Do Ophthalmology Journals Have AI Policies for Manuscript Writing?

PurposeTo assess the prevalence of Artificial Intelligence (AI) usage policies in manuscript writing in PubMed-indexed ophthalmology journals and examine the relationship between adoption of these policies and journal characteristics. DesignCross-sectional study SubjectsPubMed-indexed ophthalmology journals Main Outcome MeasuresPrevalence of policies in journal guidelines regarding the use of AI in manuscript writing. MethodsWe reviewed the guidelines of 84 ophthalmology journals indexed in PubMed to determine the presence of AI-use policies for manuscript generation. We further compared journal metrics, such as CiteScore, Journal Impact Factor (JIF), Journal Citation Indicator (JCI), Source Normalized Impact per Paper (SNIP), and SCImago Journal Rank (SJR), between journals with and without AI policies. Additionally, we analyzed the association between AI policy adoption and journal characteristics, such as MEDLINE indexing and society affiliation. ResultsAmong the 84 journals, 53 (63.1%) had AI policies for manuscript generation, with no significant changes observed during the study period. Journals indexed in MEDLINE were significantly more likely to have AI policies (68.8%) than non-MEDLINE-indexed journals, where no AI policies were found (0%) (p = 0.0008). There was no significant difference in AI policy adoption between society-affiliated (62.7%) and unaffiliated journals (64.7%) (p = 0.8443). Journals with AI policies had significantly higher metrics, including CiteScore, SNIP, SJR, JIF, and JCI (p < 0.05). ConclusionsWhile many ophthalmology journals have adopted AI policies, the lack of guidelines in over one-third of journals highlights a critical need for consistent and comprehensive AI policies, particularly as the AI landscape rapidly advances.

To conduct a bibliometric analysis of research on artificial intelligence (AI) in the field of glaucoma to gain a comprehensive understanding of the current state of research and identify potential new directions for future studies. Relevant articles on the application of AI in the field of glaucoma from the Web of Science Core Collection were retrieved, covering the period from January 1, 2013, to December 31, 2022. In order to assess the contributions and co-occurrence relationships among different countries/regions, institutions, authors, and journals, CiteSpace and VOSviewer software were employed and the research hotspots and future trends within the field were identified. A total of 750 English articles published between 2013 and 2022 were collected, and the number of publications exhibited an overall increasing trend. The majority of the articles were from China, followed by the United States and India. National University of Singapore, Chinese Academy of Sciences, and Sun Yat-sen University made significant contributions to the published works. Weinreb RN and Fu HZ ranked first among authors and cited authors. American Journal of Ophthalmology is the most impactful academic journal in the field of AI application in glaucoma. The disciplinary scope of this field includes ophthalmology, computer science, mathematics, molecular biology, genetics, and other related disciplines. The clustering and identification of keyword nodes in the co-occurrence network reveal the evolving landscape of AI application in the field of glaucoma. Initially, the hot topics in this field were primarily "segmentation", "classification" and "diagnosis". However, in recent years, the focus has shifted to "deep learning", "convolutional neural network" and "artificial intelligence". With the rapid development of AI technology, scholars have shown increasing interest in its application in the field of glaucoma. Moreover, the application of AI in assisting treatment and predicting prognosis in glaucoma may become a future research hotspot. However, the reliability and interpretability of AI data remain pressing issues that require resolution.

The multifaceted factors affecting the publication times of pediatric ophthalmology and strabismus articles: what has changed in two decades

AbstractExpeditious publication is an important factor when considering publishing ophthalmic research. We investigated the factors associated with shorter publication times in pediatric ophthalmology and strabismus (POS). We analyzed 2487 POS articles from 8 ophthalmology journals publishing POS articles. Time from submission to acceptance, from acceptance to publication, and from submission to publication were calculated for each article. We compared trends over time of factors affecting the publication times from 2002 to 2007 and those from 2014 to 2018. Median peer review durations were 156 days from submission to acceptance; 79 days from acceptance to publication, and 244 days from submission to publication. The American Journal of Ophthalmology, JAMA Ophthalmology, and Strabismus had the shortest submission to publication time. Authors from Africa, East Europe, Central and South America received the fastest processing time in all time categories, although most authors were based in North America and UK. All-time intervals decreased annually, significantly more during the first decade. In the study's second period, more co-authors and affiliated departments correlated with shorter review times. Manuscripts in higher Impact Factor (IF) journals had faster publication times in the first decade. Female senior authors faced longer submission-to-acceptance times in the first decade. This gender gap disappeared in the second period. A general improvement occurred with most journals, specifically those journals with a higher number of co-authors and affiliated departments, indicating an efficient collaborative authorship. Low-income regions benefited from comparatively shorter time intervals. The gender gap in senior authorship diminished over time.

