School-based approaches to the correction of refractive error in children.

The World Health Organization estimates that 13 million children aged 5-15 years worldwide are visually impaired from uncorrected refractive error. School vision screening programs can identify and treat or refer children with refractive error. We concentrate on the findings of various screening studies and attempt to identify key factors in the success and sustainability of such programs in the developing world. We reviewed original and review articles describing children's vision and refractive error screening programs published in English and listed in PubMed, Medline OVID, Google Scholar, and Oxford University Electronic Resources databases. Data were abstracted on study objective, design, setting, participants, and outcomes, including accuracy of screening, quality of refractive services, barriers to uptake, impact on quality of life, and cost-effectiveness of programs. Inadequately corrected refractive error is an important global cause of visual impairment in childhood. School-based vision screening carried out by teachers and other ancillary personnel may be an effective means of detecting affected children and improving their visual function with spectacles. The need for services and potential impact of school-based programs varies widely between areas, depending on prevalence of refractive error and competing conditions and rates of school attendance. Barriers to acceptance of services include the cost and quality of available refractive care and mistaken beliefs that glasses will harm children's eyes. Further research is needed in areas such as the cost-effectiveness of different screening approaches and impact of education to promote acceptance of spectacle-wear. School vision programs should be integrated into comprehensive efforts to promote healthy children and their families.

An Irish eclipse prediction of AD 754: the earliest in the Latin West

This note announces the discovery of a tract on eclipse prediction in Paris, BnF, lat. 6400b, composed by an Irish scholar in ad 754. It is the earliest such text in the early middle ages and it is here placed in its scientific context.

C Dupré, The Age of Dignity (Hart 2015)

Bob Dylan famously searched high and low for it and left us wondering ‘what it’s gonna take’ to find it. These days, the elusive dignity – and her equally, if not more, elusive cousin human dignity – has captured the imagination of not just the poet and philosopher, but also, in light of its increasing prominence in an array of legal contexts, the legal scholar. Catherine Dupré’s The Age of Dignity comes at a high point in (human) dignity scholarship, with the publication of numerous texts in the English language emerging on the subject, and with interest in it looking unlikely to dissipate any time soon. In this review, I consider (human) dignity’s promise and pitfalls as it transpires in Dupré’s wide-ranging and ambitious monograph.
