    Introduction: Health Sciences are a branch of science of great social and economic interest. A bibliometric analysis of scientific journals related to optometry in Colombia can contribute to improving the level of research in this field. Aim: to recognize the bibliometric behavior of scientific journals related to Optometry, published in Colombia, during the period 2014 - 2019. Material and methods: a descriptive-retrospective bibliometric analysis was carried out with cross section of 241 publications made in the five scientific journals related to Optometry existing in the country. Results: it was found that the prevalent subject area in the articles reviewed was Diagnosis and Treatment. Multi-authorship from 2 to 5 authors is preponderant. Scientific journals have high isolates. Citations in a language other than Spanish exceeded 50% in the 5 magazines. The most used specific design was the descriptive cross section. Type of document most used was research. The descriptor with the highest appearance was Retina.

    Prevalence of Ametropia, Amblyopia and visual impairment in schoolchildren in Ireland

    Background: Uncorrected refractive error is an avoidable cause of visual impairment (Naidoo et al., 2016). Currently, there is a lack of adequate data on eye and vision disorders in schoolchildren in Ireland. Accurate prevalence estimates of refractive error and vision disorders are necessary to determine their impact on public health and to assess the need for interventions (McCarty and Taylor, 2000). Purpose: This study reports the prevalence of ametropia, presenting visual impairment, amblyopia and provides population norms for ocular biometric measures in schoolchildren in Ireland. Links between refractive error and demographic and lifestyle factors were investigated. The impact of poor presenting vision, on participants’ educational performance, was also examined. Methods: The Ireland Eye Study examined 1,626 children (881 boys, 745 girls) in two age groups, 6-7 years (728) and 12-13 years (898), in the Republic of Ireland (henceforth Ireland) between June 2016 and January 2018. Participating schools were selected by stratified random sampling, representing a mix of school type (primary/post-primary), location (urban/rural) and socioeconomic status (disadvantaged/advantaged). Parents completed a questionnaire which provided information on participants’ lifestyle and participants’ school performance. Examination included monocular logMAR visual acuity (both presenting with spectacles if worn and through a pinhole), cycloplegic auto-refraction (Cyclopentolate Hydrochloride 1%), non-contact ocular biometry (IOLMaster), and ocular alignment (cover test). Results: The prevalence of myopia (≤-0.50 D), hyperopia (≥+2.00 D), and astigmatism (≥1.00 DC) in 6-7-year-olds was 3.3%, 25.0%, 19.2%, respectively, and amongst 12-13-year-old children, 19.9%, 8.9% and 15.9%, respectively. Astigmatism axes were mostly with-the-rule (80.3%). The prevalence of presenting visual impairment in the “better ii eye” (≥0.3logMAR, with spectacles, if worn) was 3.7% amongst younger and 3.4% amongst older participants and associated with Traveller and non-White ethnicity. Amblyopia prevalence (pin-hole visual acuity ≥0.3logMAR plus an amblyogenic factor), was high (6-7 years 5.5%, 12-13 years 3.7%) compared to other studies. Amblyopia prevalence was primarily due to uncorrected refractive error. Compliance with spectacle wear, socioeconomic disadvantage and sedentary lifestyle were also contributing factors. Factors associated with myopia included age group, ethnicity, screen-time, time spent outdoors during daylight, obesity and sedentary lifestyle. Astigmatism was significantly associated with visual impairment and amblyopia. Time spent outdoors during daylight in summer was associated with a significantly less myopic SER and shorter axial length in White participants. Poor educational performance was associated with presenting visual impairment and amblyopia

    Big Data: Potential as an Ocular Epidemiology and Public Health Tool

    Get PDF
    Refractive error is a significant cause of vision impairment both through the limited access to correction in some areas and the associated ocular diseases for which refractive errors are risk factors. Having timely, regular access to population level estimates of refractive error and vision impairment is necessary to adequately plan public health resources and resource appropriate interventions. A lack of access to current and regularly updated refractive error and vision impairment prevalence data has been identified as a significant limitation in predicting future population trends with many countries lacking any prevalence data or available data being outdated. This project addresses this gap by utilising the untapped potential of Big Data in the form of spectacle lens sales data and optometric electronic medical record data and assesses the potential of these data sources as a public health tool. Chapter 5 contains a review of the application of Big Data and Artificial Intelligence to the field of eyecare and describes the revolutionary potential these new technologies may hold. Chapter 6 describes the data used in this project and the steps taken to acquire and clean the data. Chapter 7 and 8 compare the prevalence of refractive error found using spectacle lens sales data and optometric electronic medical record data to a large population survey of refractive error and demonstrate that with careful analysis an accurate estimation of population distribution of refractive error can be obtained from both types of data. Chapter 8 also estimates the likely level of vision impairment by age 75 given the distribution of myopia in the spectacle lens sales data. Chapter 9 analyses visual acuity data within the optometric electronic medical records which allowed the optimum recall interval and visual acuity threshold for driving licence renewal to be determined. Chapter 10 provides a summary and conclusion on the work, and contains recommendations for future research

    Visual Impairment and Blindness

    Blindness and vision impairment affect at least 2.2 billion people worldwide with most individuals having a preventable vision impairment. The majority of people with vision impairment are older than 50 years, however, vision loss can affect people of all ages. Reduced eyesight can have major and long-lasting effects on all aspects of life, including daily personal activities, interacting with the community, school and work opportunities, and the ability to access public services. This book provides an overview of the effects of blindness and visual impairment in the context of the most common causes of blindness in older adults as well as children, including retinal disorders, cataracts, glaucoma, and macular or corneal degeneration