PurposeCharacterize geographical trends in ophthalmology research between 2002-2022 and explore associations between study locations, designs, and funding sources DesignTrend study MethodsAnalysis of 4199 publications from American Journal of Ophthalmology, British Journal of Ophthalmology, Investigative Ophthalmology and Visual Science, JAMA Ophthalmology, and Ophthalmology. All original full-length publications from 2002, 2012, and 2022 were included. Exclusion criteria were meta-analyses, literature reviews, and case reports. Main outcome measures were publication years, locations, study designs, and funding sources. ResultsPublications from North America (45.8%), Europe (30.7%), and Asia (28.9%) were the most common, whereas Africa (0.8%) and South America (1.4%) were least represented. North American research decreased by 10.6% (p < 0.001), whereas Asian research increased by 25.4% (p < 0.001). The USA contributed 42.3% of research but experienced a 11.3% decline from 2002-2022 (p < 0.001). USA publications received 5.8% more industry funding from 2002-2022 (p = 0.006). China's research grew by 17.0% and had the highest proportion of government (83.1%) or intramural (24.2%) funding (p < 0.001), with government-funded studies increasing by 46.7% (p < 0.001). Japan was less associated with all funding types (p ≤ 0.001). Singapore, Iceland, and Switzerland were top performers when adjusted for population size. ConclusionsWithin the examined journals, the USA remains the primary research contributor, with China witnessing rapid growth and Japan facing stagnation. Despite the USA's declining research proportion, North America and Europe continue to maintain a disproportionately high presence in prestigious academic journals. Publications from Africa and South America are limited.

Gender inclusivity of ophthalmology journal submission guidelines and associated research metrics.

This cross-sectional study evaluated the prevalence of inclusive author submission guidelines across ophthalmology journals. Journals were identified from the 2021 Journal Citations Report (Clarivate Analytics). Independent reviewers rated each author submission guideline as "inclusive" for satisfying at-least one of six criteria: i) included examples of gender inclusive language; ii) recommended the use of gender-inclusive language; iii) distinguished between sex and gender; iv) provided educational resources on gender-inclusive language; v) provided a policy permitting name changes (e.g., in case of gender and name transition); and/or vi) provided a statement of commitment to inclusivity. The primary objective was to investigate the proportion of journals with "gender-inclusive" author submission guidelines and the elements of the gender-inclusive content within these guidelines. A secondary objective was to review the association between "gender-inclusivity" in author submission guidelines with publisher, origin country, and journal/source/influence metrics (Clarivate Analytics). Across 94 journals, 29.8% journals were rated as inclusive. Inclusive journals had significantly higher relative impact factor, citations, and article influence scores compared to non-inclusive journals. Of the 29.8% of inclusive journals, the three most common domains were inclusion of an inclusivity statement (71.4% of inclusive journals), distinguishing between sex and gender (67.9%), and provision of additional educational resources on gender reporting for authors (60.7%). A minority of ophthalmology journals have gender-inclusive author submission guidelines. Ophthalmology journals should update their submission guidelines to advance gender equity of both authors and study participants and promote the inclusion of gender-diverse communities.

The involvement of clinicians in the most highly cited publications on artificial intelligence in ophthalmology indexed journals

PurposeSignificant advances in artificial intelligence (AI) have led to promising applications in ophthalmology. This study highlights the involvement of clinicians in the most cited ophthalmology publications on AI in ophthalmology journals indexed by Web of Science. MethodsArticles examining AI in ophthalmology journals were processed from Web of Science. After selecting relevant articles, we performed bibliometric analyses at the article and author levels as of March 2024. The primary outcome measure was the number of citations per article. Secondary outcomes included article measures (publication year, subspecialties, article type, databases, imaging) and author attributes (gender, academic metrics, location). ResultsThe top 100 publications were cited between 58 and 734 times, with a median of 91 citations. Publication reprint addresses were mainly based in America (44) and in Europe (22). Common subspecialties were retina (60), glaucoma (44) and cornea (18). Most imaging modalities were fundus photography (47), optical coherence tomography (47) and visual fields (19). 76 studies were aimed at the development and evaluation of a diagnostic technology. Some private databases (44 %) and public databases (40 %) were specified. Among the 399 men and 163 women authors, 297 were physicians (52.9 %). Women and men had significantly different h-indexes (women: 23 [interquartile range (IQR): 13–46] vs. men: 38.5 [17–65]; P = 0.02) and number of published documents (women: 104 [32–277] vs. men: 188.5 [63.5–394]; P = 0.03). ConclusionThe most influential articles in AI and ophthalmology by number of citations predominantly used AI for image recognition and improving diagnostic technology in retina followed by glaucoma. Physicians had a predominant role in these, highlighting the continued importance of clinician involvement in this research.

