| Abstract | Purpose: To quantify the defocus characteristics in the near-work environment at home and investigate the relationship with subsequent myopia progression. Methods: Fifty subjects (aged 7-12 years) were recruited and followed for 1 year. The home near-work environment (writing desk) was measured at a baseline home-visit using the Kinect-for-Windows to capture a 3-dimensional image. The depth values of the image were then converted into scene defocus with respect to the subject's viewpoint. The defocus characteristics were quantified as the dioptric volume (the total amount of net defocus, or DV) and standard deviation of the defocus values (SD Results: The baseline spherical equivalent refraction (M) and refraction change over 1 year (∆M) were - 1.51 ± 2.02 D and - 0.56 ± 0.45 D respectively. DV was not significantly correlated with ∆M (Spearman's ρ = -0.25, p = 0.08), while SD Conclusion: The defocus profile in the home environment within the para-central field of view is associated with childhood refractive error development. |
