Background: There is a growing awareness that addressing chronic as well as acute health conditions may contribute importantly to the well-being of displaced populations, but eye care service has generally not been prioritized in crisis situations. We describe a replicable model of eye care provision as delivered by Orbis International and local partners to the Rohingya and host population in Cox's Bazar, Bangladesh, and characterize the burden of vision impairment and demand for sight-restoring services in this setting.Methods and Findings: Orbis International and local secondary facility Cox's Bazar Baitush Sharaf Hospital (CBBSH) provide eye care support to the Rohingya population and the host community of all ages in Cox's Bazar, Bangladesh, with fixed vision screening locations established in Camps 4 and 11 of the Kutupalong refugee settlement. Structured outreach targets these camps and four surrounding local subdistricts, with referrals made as needed for refraction (glasses measurement) and cataract surgery to CBBSH. Between February 2018 and March 2019, 48,105 displaced Rohingya (70.3%, among whom 71.6% were children and 46.5% women) and 20,357 local residents (29.7%, 88.5% children, 54.4% women) underwent vision screening. Displaced Rohingya sought services from a total of 12 surrounding camps, within which coverage was 17.3%, including 43.3% (27,027/62,424) of children aged 5-11 years and 60.0% (5,315/8,857) of adults ≥ 60 years old. The prevalence of blindness (presenting acuity < 3/60) among Rohingya patients exceeded that among local residents by 3- to 6-fold in each 10-year age group between 18 and 59 years (P < 0.001 comparing vision between the two groups in this age range), and the prevalence of cataract requiring surgery was also higher in Rohingya patients (18-29 years: 4.67% versus 1.80%, P = 0.0019; 30-39: 7.61% versus 2.39%, P < 0.001; and 40-49 years: 7.91% versus 3.77%, P = 0.0014). A limitation of the study is lack of data on population prevalence of eye disease.Conclusions: The burden of untreated eye disease is very high among the Rohingya, particularly those in their peak working years who could contribute most to the resiliency of their community. Demand for eye care service is also great among children and adults in this population with many competing healthcare priorities. Research is needed, building on strong evidence of benefit in settled populations, to explore the specific impact of vision care on the well-being of displaced populations. [ABSTRACT FROM AUTHOR]

To test a model of integrated pediatric eye care delivery and examine the prevalence and factors associated with childhood ocular morbidity in a peri-urban setting in Bangladesh. Cross-sectional, population-based study. The study was conducted in three phases among children aged ≤15 years. Trained community health workers (CHWs) conducted awareness intervention and identified children with ocular problems. These children were then referred to the base hospital for examination and treatment by ophthalmologists. A pediatric ophthalmologist further examined the children with complicated eye diseases and ensured treatment at a tertiary public eye hospital. Awareness, referral patterns, and health-seeking behavior were also examined. All data were analyzed statistically using Statistical Package for Social Sciences. CHWs screened 33,549 eligible children and identified 1887 cases with ocular morbidity. The prevalence of ocular morbidity and childhood blindness were 5.63% (95% confidence interval [CI] = 5.27–6.16) and 0.060% (95% CI = 0.03–0.11), respectively. The most commonly observed ocular morbidities were refractive error (3.24%; 95% CI = 3.11–3.45), allergic eye conditions (1.2%; 95% = CI 0.74–1.27), and nasolacrimal duct obstruction (0.52%; 95% CI = 0.25–0.74). Blindness was more frequently seen in children aged <5 years than in those aged 5–15 years (χ2 = 7.25; P = 0.007). The causes of blindness were corneal opacity, congenital eye anomaly, cataract, retinopathy of prematurity, and retinoblastoma. The prevalence of ocular morbidity was higher among older children, boys, children with low parental education and income, and children from households dwelling in slums. This study demonstrated that in a setting where screening and treatment for vision problems remain low, ocular morbidity among children could be easily identified through well-designed community-based screening programs involving appropriately trained CHWs. Community mobilization, awareness, and early detection of childhood eye diseases, with effective referral mechanisms for accessing appropriate care, are crucially important to improve service delivery. • Trained community health workers conducted awareness interventions, identified and referred children with ocular problems. • Refractive error was the most common ocular morbidity. • Ocular morbidity was associated with older children and slum dwellers. • Gender inequalities existed in care seeking; fewer girls sought care from the referral hospital. • Community mobilization, early detection and effective referral are important for improving eye care service delivery.
