Context. The chemical composition of the Sun is a fundamental yardstick in astronomy, relative to which essentially all cosmic objects are referenced. As such, having accurate knowledge solar elemental abundances crucial for an extremely broad range topics. Aims. We reassess 83 long-lived elements, using highly realistic modelling and state-of-the-art spectroscopic analysis techniques coupled w...

PURPOSE To identify the critical success factors (CSF) associated with coverage of low vision services. METHODS Data were collected from a survey distributed to Vision 2020 contacts, government, and non-government organizations (NGOs) in 195 countries. The Classification and Regression Tree Analysis (CART) was used to identify the critical success factors of low vision service coverage. Indep...

Blindness or low vision affects more than 3 million Americans 40 years and older, and this number is projected to reach 5.5 million by 2020. In addition to treating a patient's vision loss and comorbid medical issues, physicians must be aware of the physical limitations and social issues associated with vision loss to optimize health and independent living for the visually impaired patient. In ...

As part of the Vision 2020 Links Programme, a team from the Diabetes Eye Screening Department at Homerton University Hospital in London, UK visited the University Hospital of West Indies (UHWI) in Kingston, Jamaica in June 2015. The purpose of the visit was to share the Homerton team’s experiences with the UHWI’s ophthalmic department in support of their plans to start a pilot eye screening pro...

Onchocerciasis is one of the diseases targeted by Vision 2020. It is the world's second leading infectious cause of blindness, responsible for at least one million blind or severely visually disabled people. The Onchocerciasis Control Programme (OCP) in sub-Saharan Africa will be closed down in 2002, after 27 years of operation. This is the clearest indication that the prospects of eliminating ...

Blindness in children is considered a priority area for VISION 2020, as visually impaired children have a lifetime of blindness ahead of them.1 Various studies across the globe show that one-third to half of childhood blindness is either preventable or treatable1 and that cataract is the leading treatable cause of blindness in children.2 The 8th General Assembly of the International Agency for ...
