[Bibliometric study and analysis of citation networks of visual screening in primary care]. / Estudio bibliométrico y análisis de redes de citación de los screening visuales en atención primaria.

AIM: Screenings make it possible to detect anomalies that can be treated and identify patients who require referral to a specialist. The objective is to identify the different areas of research and determine the most cited publications on screening in primary care. METHODS: An analysis of publications and visualization of citation networks has been carried out using the Citation Network Explorer software. The bibliographic search was carried out with the Web of Science (WOS) database using the search term: "screening AND (vision OR eye OR ocular OR visual)". RESULTS: We analyzed 16707 publications in all fields, 23919 citation networks have been found. The number of publications has increased, with 2021 being the year with the highest number. The majority are scientific articles and the predominant language is English. The most cited article is a global meta-analysis on the prevalence of glaucoma, showing the importance of screening for its early detection since it is essential to avoid blindness. Using the clustering function we found 8 groups with a significant number of publications where we have bibliography on certain eye diseases: glaucoma, diabetic retinopathy, pediatric amblyopia, keratoconus and dry eye. CONCLUSIONS: The main areas of study in relation to screening are the detection of diseases such as glaucoma, retinopathy of prematurity, keratoconus and dry eye. As well as the detection through visual analysis of childhood amblyopia and vision loss in elderly patients. It also gives importance to performing ocular motility tests in problems of acquired brain damage.

Estudio bibliométrico de cirugía refractiva y ojo seco en la literatura científica / Bibliometric study of refractive surgery and dry eye scientific literature

Antecedentes y objetivo La cirugía refractiva es actualmente un procedimiento seguro y eficaz, y es reconocida como factor de riesgo para el desarrollo del ojo seco. El objetivo del estudio es analizar la producción e identificar el estado de conocimiento sobre el ojo seco secundario a cirugía refractiva, sus inicios y su evolución, así como cuales son los autores e instituciones más notorios. Material y métodos Se realizó una búsqueda de referencias a través de la base de datos Scopus, utilizando «cirugía refractiva» como descriptor principal y «ojo seco» como secundario; unidos ambos por el operador booleano AND, y limitándose el campo a la disponibilidad de título, resumen y palabras clave. A las publicaciones seleccionadas se le aplicaron los indicadores y los mapas bibliométricos habituales. Resultados Se recopilaron 78 artículos del periodo 2001-2019. Según la ley de Price, el crecimiento de la producción de la literatura fue lineal. La tasa de crecimiento anual fue del 8,6% con un tiempo de duplicación de 8,4 años. El núcleo de Bradford ofreció 4 revistas, todas con factor de impacto>2. Estas fueron: Journal of Ophthalmology, Investigative Ophthalmology and Visual Science, Journal of Glaucoma y The British Journal of Ophthalmology. El país con mayor producción fue EE. UU. Conclusiones La producción científica sobre el ojo seco secundaria a cirugía refractiva sigue un crecimiento lineal, no cumpliéndose los postulados de Price. Existe una alta transitoriedad de autores. Esto puede indicar una baja productividad por autor, o bien la presencia alta de investigadores que hayan publicado publican ocasionalmente sobre este tema (AU)

Objective Currently, refractive surgery is a safe and effective procedure, and considered as a risk for development of dry eye. The aim of study is to analyze the scientific publications in the field of ocular dryness secondary to refractive surgery through a bibliometric approach. The temporal period goes since 2001 to 2019, years in which first references appeared and search limited selection is done, respectively. The set of publications ranges from the first publication appeared in 2001, to the last one selected in 2019. Methods A search of references was made through Scopus, using «refractive surgery» as main descriptor, and «dry eye» as secondary one; both descriptors were limited to those available in the chosen field for the title, abstract, and keywords. The most common indicators and bibliometric maps were applied for to the selected publications. Results A total of 78 original articles were collected from the timeframe 2001-2019. According to the Price's law, the growth of literature production was linear turned out in a linear growth of literature production. The annual growth rate was 8.6% with a literature doubling time of 8.4 years. The Bradford core, preferred journals chosen by authors were 4 with offered four preferred journals by the authors, all of them with an impact factor >2. These were Ophthalmology, Investigative Ophthalmology & Visual Science, Journal of Glaucoma and British Journal of Ophthalmology. Regarding geographical distribution, the United States had the highest production. Conclusions The scientific production of dry eye after refractive surgery follows a linear growth. In this instance, postulates of the Price's growth law of science are not fulfilled. In addition, there is a high rate of transience. That may indicate low productivity or presence of researchers from other related subjects disciplines, who have published occasionally in this topic (AU)

Citation network analysis of the various types of multifocal intraocular lenses.

