Evidence-based practice is a dominant paradigm in healthcare that emphasizes the importance of ensuring the translation of the best available, relevant research evidence into practice. An Evidence Quality Subcommittee was established to provide specialized methodological support and expertise to promote rigorous and evidence-based approaches for the Tear Film and Ocular Surface Society (TFOS) Lifestyle Epidemic reports. The present report describes the purpose, scope, and activity of the Evidence Quality Subcommittee in the undertaking of high-quality narrative-style literature reviews, and leading prospectively registered, reliable systematic reviews of high priority research questions, using standardized methods for each topic area report. Identification of …

Eye strain when performing tasks reliant on a digital environment can cause discomfort, affecting productivity and quality of life. Digital eye strain (the preferred terminology) was defined as “the development or exacerbation of recurrent ocular symptoms and/or signs related specifically to digital device screen viewing”. Digital eye strain prevalence of up to 97% has been reported, due to no previously agreed definition/diagnostic criteria and limitations of current questionnaires which fail to differentiate such symptoms from those arising from nondigital tasks. Objective signs such as blink rate or critical flicker frequency changes are not ‘diagnostic’ of digital eye strain nor validated …

Systematic Review Of Clinical Practice Guidelines For Uveitis, Nima Ghadiri, Ian R. Reekie, Iris Gordon, Sare Safi, Gareth Lingham, Jennifer R. Evans, Stuart Keel

To facilitate the integration of eye care into universal health coverage, the WHO is developing a Package of Eye Care Interventions (PECI). Development of the PECI involves the identification of evidence-based interventions from relevant clinical practice guidelines (CPGs) for uveitis.

A systematic review of CPGs published on uveitis between 2010 and March 2020 was conducted. CPGs passing title and abstract and full-text screening were evaluated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool and data on recommended interventions extracted using a standard data extraction sheet.

Review Of Recent Advances In Photosensitive Polymer Materials And Requirements For Transmission Diffractive Optical Elements For Led Light Sources, Michael Murray, Izabela Naydenova, Suzanne Martin

Articles

Scattered light from outdoor LED sources is a major contributor to blue-spectrum light pollution which negatively impacts ecology and public health. Volume holographic diffractive optical elements (DOEs), made with low-cost photosensitive polymers, are proposed as a technological solution that can minimise this scattering. This review examines requirements needed for efficient operation of transmission-format DOEs with LEDs and implications for material choices. For such DOEs to have a single diffraction order and high efficiency there is a corresponding range of acceptable Δn. A survey of materials also found that many current materials satisfy the Δn requirements for single-element DOEs. It is …
