目的.描述马来成年城市人群屈光不正的患病率和危险因素。这项基于人群的横断面研究在新加坡的3280名40至80岁的马来成年人中进行。所有人都在一个集中的诊所进行检查，并进行标准化的采访和评估屈光不正和提出和最佳矫正视力。通过使用最小分辨率角（logMAR）数字图表的对数在4 m的距离处测量单眼的距离视力，参与者佩戴“步入式”光学矫正（眼镜或隐形眼镜）（如果有的话）。由经过培训、认证的研究验光师通过主观验光确定屈光度。使用与用于呈现视力相同的测试方案，对最佳矫正视力进行单眼评估，并记录为logMAR评分。屈光不正定义为最佳矫正视力与较佳眼的当前视力相比至少改善0.2 logMAR（2行等效）。我们研究中受试者的平均年龄为58 ± 11岁，52%的受试者为女性。在我们的研究中，新加坡马来成年人（n = 3115）屈光不正的患病率为20.4%（年龄标准化患病率为18.3%）。女性屈光不正欠矫率高于男性（21.8%比18.8%，P = 0.04）。50岁以上的受试者屈光不正欠矫率也高于40 - 49岁的受试者（22.6% vs. 14.3%，P < 0.001）。不戴眼镜者比戴眼镜者更容易出现屈光不正（24.4%比14.4%，P < 0.001）。小学及以下学历者屈光不正的发生率是中学及以上学历者的1.89倍（P = 0.03）。相比之下，有眼病史的人屈光不正的可能性低0.74倍（P = 0.003）。新加坡马来人屈光不正患者中屈光不正欠矫的比例高于新加坡华人。屈光不正矫正不足是新加坡马来成年人可矫正视力障碍的一个重要原因，影响到五分之一的人。（Invest Ophthalmol维斯科学。2009;50：3621-3628）DOI：10.1167/iovs.08-2788
PURPOSE. To describe the prevalence and the risk factors of undercorrected refractive error in an adult urban Malay population.METHODS. This population-based, cross-sectional study was conducted in Singapore in 3280 Malay adults, aged 40 to 80 years. All individuals were examined at a centralized clinic and underwent standardized interviews and assessment of refractive errors and presenting and best corrected visual acuities. Distance presenting visual acuity was monocularly measured by using a logarithm of the minimum angle of resolution (logMAR) number chart at a distance of 4 m, with the participants wearing their "walk-in" optical corrections (spectacles or contact lenses), if any. Refraction was determined by subjective refraction by trained, certified study optometrists. Best corrected visual acuity was monocularly assessed and recorded in logMAR scores using the same test protocol as was used for presenting visual acuity. Undercorrected refractive error was defined as an improvement of at least 0.2 logMAR (2 lines equivalent) in the best corrected visual acuity compared with the presenting visual acuity in the better eye.RESULTS. The mean age of the subjects included in our study was 58 +/- 11 years, and 52% of the subjects were women. The prevalence rate of undercorrected refractive error among Singaporean Malay adults in our study (n = 3115) was 20.4% (age-standardized prevalence rate, 18.3%). More of the women had undercorrected refractive error than the men (21.8% vs. 18.8%, P = 0.04). Undercorrected refractive error was also more common in subjects older than 50 years than in subjects aged 40 to 49 years (22.6% vs. 14.3%, P < 0.001). Nonspectacle wearers were more likely to have undercorrected refractive errors than were spectacle wearers (24.4% vs. 14.4%, P < 0.001). Persons with primary school education or less were 1.89 times (P = 0.03) more likely to have undercorrected refractive errors than those with post-secondary school education or higher. In contrast, persons with a history of eye disease were 0.74 times (P = 0.003) less likely to have undercorrected refractive errors. The proportion of undercorrected refractive error among the Singaporean Malay adults with refractive errors was higher than that of the Singaporean Chinese adults with refractive errors.CONCLUSIONS. Undercorrected refractive error is a significant cause of correctable visual impairment among Singaporean Malay adults, affecting one in five persons.
