Abstract：
BACKGROUND: The purpose of this study was to quantify how much of the burden of visual impairment (VI) and unmet need in Talagang, identified by Rapid Assessment of Avoidable Blindness (RAAB) survey data, has been addressed by Community Eye Health (CEH) programme efforts.
METHODS: A RAAB survey was carried out in November 2018, with 2,824 participants in Talagang Tehsil, Punjab, Pakistan, aged 50 and over. Census data were used to extrapolate survey data to the population. Alongside this, a CEH programme was launched, consisting of community eye screening, and onward referral to rural health centres, secondary or tertiary ophthalmological services, as required. This health intervention aimed to address the eye care needs surfaced by the initial survey. From 2018 to 2022, 30,383 people aged 50 or over were screened; 14,054 needed referral to further steps of the treatment pathway and more detailed data collection. Programme data were compared to estimates of population unmet needs. Main outcome measures were prevalence of VI, and proportion of need met by CEH Programme, by cause and level of VI.
RESULTS: Among those aged 50 and over, 51.0% had VI in at least one eye. The leading causes were cataract (46.2%) and uncorrected refractive error (URE) (25.0%). In its first four years, the programme reached an estimated 18.3% of the unmet need from cataract, and 21.1% of URE, equally in both men and women.
CONCLUSIONS: Robustly collected survey and programme data can improve eye health planning, monitoring and evaluation, address inequities, and quantify the resources required for improving eye health. This study quantifies the time required to reach eye health needs at the community level.

摘要：
背景：这项研究的目的是量化Talagang的视力障碍（VI）负担和未满足的需求，由可避免失明快速评估(RAAB)调查数据确定，已通过社区眼健康(CEH)计划努力解决。
方法：2018年11月进行了RAAB调查，在TalagangTehsil有2,824名参与者，旁遮普,巴基斯坦,50岁及以上。人口普查数据用于将调查数据外推至人群。除此之外,启动了一项CEH方案，包括社区眼部筛查，并继续转诊到农村卫生中心，二级或三级眼科服务，根据需要。这项健康干预措施旨在解决最初调查所提出的眼部护理需求。从2018年到2022年，对30,383名50岁或以上的人进行了筛查；14,054人需要转介治疗途径的进一步步骤和更详细的数据收集。将方案数据与未满足人口需求的估计数进行了比较。主要结果指标是VI的患病率，以及CEH计划满足的需求比例，根据VI的原因和水平。
结果：在50岁及以上的人群中，51.0%在至少一只眼睛中具有VI。主要原因是白内障（46.2％）和未矫正的屈光不正（URE）（25.0％）。在最初的四年里，该计划达到了白内障未满足需求的18.3％，和21.1%的URE，男人和女人都一样。
结论：大量收集调查和计划数据可以改善眼健康规划，监测和评估，解决不平等问题，并量化改善眼睛健康所需的资源。这项研究量化了在社区层面达到眼睛健康需求所需的时间。
