  1. A 2-year longitudinal study of myopia progression and optical component changes among Hong Kong schoolchildren.

    Article - En anglais

    This study investigated refractive error and optical component changes in a group of 142 Hong Kong schoolchildren from age 6 to 17 years over a 2-year period between 1991 and 1993.

    Subjects were refracted subjectively and corneal curvatures and ocular dimensions were measured.

    At the end of the 2-year study, the mean spherical equivalent refraction (SER) was - 1.86 D (SD 1.99 D) and 62% of the schoolchildren were myopic.

    The annual incidence of myopia was 11.8%. Children aged 10 years and under had a greater change in SER toward myopia than older children.

    The annual rate of myopia progression for the myopic children was - 0.46 D (SD 0.40 D) and the rate of progression was greatest between age 6 and 10 years old.

    Vitreous depth/axial length elongation was the main component contributing to the progression of myopia.

    Hong Kong schoolchildren develop myopia as early as 6 years old and myopia progresses at a greater rate compared with children of European extraction.
