Utilizing a composite citation index for evaluating clinical ophthalmology research: insights into gender, nationality, and self-citation among top ophthalmology researchers.

To compare the performance of a composite citation score (c-score) and its six constituent citation indices, including H-index, in predicting winners of the Weisenfeld Award in ophthalmologic research. Secondary objectives were to explore career and demographic characteristics of the most highly cited researchers in ophthalmology. A publicly available database was accessed to compile a set of top researchers in the field of clinical ophthalmology and optometry based on Scopus data from 1996 to 2021. Each citation index was used to construct a multivariable model adjusted for author demographic characteristics. Using area under the receiver operating curve (AUC) analysis, each index's model was evaluated for its ability to predict winners of the Weisenfeld Award in Ophthalmology, a research distinction presented by the Association for Research in Vision and Ophthalmology (ARVO). Secondary analyses investigated authors' self-citation rates, career length, gender, and country affiliation over time. Approximately one thousand unique authors publishing primarily in clinical ophthalmology/optometry were analyzed. The c-score outperformed all other citation indices at predicting Weisenfeld Awardees, with an AUC of 0.99 (95% CI: 0.97-1.0). The H-index had an AUC of 0.89 (95% CI: 0.83-0.96). Authors with higher c-scores tended to have longer career lengths and similar self-citation rates compared to other authors. Sixteen percent of authors in the database were identified as female, and 64% were affiliated with the United States of America. The c-score is an effective metric for assessing research impact in ophthalmology, as seen through its ability to predict Weisenfeld Awardees.

Effects of low-vision rehabilitation on reading speed and depression in age-related macular degeneration: A systematic review and meta-analysis

Age-related macular degeneration (AMD) is a prevalent eye disease, which can lead to vision loss, impacting daily functioning. This study aimed to evaluate the effect of low-vision rehabilitation techniques such as magnifiers, telescopes, and microperimeter feedback, on improving reading speed and reducing depression in AMD patients. This study is a systematic review and meta-analysis. A systematic search of databases MEDLINE (OVID), EMBASE (OVID), and CINHAL (EBSCO), gray literature including ClinicalTrials.gov and ProQuest Dissertations and Theses Global (ProQuest), Conferences of The Association for Research in Vision and Ophthalmology, American Academy of Ophthalmology, and Canadian Ophthalmological Society were done from inception to 27 July 2022. Fixed-effect and random-effect models were applied to account for heterogeneity between studies. Publication bias was checked through funnel plots. A total of 33 studies (2611 subjects) were included;14 studies were included in the meta-analysis (1123 subjects) and 19 were included in the qualitative analysis. We found a non-significant increase in reading speed (effect size [ES] = 0.02, 95% confidence interval [CI] = [−0.18, 0.23]) for studies comparing patients who received no low-vision rehabilitation, versus the intervention group of AMD patients who received low-vision rehabilitation. We also found a significant decrease in reading speed (ES = −0.92, 95% CI = [−1.46, −0.39]) between studies evaluating the difference in reading speed at baseline visits compared to the follow-up visits in AMD patients who received low-vision rehabilitation. Low-vision rehabilitation was also found to result in a decrease in depression severity when compared to control groups, as well as from initial assessment to subsequent follow-up visits. Individuals with AMD who engaged in low-vision rehabilitation demonstrated improved reading speeds compared to their own baseline and to those who did not receive any interventions. Furthermore, these interventions also contributed to a reduction in symptoms of depression.

Retinal Development in Infants and Young Children With Albinism: Evidence for Plasticity in Early Childhood

Presented at the 2016 Association for Research in Vision and Ophthalmology meeting and at the 2015 British Isles Paediatric, Ophthalmology and Strabismus Association meeting. To investigate the time course of foveal development after birth in infants with albinism. Prospective, comparative cohort optical coherence tomography study. Thirty-six children with albinism were recruited. All participants were between 0 and 6 years of age and were seen at Leicester Royal Infirmary. A total of 181 mixed cross-sectional and longitudinal optical coherence tomography examinations were obtained, which were analyzed for differences in retinal development in comparison to 297 cross-sectional control examinations. Normal retinal development involves migration of the inner retinal layers (IRLs) away from the fovea, migration of the cone photoreceptors into the fovea, and elongation of the outer retinal layers (ORLs) over time. In contrast to controls where IRL migration from the fovea was almost completed at birth, a significant degree of IRL migration was taking place after birth in albinism, before arresting prematurely at 40 months postmenstrual age (PMA). This resulted in a significantly thicker central macular thickness in albinism (Δ=83.8 ± 6.1, P < .0001 at 69 months PMA). There was evidence of ongoing foveal ORL elongation in albinism, although reduced in amplitude compared with control subjects after 21 months PMA (Δ=-17.3 ± 4.3, P < .0001). We have demonstrated evidence of ongoing retinal development in young children with albinism, albeit at a reduced rate and magnitude compared with control subjects. The presence of a period of retinal plasticity in early childhood raises the possibility that treatment modalities, which aim to improve retinal development, could potentially optimize visual function in albinism.

