Eye health is essential to achieve the Sustainable Development Goals; vision needs to be reframed as a development issue There is extensive evidence showing that improving eye health contributes directly and indirectly to achieving many Sustainable Development Goals, including reducing poverty and improving work productivity, general and mental health, and education and equity. Improving eye health is a practical and cost-effective way of unlocking human potential. Eye health needs to be reframed as an enabling, cross-cutting issue within the sustainable development framework. Almost everyone will experience impaired vision or an eye condition during their lifetime and require eye care services; urgent action is necessary to meet the rapidly growing eye health need In 2020, 1•1 billion people had distance vision impairment or uncorrected presbyopia. By 2050, this figure is expected to rise to 1•8 billion. Most affected people live in low-income and middle-income countries (LMICs) with avoidable causes of vision impairment. During the life course, most people will experience vision impairment, even if just the need for reading glasses. Because of unmet needs and an ageing global population, eye health is a major public health and sustainable development concern which warrants urgent political action. Eye health is an essential component of universal health coverage; it must be included in planning, resourcing, and delivery of health care Universal health coverage is not universal without affordable, high quality, equitable eye care. In line with the WHO World report on vision, we urge countries to consider eye care as an essential service within universal health coverage. To deliver comprehensive services including promotion, prevention, treatment, and rehabilitation, eye care needs to be included in national strategic health plans and development policies, health financing structures, and health workforce planning. Coordinated intersectoral action is needed to systematically improve population eye health, also within healthy ageing initiatives, schools, and the workplace. Integration of eye health services with multiple relevant components of health service delivery and at all levels of the health system is of central importance.

Purpose: To complete the baseline trachoma map worldwide by conducting population-based surveys in an estimated 1238 suspected endemic districts of 34 countries. Methods: A series of national and sub-national projects owned, managed and staffed by ministries of health, conduct house-to-house cluster random sample surveys in evaluation units, which generally correspond to “health district” size: populations of 100,000–250,000 people. In each evaluation unit, we invite all residents aged 1 year and older from h households in each of c clusters to be examined for clinical signs of trachoma, where h is the number of households that can be seen by 1 team in 1 day, and the product h × c is calculated to facilitate recruitment of 1019 children aged 1–9 years. In addition to individual-level demographic and clinical data, household-level water, sanitation and hygiene data are entered into the purpose-built LINKS application on Android smartphones, transmitted to the Cloud, and cleaned, analyzed and ministry-of-health-approved via a secure web-based portal. The main outcome measures are the evaluation unit-level prevalence of follicular trachoma in children aged 1–9 years, prevalence of trachomatous trichiasis in adults aged 15 + years, percentage of households using safe methods for disposal of human feces, and percentage of households with proximate access to water for personal hygiene purposes. Results: In the first year of fieldwork, 347 field teams commenced work in 21 projects in 7 countries. Conclusion: With an approach that is innovative in design and scale, we aim to complete baseline mapping of trachoma throughout the world in 2015.

Background.Interventions to reduce under-5 mortality can either target the vulnerable or include all children regardless of state of health. Here, we assess whether mass distribution of a broad-spectrum antibiotic to pre-school children reduces mortality in sub-Saharan Africa.Methods.MORDOR was a large simple trial that randomized communities in Malawi, Niger, and Tanzania to 4 biannual mass distributions of either oral azithromycin or placebo. Children aged 1-59 months were enumerated and offered treatment. Vital status was assessed at the subsequent biannual census. The primary outcome was aggregate all-cause mortality, with country-specific rates as pre-specified subgroup analyses.Results.In total, 1533 communities were randomized, 190,238 children censused at baseline, and 323,302 person-years monitored. Mean antibiotic coverage over the 4 biannual distributions was 90.4% (SD 10.4%) of the censused population. The overall annual mortality rate in placebo- treated communities was 16.5 per 1000 person-years (9.6 per 1000 person-years in Malawi, 27.5 in Niger, and 5.5 in Tanzania). Antibiotic-treated communities had an estimated 13.5% lower mortality overall (95% CI 6.7%—19.8%, P<0.001). Mortality was 5.7% lower in Malawi (CI - 9.7%—18.9%, P=0.45), 18.1% lower in Niger (CI 10.0%—25.5%, P<0.001), and 3.4% lower in Tanzania (CI -21.2%—23.0%, P=0.77). The greatest reduction was observed in 1-5 month-old children (24.9% lower, CI 10.6%—37.0%, P=0.001).Conclusions.Mass azithromycin distribution to post-neonatal, pre-school children may reduce childhood mortality in sub-Saharan Africa, particularly in high mortality areas such as Niger. Any implementation would need to consider selection for antibiotic resistance.
