Popis: Background: Refractive error is the major cause of moderate and severe visual impairment. Visual impairment limits people's ability to perform daily tasks and affects their quality of life. Longitudinal data on the refractive status of the elderly was available only for whites and Africans. The purpose of this study was to report the 7-year incidence of myopia, hyperopia and refractive error change as well as their associated risk factors in a metropolitan elderly Chinese population. Methods: The Shihpai Eye Study 2006 included 460/824 (55.8%) subjects (age range 72–94 years old) of 1361 participants in the 1999 baseline survey for a follow-up eye examination. Incidences were calculated for those who had emmetropia (−0.50D Grade 2 vs. ≤Grade 2) [p Grade 2 vs. ≤Grade 2) (p = 0.02; RR: 1.21; 95% C.I.: 1.02–3.54). Conclusion: In this elderly Asian population, there was on average a slight myopic shift. The incidence of myopia was comparable to population-based studies of other ethnic groups, whereas the incidence of hyperopia was substantially higher.
