Analysis of publication trends in two internationally renowned ophthalmology journals

International journals represent a forum for exchange of current information with contributions from all over the world. High standards are essential. In this report, we compared the publishing trends of two internationally renowned ophthalmology journals--the British Journal of Ophthalmology (BJO) and the American Journal of Ophthalmology (AJO).     

A comparison of scientometric data and publication policies of ophthalmology journals

Purpose:This retrospective database analysis study aims to present the scientometric data of journals publishing in the field of ophthalmology and to compare the scientometric data of ophthalmology journals according to the open access (OA) publishing policies.Methods:The scientometric data of 48 journals were obtained from Clarivate Analytics InCites and Scimago Journal & Country Rank websites. Journal impact factor (JIF), Eigenfactor score (ES), scientific journal ranking (SJR), and Hirsch index (HI) were included. The OA publishing policies were separated into full OA with publishing fees, full OA without fees, and hybrid OA. The fees were stated as US dollars (USD).Results:Four scientometric indexes had strong positive correlations; the highest correlation coefficients were observed between the SJR and JIF (R = 0.906) and the SJR and HI (R = 0.798). However, journals in the first quartile according to JIF were in the second and third quartiles according to the SJR and HI and in the fourth quartile in the ES. The OA articles published in hybrid journals received a median of 1.17-fold (0.15–2.71) more citations. Only HI was higher in hybrid OA; other scientometric indexes were similar with full OA journals. Full OA journals charged a median of 1525 USD lower than hybrid journals.Conclusion:Full OA model in ophthalmology journals does not have a positive effect on the scientometric indexes. In hybrid OA journals, choosing to publish OA may increase citations, but it would be more accurate to evaluate this on a journal basis.

Highly cited publication performance in the ophthalmology category in the Web of Science database: a bibliometric analysis

AIM: To determine and evaluate the features of highly cited articles (HCAs) in the ophthalmology category in the Science Citation Index Expanded (SCI-EXPANDED) from 1991 to 2020. METHODS: The Web of Science Core Collection documents with at least 100 citations from their publication year until December 31, 2020, were evaluated as highly cited. The examined features were the distribution of yearly output and its average number of per publication, HCAs, authors, institutions, journals, and nations. The publication performance of nations and organizations was assessed using six publication indicators. The Y-index was employed to compare the research outputs of various authors. RESULTS: Publications that had cited the most references were highly published in high-impact factor journals. The United States of America came out on top across all six publication indicators, and it was home to eight of the top 10 most productive institutions. The articles written by Breivik et al (2006) and Farrar et al (2001) were highly cited and had a significant impact in 2020. The authors had a higher number of highly cited articles published as corresponding authors than as first authors. CONCLUSION: The findings of the present study highlight the current scope of global research in ophthalmology. The findings can help policy-makers and advisory groups of research centers to develop future policies. In addition, the findings can guide researchers in this field.     

七氟烷联合右美托咪啶对眼科患儿全身麻醉苏醒期躁动的影响

目的：研究七氟烷联合右美托咪啶对眼科患儿全身麻醉苏醒期躁动(EA)的影响。

方法：抽取2018-05/12我院84例择期行眼科手术的患儿为研究对象,随机分为研究组和对照组各42例。均给予吸入七氟烷维持全身麻醉,麻醉插管完成后研究组患儿给予右美托咪啶0.5μg/kg静脉恒速泵注,对照组患儿给予等容量生理盐水。获取苏醒期心率(HR)、平均动脉压(MAP)及血清应激反应指标去甲肾上腺素(NE)、皮质醇(Cor)监测数据,并记录麻醉恢复、EA及并发症发生情况。

结果：对照组患儿清醒时、拔管后1、5、10min的HR、MAP均明显波动,各时点有明显差异(P<0.05),而研究组无差异(P>0.05),且研究组各时点HR、MAP均低于对照组(P<0.05)。研究组患儿清醒时、拔管后10min血清NE、Cor水平均低于对照组(P<0.05)。两组患儿自主呼吸恢复时间、清醒时间无差异(P>0.05),但与对照组相比,研究组患儿拔管时间短,拔管质量评分低(P<0.05)。研究组患儿EA发生率仅12%,低于对照组的31%(P<0.05),EA程度及并发症发生率无差异(P>0.05)。

