目的。关于亚洲老年人屈光状态的流行病学资料很少。本研究的目的是确定台湾大城市华人老年人屈光不正的患病率和相关危险因素。本研究在台北市石牌区进行人口调查。随机选择2045名年龄在65岁及以上的居民，让他们填写一份全面的调查问卷，并进行详细的眼部检查，包括最佳矫正视力和屈光不正测量。其中1361例（66.6%）参加眼科检查。以屈光度(D)计算球面等效（SE），并报道右眼数据。测定经年龄和性别调整的近视（SE < -0.5 D, 19.4%; SE < -1.0 D, 14.59/6）、高度近视（SE < -6.0 D, 2.4%）、远视（SE > +0.5 D, 59.0%; SE > +1.0 D, 44.2%）、散光（柱面< -0.5 D, 74.0%；柱面< -1.0 D, 45.3%）和屈光参差（左右眼SE差> 0.5 D, 45.2%； SE差> 1.0 D, 21.8%）的患病率。近视、散光、屈光参差的发生率随年龄的增长而显著增加（P < 0.01）。远视的患病率随着年龄的增长而下降。除女性的远视发生率（SE > +1.0 D）高于男性（P = 0.004）外，任何类型屈光不正的患病率均无性别差异。多因素回归分析表明，近视与高学历之间的相关性较弱。晶状体核混浊程度与近视率呈正相关，与远视率负相关。中国老年人的近视患病率并不比同样年龄的白人老年人高多少，相比之下，中国年轻人与白人的患病率差异要大得多。这表明不断变化的环境因素可能是中国年轻人群近视患病率增加的原因。
PURPOSE. Few epidemiologic data are available on refractive status in elderly Asians. The purpose of the study was to determine prevalence and risk factors associated with refractive errors in a metropolitan elderly Chinese population in Taiwan.METHODS. A population-based survey was conducted in the Shihpai district of Taipei, Taiwan. A total of 2045 residents aged 65 years or more were randomly selected and invited to complete a comprehensive questionnaire and undertake a detailed ocular examination, including best corrected visual acuity and measurements of refractive error, using autorefraction. Of the subjects, 1361 (66.6%) participated in the ocular examination. Spherical equivalent (SE) was calculated in diopters (D), and data from right eyes were reported.RESULTS. The age- and sex-adjusted prevalence rates were determined for myopia (SE < -0.5 D, 19.4%; SE < -1.0 D, 14.59/6), high myopia (SE < -6.0 D, 2.4%), hyperopia (SE > +0.5 D, 59.0%; SE > +1.0 D, 44.2%), astigmatism (cylinder < -0.5 D, 74.0%; cylinder < -1.0 D, 45.3%), and anisometropia (SE difference between right and left eyes > 0.5 D, 45.2%; SE difference > 1.0 D, 21.8%). The prevalence of myopia, astigmatism, and anisometropia significantly increased with age (all P < 0.01). The prevalence of hyperopia tended to decrease with age. There was no gender difference in prevalence rates in any type of refractive error, except that women had a higher rate of hyperopia (SE > +1.0 D) than men (P = 0.004). Multivariate regression analysis showed that myopia was weakly associated with higher educational level. The severity of lens nuclear opacity was positively associated with the rates of myopia and negatively associated with the rates of hyperopia.Conclusions. The prevalence of myopia in this elderly Chinese population is not much higher than in similarly aged elderly white populations, compared with a much greater difference in prevalence among younger Chinese versus white people. This suggests that changing environmental factors may account for the increased prevalence of myopia in younger cohorts of Chinese.
