Citation network analysis on keratoconus

Journal of Optometry (2023)

César Villa Collar Cristina Álvarez-Peregrina Clara Martínez-Pérez Miguel Ángel Sánchez‐Tena

The high incidence of keratoconus has caused its management, etiology, and pathogenesis to be controversial topics in the ophthalmology field. This study aims to analyze the relationship between the different publications and authors through citation networks, as well as to identify the research areas and determine the most cited article. The search for publications was carried out through the Web of Science database, using the term "Keratoconus" between 1900 and December 2022. The Citation Network Explorer and CiteSpace software were used for the publication analysis. 9,655 publications were found, with 124,379 citations generated on the network. The year with the highest number of publications was 2021. The most cited publication was "Keratoconus" by Rabinowitz, published in 1998. Cluster function gave five groups of research areas about keratoconus: corneal signs and parameters, cross-linking efficiency and effects, clinical factors, keratoplasty, and treatment. The citation network offers an objective and comprehensive analysis of the papers on keratoconus.

Prevalence and estimation of the evolution of myopia in Spanish children

Research Square (Research Square) (2023)

Miguel Ángel Sánchez‐Tena Clara Martínez-Pérez César Villa Collar Mariano González-Pérez Ana González-Abad

Abstract Purpose: This study aims to analyze the myopia prevalence in Spanish children from five to seven years old over the last five years and to predict the rate of myopia in Spain by 2030. Methods: The sample consisted of children aged between 5 and 7, who underwent an optometric examination consisting of the measurement of visual acuity (VA) and determination of objective and subjective refraction. In addition, they completed a lifestyle questionnaire . The cut-off points to define the refractive error are established according to the spherical equivalent (SE) value as hyperopia, for SE over +0.50D, myopia, for SE under -0.50D, or emmetropia, when the SE is between -0.50D and +0.50D. Results: The myopia rate in Spanish children aged between five and seven was 19%. Myopia prevalence progressively increased as children grew up (p≤0.001). It is estimated that, in the year 2030, the rate of myopia will be 30.2% [CI: 25.3–35.0]. Of which 81.9% [CI: 78.3–85.3] will have low myopia, 10.0% [CI: 7.2–12.8] moderate myopia, and 7.3% [CI: 4.9–9.7] high myopia. Conclusion: Nineteen percent of Spanish children between five and seven are myopes. In 2030 is expected that 30.2% of Spanish children between 5 and 7 years of age will be myopes. These estimations will support eye care professionals in recommending children spend more time outdoors to prevent the onset of myopia and the use of methods to control myopia to avoid reaching these figures of high myopia.

A bibliometric and citation network analysis of crosslinking

European Journal of Ophthalmology (2024)

Miguel Ángel Sánchez‐Tena Clara Martínez-Pérez César Villa Collar Cristina Álvarez-Peregrina

Purpose: Research on crosslinking has focused mainly on trying to slow the progression of keratoconus. The objective of this bibliometric analysis is to determine the relationships between the different publications and authors. As well as to identify the different areas of research on crosslinking. Methods: Web of Science (WOS) was the database for the search of publications for the period 1972 to December 2023, using the terms: crosslinking, cross-linking, ocular, vision, visual, cornea, ectasia AND Keratoconus. The analysis of the publication was performed using the CitNetExplorer, VOSviewer and CiteSpace software. Results: 7161 publications and 59415 citation networks were found. The year with the most publications is 2021, a total of 571 (7.97%) publications and 135 citation networks. The most cited publication was “Riboflavin/ultraviolet-a-induced collagen crosslinking for the treatment of keratoconus” published by Wollensak et al. in 2003, with a citation index of 1780. Using the Clustering function, five groups were found that cover the main research areas in this field: keratoconus, corneal transplantation, cataracts, corneal inflammation and axial growth. Conclusion: The treatment of keratoconus continues to be the topic of interest in this area of research. However, in recent years there has been an increase in research on how crosslinking helps to slow down axial growth.

Filtros de corte selectivo para la Degeneración Macular Asociada a la Edad. Revisión bibliográfica

Gaceta de optometría y óptica oftálmica (2019)

D. Caballé Fontanet Cristina Álvarez Peregrina Miguel Ángel Sánchez‐Tena

Los pacientes con DMAE, sufren una disminucion del campo visual central, con la consiguiente perdida de la calidad de vida. En funcion del grado de severidad de la patologia y de las caracteristicas de cada persona, el paciente puede sufrir un deslumbramiento incomodo o un deslumbramiento incapacitante. La utilizacion de filtros de corte selectivo sirve para reducir la cantidad de longitud de onda carta y asi, disminuir el deslumbramiento, pero no se ha determinado el mejor color, tinte, material de la lente o incluso tipo de montura para estos pacientes. Se ha realizado un analisis de la bibliografia publicada hasta la fecha en torno al uso de los filtros de corte selectivo en la Degeneracion Macular Asociada a la Edad. El uso de estos filtros mejora en la calidad de vida del paciente, pero para poder normalizar el uso de los mismos, seria conveniente mejorar la clasificacion de la severidad de los pacientes, disenar nuevos test mas validos y ampliar los aspectos estudiados. La utilizacion de cuestionarios de la calidad de vida, pueden ayudar a cuantificar la percepcion subjetiva del paciente.

Vision in Futsal Players: Coordination and Reaction Time

International Journal of Environmental Research and Public Health (2021)

Henrique Nascimento Cristina Álvarez-Peregrina Clara Martínez-Pérez Miguel Ángel Sánchez‐Tena

Coordination and reaction time are relevant aspects of a sport's competitive performance within teams. The aim of this study was to explore if a group of futsal players, in a laboratory context, would present better results from actions where vision is prevalent compared to a control group without contact with futsal or any other sport.The digital system of the COI- SV software was used; six tests were selected, related to coordination ("Eye/hand coordination"; "Coordination and identification") and reaction time ("Anticipation Time"; "Peripheral response"; "reaction time"; "Visual memory").Of all the tests performed, only in the anticipation time test did the futsal players obtain better results than the control group. The average time of the failures was lower in relation to the control group. In the others, no differences were found between the two groups.The futsal players did not perform better than the control group in most of the tests carried out, except in the "anticipation time". Therefore, visual training maybe necessary to improve visual skills and sports performance.

Miguel Ángel Sánchez‐Tena Clara Martínez-Pérez César Villa Collar Cristina Álvarez-Peregrina

Background: The objective of this study is to determine the relationship between publications and authors. In turn, the different areas of research on the ocular complications of myopia are also identified, and the most cited publication by citation networks is determined. Methods: The search for publications is carried out in the Web of Science database using the term “myopia OR nearsightedness AND retin* OR degenerat* OR detachment OR patholog* OR glaucoma OR cataract OR machulopathy OR “choroidal neovascularization” for the period between 1978 and December 2022. Publication analysis was performed using the Citation Network Explorer, VOSviewer and CiteSpace software. Results: A total of 9357 publications and 78,400 citation networks were found across the network, with 2021 being the year with the highest number of publications, 712. The most cited publication was “Myopia”, published in The Lancet journal in 2012 by Morgan et al. with a citation index of 1006. By using the clustering function, seven groups covering the different research areas in this field were found: axial growth of the eye; myopic maculopathy; ocular complications in patients with myopia after a surgery; glaucoma; retinal detachment; cataracts and retinopathy of prematurity. Conclusions: The citation network offers a quantitative and qualitative analysis of the main papers on ocular complications of myopia. The research on this field is multidisciplinary; however, the main topic studied is the axial growth of the eye.
