PurposeTo examine the possible factors related to the progression of myopia in Singapore children.MethodsOne hundred fifty-three Singapore children aged 6 to 12 years were recruited to participate in a concurrent cohort study of the risk factors for the progression of myopia. Socioeconomic status, outdoor activity, and near-work activity were documented in a face-to-face clinic interview. The changes in cycloplegic subjective refraction and autorefraction were ascertained with the use of a Nidek ARK 900 over a 2-year period.ResultsThe average rate of progression of myopia as measured by subjective refraction was −0.59 D per year (95% confidence interval −0.52, −0.66). Younger children and children who were more myopic at the beginning (refractive error worse than −2.0 D) of the study had higher myopia progression rates.ConclusionsMyopia progression was faster for younger children and for children who had more severe myopia at baseline. Socioeconomic status and near-work activity were not related to myopia progression.
