Bibliometric study of scientific research on optometric visual therapy

2020 
espanolObjetivo Analizar la investigacion cientifica en el campo de la terapia visual, a traves de un estudio bibliometrico. Metodos La base de datos utilizada en este estudio bibliometrico fue SCOPUS, la mayor base de datos de resumenes y citas de la literatura revisada por pares, que cubre publicaciones cientificas, libros y actas de conferencias. Utilizando tecnicas de descargas remotas, se seleccionaron los articulos publicados entre 1946 y 2017 introduciendo los descriptores principales: "optometric vis* training", "optometric vis* therapy", "vis* therapy", "vis* training" limitados al titulo, las palabras clave y/o el resumen. Aplicamos los siguientes indicadores bibliometricos: indice de Price, tiempo de duplicado y tasa de crecimiento anual, indice de transitoriedad de Price, Ley de Lotka, factor h, y zonas de Bradford. Resultados Los autores recuperaron 294 articulos originales del intervalo temporal 1946-2017 (articulos, revisiones, cartas al director, etc.), descartando 15 de ellos por no cumplir los requisitos del estudio. La tasa de crecimiento anual fue del 39,62%, conteniendo el marco temporal 1987-1983 el mayor numero de documentos. Estados Unidos fue el pais mas productivo, con mas del 60% de los registros. Las instituciones mas productivas son: State University of New York System, SUNY State College of Optometry, y Southern California College of Optometry. La clasificacion de los autores basada en la productividad esta fuertemente concentrada en pequenos productores, con un indice de transitoriedad de 80,53. El numero total de autores fue de 488, lo cual representa un indice de co-autoria de 1,75. Conclusion Los estudios bibliometricos han resultado ser herramientas esenciales para evaluar las publicaciones cientificas. EnglishPurpose To analyze scientific research in the field of visual therapy through a bibliometric study. Methods The database used in this bibliometric study was SCOPUS, the largest abstract and citation database of peer-reviewed literature, covering scientific journals, books, and conference proceedings. Using remote downloading techniques, articles published between 1946 and 2017 were selected by entering the main descriptors: "optometric vis* training", "optometric vis* therapy", "vis* therapy", "vis* training" limited to the title, key words and/or abstract. We applied the following bibliometric indicators: Price’s index, doubling time and annual growth rate, Price’s transience index, Lotka’s Law, h factor, and Bradford’s zones. Results The authors retrieved 294 original articles from the temporal interval 1946–2017 (articles, reviews, letters to the director, etc.), discarding 15 of them for not meeting the study requirements. Annual growth rate was 39.62%, the timeframe 1987-1983 containing the most number of documents. United States was the country with the highest production, with more than 60% of the records. The most productive institutions are State University of New York System, SUNY State College of Optometry, and Southern California College of Optometry. Classification of authors based on productivity is strongly concentrated in small producers, with a transient index of 80.53. The total number of authors was 488, representing a co-authorship index of 1.75. Conclusion Bibliometric studies have become essential tools for assessing scientific publications.