Japan to Global Eye Genetics Consortium: Extending Research Collaboration for Inherited Eye Diseases.

Japan Eye Genetics Consortium (JEGC) was established in 2011 to migrate research system to all-Japan structure for collecting phenotype-genotype information for inherited retinal diseases and other retinal diseases including hereditary optic neuropathy and hereditary glaucoma. Diagnostic team was assembled to maintain quality of diagnostic and to collect phenotype information to database in Tokyo Medical Center (TMC). Over the past 10 years, 1538 pedigree [2788 deoxyribonucleic acid (DNA) samples] was collected from 38 ophthalmology departments and eye hospitals. Whole exome analysis has improved diagnostic rate from ~17% in 2011 to 53% in 2021, with 27% of known variants, 18% of novel variants in known gene, 8% of potential novel disease-causing genes, and 47% of pedigree with unknown cause. Approximately 70% of Japanese patients were affected by novel mutation or by unknown cause. In 2014, Asian Eye Genetics Consortium (AEGC) was established by researchers from Hong Kong, India, Japan, and the US, later renamed to Global Eye Genetics Consortium (GEGC) to expand the idea of collaborative research on rare genetic eye diseases in Asia, Middle East, Africa, and South America. GEGC phenotype-genotype database, GenEye, was constructed to collect and catalog genetic eye diseases at global scale. Over 200 members from 30 countries, GEGC now has 200 members from 30 continents, performing scientific programs, young investigator visiting program, and GEGC organized session at the meetings of the Asia-Pacific Academy of Ophthalmology (APAO), The Association for Research in Vision and Ophthalmology (ARVO), All India Ophthalmological Society (AIOS), World Ophthalmology Congress (WOC), and International Society for Eye Research (ISER).

In Through the Out Door: Editas' CEOs Grasp Opportunities Amidst Challenges

In Through the Out Door: Editas' CEOs Grasp Opportunities Amidst Challenges

Tribology and the Ocular Surface.

IntroductionTribology is known as the science of friction, lubrication and the determination of what occurs when two surfaces slide against one another. The required partners in this science are a minimum of two surfaces and relative motion. Tribology could be a key factor in dissecting the issues that surround and confound dry eye in patients as well as contact lens discomfort and intolerance. Specifically, it is this issue that is a potential causative underlying factor that could lead to conditions like lid wiper epitheliopathy (LWE).MethodsPeer-reviewed literature was reviewed as It pertains to ocular tribology and the application to the ocular anatomy. A PubMed review was performed using the keywords: tribology, friction, lid wiper epitheliopathy, contact lens, and dry eye. All manuscripts were reviewed for mentions of tribology and friction. The exact same process was performed with The Association for Research in Vision and Ophthalmology (ARVO) abstracts.ResultsIn relation to the ocular surface, tribology describes the mechanical interactions between the upper and lower lid wipers and the globe. The Stribeck curve can be applied, as the sliding partners are separated by a complex, lubricating tear film. The surface brush anatomy at the eye to eyelid juncture reduces friction and alters the Stribeck curve in favor of the hydrodynamic regime, allowing for high velocity movement with minimal wear. Changes to the tear film or the introduction of a contact lens can displace the Stribeck curve, increase friction, and induce wear thus leading to patient symptomology.ConclusionFurther studies may provide new insight into contact lens discomfort and ocular surface disease, including LWE; however, adaptation of tribology work performed in vitro to in vivo patient care is challenging.

Shared Care and Virtual Clinics for Glaucoma in a Hospital Setting.

