Purpose: To examine the possible factors related to the progression of myopia in Singapore children Methods: One hundred fifty-three Singapore children aged 6 to 12 years were recruited to participate in a concurrer 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. Results: The average rate of progression of myopia as measured by subjective refraction was -0.59 D per year (95% confidence interval -0.52 to -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. Conclusions: Myopia 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.
