Detection of Neurological and Ophthalmological Pathologies with Optical Coherence Tomography Using Retinal Thickness Measurements: A Bibliometric Study

Abstract

We carry out a bibliometric analysis on neurological and ophthalmological pathologies based on retinal nerve fiber layer (RNFL) thickness measured with optical coherence tomography (OCT). Documents were selected from Scopus database. We have applied the most commonly used bibliometric indicators, both for production and dispersion, as Price’s law of scientific literature growth, Lotka’s law, the transient index, and the Bradford model. Finally, the participation index of the different countries and affiliations was calculated. Two-hundred-and-forty-one documents from the period 2000–2019 were retrieved. Scientific production was better adjusted to linear growth (r = 0.88) than exponential (r = 0.87). The duplication time of the documents obtained was 5.6 years. The transience index was 89.62%, which indicates that most of the scientific production is due to very few authors. The signature rate per document was 5.2. Nine journals made up the Bradford core. USA and University of California present the highest production. The most frequently discussed topics on RNFL thinning are glaucoma and neurodegenerative diseases (NDD). The growth of the scientific literature on RNFL thickness was linear, with a very high rate of transience, which indicates low productivity and the presence of numerous authors who sporadically publish on this topic. No evidence of a saturation point was observed. In the last 10 years, there has been an increase in documents relating the decline of RNFL to NDD.

Comparison of Machine Learning Methods Using Spectralis OCT for Diagnosis and Disability Progression Prognosis in Multiple Sclerosis

“…This fact highlights the importance of studying neuroretina as a possible MS biomarker. 13 , 45 Optical coherence tomography (OCT) is a non-invasive, objective and reproducible method to monitor retinal damage. OCT devices provide measurements of each retinal layer and, therefore, show great potential for quantifying axonal damage by measuring peripapillary retinal nerve fiber layer (pRNFL) and macular RNFL (mRNFL) thicknesses.…”

International Scientific Research on Venture Capital: a Bibliometric and Mapping Analysis from the Period 1978–2020

“…After downloading the metadata and exact bibliographic details of all venture capital publications, the results were analyzed according to the following criteria: chronological distribution, country of origin, affiliation, sources and authors of the documents, keywords and descriptors used. The methodology applied in this study was comparable to recent bibliometric studies of our group [24][25][26][27][28].…”

“…Our group has used a bibliometric approach to study the evolution of scientific literature in different areas of the science [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], but, to the best of our knowledge, there is not such work applied to the field of knowledge of venture capital. There has indeed been a recent Delphi process on the usefulness and expected changes of venture capital within the research area, highlighting the role that venture capital research might pose on the ongoing structural changes in the industry and decision-making processes.…”

The crossroads of melatonin: Bibliometric analysis and mapping of global scientific research

“…After downloading the metadata and exact bibliographic details of all melatonin publications, the results were analyzed according to the criteria of chronological distribution, country of origin, affiliation, sources and authors of the documents, keywords and descriptors used. The methodology applied in this study was comparable to recent bibliometric studies of our group (32,34,37,38).…”

“…Bibliometrics includes the collection, processing and management of quantitative bibliographic data from scientific publications (20), and their statistical indicators allow measurement of the growth, size and distribution of scientific literature on the topic in question during a given time period (21). Our research group has studied, using a bibliometric approach, the evolution of scientific literature in different areas of neurosciences by several research groups, involving diverse psychiatric disorders and characteristics related, as well as specific therapeutic tools in the field of psychopharmacology (22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34), including the evolution of publications on the pineal gland during the period 1966-1994 (35), and 1900-2014 (36). In this sense, to detail its distribution, and interpret the changes that have affected its development, we focused our attention on the bibliometric analysis of the scientific production on melatonin since the discovery of this hormone in 1958 until 2019, to identify the groupings and trends of the research on this topic.…”