BACKGROUND AND OBJECTIVE: The implantation of multifocal intraocular lens (IOL) has increased in recent years, allowing patients to achieve good quality vision at all distances, independence from use of glasses, and consequently, an increase in quality of life. The main purpose of this study was to analyse the links between publications and authors via citation networks, as well to as identify the different research areas and determine the most cited publications. MATERIAL AND METHODS: The publication search was performed through the Web of Science database, using the terms «Multifocal intraocular lens¼, «Bifocal intraocular lens¼, «Trifocal intraocular lens¼, «Diffractive intraocular lens¼, «Refractive intraocular lens¼, «Accommodative intraocular lens¼ and «Extended depth of focus intraocular lens¼, for a time interval from 1989 to August 2020. The software used to analyse the publications was the Citation Network Explorer. RESULTS: A total of 1293 publications were found, with 11,730 citations generated in the network, and 2019 had the highest number of publications of any year. The most cited publication was «European multicenter study of the AcrySof ReSTOR apodized diffractive intraocular lens¼ by Kohnen et al., published in 2006. Four groups about different research areas in this field were found using the Clustering functionality: visual quality, IOL designs, ocular aberrations, or defocus curves. CONCLUSIONS: The citation network offers an objective and comprehensive analysis of the main articles on the different designs and classes of multifocal IOL.

Adaptación cultural y validación al castellano del cuestionario National Eye Institute Visual Function Questionnaire 25 / Crosscultural adaptation and validation into Spanish of the questionnaire National Eye Institute Visual Function Questionnaire 25

INTRODUCCIÓN: Los avances en medicina han contribuido al aumento del promedio de vida, existiendo un mayor número de pacientes crónicos. Esto hace que la evaluación de la calidad de vida de los pacientes en varios aspectos, entre ellos el relacionado con su visión, haya adquirido una especial importancia. OBJETIVO: Validación de la traducción y adaptación cultural al castellano de uno de los cuestionarios de calidad de vida relacionada con la visión más ampliamente empleados. Se ha buscado que el cuestionario en castellano sea equivalente semántica y conceptualmente, así como de contenido técnico y de criterio que el ya validado en inglés. MÉTODO: Estudio observacional analítico de una cohorte de pacientes en los que se ha analizado la calidad de vida relacionada con la visión. El estudio se ha desarrollado en 2 fases, una primera de traducción y adaptación cultural al castellano del cuestionario NEI VFQ-25 y, la segunda, de estudio psicométrico de la fiabilidad y validez de la escala en la versión en castellano. RESULTADOS: El análisis de fiabilidad y validez refleja que la traducción y adaptación cultural cumple con los requisitos esperados y ha sido bien aceptada por los usuarios. CONCLUSIÓN: Se puede disponer de un cuestionario validado en castellano para evaluar la calidad de vida en pacientes con enfermedades crónicas como la degeneración macular asociada a la edad

INTRODUCTION: Advances in medicine have contributed to a higher average life expectancy, as well as an increasing number of chronic diseases patients. This longevity means that the assessment of the quality of life, particularly that related to vision, has become very relevant. OBJECTIVE: The validation of the translation and cross-cultural adaptation into Spanish of one of the most widely used vision-related quality of life questionnaires. It has sought to ensure that the Spanish version of the questionnaire was equivalent in semantic, conceptual, and technical content and criteria level, compared to its already validated English version. METHOD: An analytical observational study was conducted using a cohort of patients, in whom their quality of life related to vision was analysed. The study was developed in two steps; the first was the translation and cross-cultural adaptation to Spanish of the NEI VFQ-25 questionnaire. The second one was the psychometric study of the reliability and validity of the scale of the Spanish version. RESULTS: The analysis of the terms of reliability and validity showed that the translation and cross-cultural adaptation met the expected requirements and was well accepted by users. CONCLUSION: There is now a possibility of having a Spanish validated questionnaire available to assess the quality of life related to vision in patients with chronic diseases, such as age-related macular degeneration