结论：七氟烷联合右美托咪啶可有效稳定眼科患儿全身麻醉苏醒期血流动力学,减轻应激反应,有效降低EA发生率,且不影响麻醉恢复质量,安全性较高,但需注意过度镇静现象。     

Trends in ophthalmology journals: a five-year bibliometric analysis (2009-2013)

AIM: To explore the trends in the ophthalmic literature over a 5-year period in relation to country, research expenditure and demographics. METHODS: Articles published between 2009 and 2013 by the 20highest-contributing countries in the 20 top-ranked ophthalmology journals were identified by their country of affiliation. The number of articles published and mean impact factor were measured per country for each year and trends explored using regression analysis with 5-year and 10-year forecasts calculated. Data on research expenditure was collected and tested for correlation with the number of articles and mean impact factor. RESULTS: The analysis included 19 338 articles. The USA, UK and Europe accounted for 60.2% of articles published, with the USA contributing 7388 articles (34.0%). The USA also demonstrated the highest mean impact factor (3.5). Research expenditure was significantly correlated with both research output (r=0.86, P<0.001) and scholarly impact (r=0.42, P<0.001). China (P<0.01), Korea (P<0.01) and India (P<0.02) demonstrated a significant growth in research output over the study period. The research contribution of these three countries combined is forecasted to overtake that of Europe within ten years, with China expected to be the second-largest contributor within five years. These countries were also among those demonstrating the greatest growth in research expenditure. CONCLUSION: While the USA and European countries are major contributors of ophthalmic research, the productivity of some Asian countries is growing impressively. The contribution of China, Korea and India is forecasted to outweigh that of Europe by 2023. Research expenditure is highly correlated with research productivity and these trends reflect the differing economic priorities across the world.     

Motivations and future trends: a survey of Canadian ophthalmology residents

BACKGROUND: There has been little investigation into the attitudes and aspirations of current ophthalmology residents. The object of this study was to investigate the factors influencing career choice and to identify the future plans of Canadian ophthalmology residents. METHODS: All ophthalmology residents in English Canadian ophthalmology residency training programs were invited to complete an anonymous survey in June 2006. Data were categorized by demographic variables and basic statistics; chi2 comparative analyses were performed. RESULTS: Of 128 residents surveyed, 49 (38%) responded to the survey. Having the ability to combine medicine and surgery was the most common factor influencing the decision to pursue ophthalmology (98% of respondents), with intellectual stimulation (76%) and mentorship (50%) also emerging as important factors. The majority of residents (62%) plan on pursuing fellowship training, with medical retina, anterior segment/cataract, and cornea being the most popular choices (36%, 34%, and 32%, respectively). Most residents expressed plans of pursuing fellowships abroad, and only 22% planned on training within Canada. Fourteen percent indicated an interest in performing laser refractive surgery, female residents being significantly less likely than males to express such an interest (0% vs. 21%; p < 0.02). Most residents (71%) expressed the wish to practice in an urban or suburban setting, with only 6% intending to work in a rural community. INTERPRETATION: The appeal of the dual medical and surgical nature of ophthalmology is the most common motivating factor for pursuing an ophthalmology residency. The trends identified, including the high level of interest in subspecialty training and the desire to work in an urban setting, have important implications for the future of ophthalmology in Canada.

Citation analysis and journal impact factors in ophthalmology and vision science journals

Citation analysis has evolved over the last 50 years as one parameter for assessing the quality of research published in scientific, technology and social science journals. This is based on the assumption that influential research is widely cited by other scientists and clinicians. With the advent of the Internet, Journal Citation Reports from the Institute for Scientific Information (ISI-JCR) have become widely available to individuals and institutions. In an increasingly competitive research environ-ment, aspects of citation analysis have been suggested as simple proxy, objective measures to evaluate the research quality of a journal, published articles, research institutions and even individual researchers. This review article provides an overview of citation analysis, including definitions, uses of these reports, and related controversies and potential abuses. As it has become the most commonly used indicator, there is a particular focus on the use of the Journal Impact Factor (JIF). This is a widely quoted measure indicating the frequency with which the average article published in a journal of interest will be quoted within a specified time frame that therefore allows approximate comparisons of journals within a particular field of interest. Given the relative paucity of information in this area, emphasis is placed on citation analysis within ophthalmology, in particular in regard to the 43 ophthal-mology, vision science and optometry journals that are listed in the ISI-JCR 2001 reports.     