Female representation on editorial boards of leading ophthalmology journals

PurposeTo assess the gender distribution of editorial board members of the leading ophthalmology journals according to SCImago Journal and Country Rank (SJR). MethodsTo evaluate the editorial boards of the ophthalmological journals in category Q1 of the SJR in a cross-sectional study. The primary outcome measured was the proportion of women as editor-in-chief and editorial board members. For the top 10 journals, the internal composition of the editorial board was analyzed and classified into four categories. The study was performed in Oftalmosalud Instituto de Ojos, Lima, Peru, from July to October 2022. In addition, the authors analyzed the women’s participation in previous years as editorial board members. ResultsThirty-two ophthalmology journals were classified within the Q1 category. Female representation as editor-in-chief of Q1 ophthalmology journals was 14.63% (6/41) and as part of the editorial board was 32.9% (122/371). In the top 10 ophthalmology journals, none of the editors-in-chief (Category I) was a woman (p < .001); 11% (11/100) in category II (p < .001), 38.42% (88/229) in Category III (p < .001), and 32.25% (10/31) in category IV (p = 0.07) were women. There was no significant correlation between the percentage of female representation and the SJR (r = 0.32, p = 0.07). ConclusionWomen are underrepresented among editorial board members of the leading ophthalmological journals and this disparity is greater in senior positions. However, there has been an increase in participation through the years.

Analysis of 50 Most Cited Articles About Refractive Surgery From an Altmetric Perspective.

The purpose of this study is to evaluate an Altmetric analysis of the 50 most cited refractive surgery articles in Ophthalmology journals and to compare them with traditional metrics. The term "refractive surgery" was searched, using a time filter between 2010-2020 in the Web of Science core collection database. The 50 most cited articles between 2010 and 2020 were recorded. Descriptive statistics were performed. The Spearman correlation test was used to evaluate the correlation between traditional metrics and Altmetrics. The Altmetric scores of the top 50 articles ranged from 0 to 25, and the median Altmetric score was 4. The citation numbers of the 50 articles ranged from 83 to 523, and the median citation number was 119.5. The most cited article topic was "Toric Intraocular Lens"; the topics with the highest Altmetric scores were "Toric Intraocular Lens" and "Trifocal Intraocular Lens". There was no significant correlation between Altmetric scores and number of citations. There was a weak correlation between Altmetric scores and the average citation per year. The Altmetric score is insufficient, compared with traditional metrics, to show the scientific value of articles on refractive surgery. Altmetrics can be used to supplement traditional metrics.

Lack of racial and ethnic diversity in pediatric ophthalmology clinical trials from 2000 to 2022

PurposeTo examine the prevalence of and factors associated with racial and ethnic reporting and trends in such reporting and to assess whether categories of race and ethnicity have been under- or over-represented in pediatric ophthalmology randomized control trials (RCTs) in the United States. MethodsWe systematically searched the literature on pediatric ophthalmology RCTs in high-impact factor ophthalmology journals published between 2000 and 2022. Logistic regression was used to assess parameters linked to race/ethnicity reporting; linear regression, to gauge the relationship between publication year and race/ethnicity reporting. The racial and ethnic composition of RCTs was contrasted with 2010 US census data by calculating percentage difference. ResultsOf 170 eligible articles, 89 (52.4%) included race/ethnicity data. Multivariable analysis showed that academic (OR = 12.19; 95% CI, 3.34-44.44) and government (OR = 3.91; 95% CI, 1.20-12.72) funding was linked to data reporting. During the study period, publication year and race/ethnicity reporting had a nonstatistically significant 1.0% annual increase (r = 0.29, P = 0.18). White participants were over-represented, with a percentage difference of 16.7% (95% CI, 11.8%-21.7%), whereas Hispanic individuals were under-represented, with a percentage difference of −7.6% (95% CI, −11.2% to −4.1%) compared to the 2010 US census data. ConclusionsOur results indicate a gradual rise in reported race and/or ethnicity in published pediatric ophthalmology RCTs, though not statistically significant, both in the United States and globally. Notably, under-representation of Hispanic, over-representation of White, and proportional representation of Black and Asian individuals were observed in US-based studies.

Bibliometric analysis of publication trends on ocular hygiene and infections in the past two decades.

Ocular hygiene encompasses a spectrum of measures to initiate and maintain adequate ocular cleanliness to prevent eye infections and their further transmission. These infections affect all age groups and can lead to severe complications such as blindness. Nearly 1 billion cases could have been prevented out of over 2.2 billion people that are visually impaired worldwide. This bibliometric analysis focuses on the papers published on ocular hygiene and infections. We searched in the Scopus database from 2004 to 2024. After manual screening, a list of the 100 most-cited original articles was obtained, which was analysed for various factors, including temporal trends, subject areas, authorship patterns, country of origin, funding bodies, etc. There has been a gradual decline over the past two decades in the number of publications. The United States was affiliated with the highest number of publications (n=61), followed by The United Kingdom (n=12) and Gambia (n=8). Several authors had 4 or more publications, with the highest number of publications by Rouse, B. T. (n=14). The American Journal of Ophthalmology takes the lead with 15 publications, while the National Eye Institute (n=23) was the leading funding body. Examination of institutional contributions shows that The University of Tennessee, Knoxville and UT College of Veterinary Medicine stand out with twelve publications each. Nearly half the publications belong to the field of medicine. However, significant publications also come from the fields Neuroscience, Microbiology and Immunology, Biochemistry, Genetics and Molecular Biology, etc. These findings highlight that there is great potential to conduct research to propagate ocular hygiene to prevent adverse effects of infections.
