia diagnosed by age 7 years, followed to age 10 or older, and with at least two cycloplegic refractions, one before age 7 years and one after age 10 years. The annual change was calculated from linear mixed-effect models, overall and during two age periods with subgroup analysis by baseline refractive error (<4D, ≥4D) and type (partial, full) of accommodative esotropia.
Results 405 subjects were studied. Mean age at first and last visit was 3.2 and 12.1 years, respectively, with mean 7.6 cycloplegic refractions. The annual change (95% CI) in refractive error was −0.071 (−0.087 to –0.055) D/yr. Between ages 3 and 7, hyperopia among children with baseline hyperopia <4D increased by 0.12 (0.08 to 0.16) D/yr, while hyperopia among those with baseline 4D or greater was stable (0.0D/yr, −0.03 to 0.04) (p<0.001). Hyperopia decreased from age 7 to 15 years in both subgroups: <4D subgroup −0.17 (−0.20 to –0.14) D/yr, ≥4D subgroup −0.18 (−0.21 to –0.15) D/yr (p=0.58). There was no significant difference in refractive change between fully (n=274) and partially (n=131) accommodative esotropia (p≥0.10).
Conclusion Hyperopia in children with accommodative esotropia is stable or increases up to age 7 years, depending on baseline hyperopia, but decreases gradually between ages 7 and 15 years regardless of baseline refractive error.