Diode lasers in ophthalmology

Compact laser emitting diodes of gallium-aluminium-arsenide are now available for incorporation into clinical lasers in ophthalmology. These lasers are cheap and have low running costs. They are portable and their wavelength of emission (810 nm) may be advantageous in certain clinical situations. Clinical trials in retinal vascular disease, trabeculoplasty, and cyclophotocoagulation, have been encouraging. Recent advances allow laser delivery through binocular indirect ophthalmoscopes, endolaser and contact transscleral probes in addition to slit lamp mounted versions. Laser delivery in situations which were previously impossible has immense implications for prevention of blindness due to glaucoma and retinal vascular disease throughout the world.

Performance in the Duke-Elder ophthalmology undergraduate prize examination and future careers in ophthalmology

Aims

Cognitive factors (eg, academic achievement) have had a significant role in selecting postgraduate surgical trainees in the past. This project sought to determine the role of a national undergraduate ophthalmology prize examination (Duke–Elder examination) in the selection of postgraduate ophthalmology trainees. This would also serve as a quality assurance exercise for the assessment, in which the ultimate aim is to encourage trainees into ophthalmology.

Methods

A retrospective analysis of the top 20 ranked candidates in the Duke–Elder examination from 1989 to 2005 (except 1995) was carried out to determine which of them subsequently entered the ophthalmic training and General Medical Council Specialist Registers.

Results

Out of the top 20 candidates in the exam, 29.5% went into specialist training in ophthalmology. Some appeared in the top 20 more than once, with 56% of them going into ophthalmic training, but they had a similar median time to enter training as those who appeared in the top 20 once. There was no significant evidence to suggest that the overall median ranking scores between the UK medical schools differed (P=0.23; Kruskal–Wallis test). However, there was a marked difference in frequency of top 20 candidates from each medical school, which could not be explained by the size of the medical school alone.

Conclusion

It is difficult to conclude from these findings the importance that the Duke–Elder examination has in the selection of trainees into ophthalmology. The role of cognitive factors in selection into postgraduate medical/surgical training is discussed, along with the potential academic criteria, which may influence interview scores.

Undergraduate ophthalmology education survey of New Zealand ophthalmologists, general practitioners and optometrists

Aim : To determine what New Zealand ophthalmologists, general practitioners and optometrists consider important ophthalmic topic areas requiring emphasis in the medical undergraduate curriculum. Method : A total of 793 questionnaires related to the content and teaching of undergraduate ophthalmology were sent to ophthalmologists, general practitioners and optometrists. Results were analysed separately for the three respondent groups and as a whole. Results : Four hundred and fourteen questionnaires were returned (52% return rate). Overall responses of the three participant groups were similar and agreed favourably with the current curriculum. The ability to measure visual acuity (97%) and pupillary reflexes (93%), perform ophthalmoscopy (92%), and assess visual fields (68%) were regarded as ‘important or essential’ by the majority of respondents. Only 53% of respondents consider the ability to diagnose chronic open angle glaucoma as important. The respondents stressed the importance of the diagnosis of predominantly anterior segment disease contrasting with the traditional bias towards the teaching of ophthalmoscopy and posterior segment disease. The majority of respondents stressed the importance of graduating medical students being able to treat bacterial and allergic conjunctivitis, styes, blepharitis, corneal abrasion, and corneal and conjunctival foreign bodies, areas present but not normally emphasized in current curricula. Conclusion : The findings of this study provided additional data to facilitate curriculum design and illustrated the value of an integrated problem‐based learning approach in ophthalmology undergraduate teaching.
