目的.评估孟加拉国未矫正屈光不正的程度和相关因素，并提出满足这一需求的方法。选择了12,782名成年人（大于或等于30岁）的全国代表性样本。其中，11，624例受试者接受了人口统计学访谈、视力（最小分辨角的对数[logMAR]）测量、自动验光和视盘检查。任何一只眼睛的视力低于6/12的受试者还进行了矫正屈光测量、白内障分级和散瞳视网膜检查。在接受检查的11，624名受试者中，2，469名（22.1%）为近视（小于-0.5 D），2，308名（20.6%）为远视（大于+0.5 D）。使用6/12和6/18的视力临界值，按[满足需求/（满足需求+未满足需求）X 100%]计算的眼镜覆盖率分别为25.2%和40.5%，男性和城市居民的眼镜覆盖率较高。年龄较大的受试者和受过良好教育的受试者更有可能戴眼镜;然而，大多数眼镜佩戴者（81%）的矫正不足。在1142例将从眼镜中获益的受试者中，827例（72.4%）适合使用现成眼镜。不戴眼镜的受试者中较好眼睛的视力低于6/12（n = 835），矫正后将达到6/12或更好（未满足的需求）。外推到全国人口中估计有150万（6.7%）成年男性和180万（9.2%）女性的屈光矫正需求未得到满足。在孟加拉国，奇观覆盖率低，需求大量未得到满足。这项调查确定了风险群体，特别是妇女和农村地区的人。对屈光服务的可用性的描述提出了需要改进的领域（例如，这些项目可能使孟加拉国能够实现世界卫生组织2020年愿景倡议的目标。
PURPOSE. To assess the extent of uncorrected refractive error and associated factors in Bangladesh and to suggest ways in which this need can be met.METHODS. A nationally representative sample of,12,782 adults (greater than or equal to30 years of age) was selected. Of them, 11,624 subjects underwent a demographic interview, visual acuity (logarithm of the minimum angle of resolution [logMAR]) measurement, automated refraction, and optic disc examination. Subjects with visual acuity less than 6/12 in either eye also had a corrected refraction measurement, cataract grading, and dilated retinal examination.RESULTS. Of the 11,624 subjects examined, 2,469 (22.1%) were myopes (less than -0.5 D) and 2,308 (20.6%) hyperopes (more than +0.5 D). The spectacle coverage percentage, calculated as [met need/(met need + unmet need) X 100%] was 25.2% and 40.5%, using 6/12 and 6/18 visual acuity cutoffs, respectively, and was higher in men and urban inhabitants. Older subjects and the literate and more highly educated were more likely to wear spectacles; however, most spectacle wearers (81%) had inadequate correction. Of the 1142 subjects who would benefit from spectacles, 827 (72.4%) would be suitable for off-the-shelf spectacles. Subjects without spectacles with less than 6/12 in the better eye (n = 835), would achieve 6/12 or better with correction (unmet need). Extrapolation to the national population yields an estimate that 1.5 million (6.7%) adult men and 1.8 million (9.2%) women have an unmet need for refractive correction.CONCLUSIONS. In Bangladesh, there is low spectacle coverage with a large unmet need. This survey identified risk groups, in particular women and those living in rural areas. This description of the availability of refractive services suggests areas for improvement (e.g., off-the-shelf spectacles) that may enable Bangladesh to achieve the goals of the World Health Organization's Vision 2020 initiative.