Glaucoma patients require lifelong management, and the prevalence of glaucoma is expected to increase, resulting in capacity problems in many hospital eye departments. New models of care delivery are needed to offer requisite capacity. This review evaluates two alternative schemes for glaucoma care within a hospital, i.e., shared care (SC) and virtual clinics (VCs), whereby non-medical staff are entrusted with more responsibilities, and compares these schemes with the “traditional” ophthalmologist-led outpatient service (standard care). A literature search was conducted in three large bibliographic databases (PubMed, Embase, and Trip), and the abstracts from the prior five annual meetings of the Association for Research in Vision and Ophthalmology were consulted. Twenty-nine were included in the review (14 on SC and 15 on VCs). Patients with low risk of vision loss were considered suitable for these approaches. Among the non-medical staff, optometrists were the most frequently involved. The quality of both schemes was good and improved with the non-medical staff being trained in glaucoma care. No evidence was found on patients feeling disadvantaged by the lack of a doctor visit. Both schemes increased the hospital’s efficiency. Both SC and VCs are promising approaches to tackle the upcoming capacity problems of hospital-based glaucoma care.

Diagnostic accuracy of current machine learning classifiers for age-related macular degeneration: a systematic review and meta-analysis.

The objective of this study was to systematically review and meta-analyze the diagnostic accuracy of current machine learning classifiers for age-related macular degeneration (AMD). Artificial intelligence diagnostic algorithms can automatically detect and diagnose AMD through training data from large sets of fundus or OCT images. The use of AI algorithms is a powerful tool, and it is a method of obtaining a cost-effective, simple, and fast diagnosis of AMD. MEDLINE, EMBASE, CINAHL, and ProQuest Dissertations and Theses were searched systematically and thoroughly. Conferences held through Association for Research in Vision and Ophthalmology, American Academy of Ophthalmology, and Canadian Society of Ophthalmology were searched. Studies were screened using Covidence software and data on sensitivity, specificity and area under curve were extracted from the included studies. STATA 15.0 was used to conduct the meta-analysis. Our search strategy identified 307 records from online databases and 174 records from gray literature. Total of 13 records, 64,798 subjects (and 612,429 images), were used for the quantitative analysis. The pooled estimate for sensitivity was 0.918 [95% CI: 0.678, 0.98] and specificity was 0.888 [95% CI: 0.578, 0.98] for AMD screening using machine learning classifiers. The relative odds of a positive screen test in AMD cases were 89.74 [95% CI: 3.05-2641.59] times more likely than a negative screen test in non-AMD cases. The positive likelihood ratio was 8.22 [95% CI: 1.52-44.48] and the negative likelihood ratio was 0.09 [95% CI: 0.02-0.52]. The included studies show promising results for the diagnostic accuracy of the machine learning classifiers for AMD and its implementation in clinical settings.

Crossing the Death Valley of publication process in cornea and ocular surface diseases: from abstracts presented at the Association for Research in Vision and Ophthalmology annual meeting to full-text manuscripts.

This study was conducted to analyze the profile and publication rate of abstracts in indexed journals presented in the cornea section at the Association for Research in Vision and Ophthalmology Annual Meeting and to further identify potential predictive factors for better outcomes. Abstracts accepted for presentation at the 2013 Association for Research in Vision and Ophthalmology Annual Meeting in the cornea section were sought via PubMed and Scopus to identify whether they had been published as full-text manuscripts. First author's name, time of publication, journal's name, and impact factor were recorded. A multivariate regression was performed to explore the association between variables and both the likelihood of publication and the journal's impact factor. A Kaplan-Meier analysis was performed to evaluate the time course of publication of abstracts. Of the 939 analyzed abstracts, 360 (38.3%) were published in journals with a median impact factor of 3.4. The median time interval between abstract submission and article publication was 22 months. The multivariate analysis revealed that abstracts were more likely to be published if they were funded (OR=1.482, p=0.005), had a control group (OR=1.511, p=0.016), and had a basic science research scope (OR=1.388, p=0.020). The journal's impact factor was higher in funded studies (β=0.163, p=0.002) but lower in multicenter studies (β=-0.170, p=0.001). The Kaplan-Meier analyses revealed significant differences in the publication time distribution for basic science vs clinical abstracts (χ2=7.636), controlled vs uncontrolled studies (χ2=6.921), and funded vs unfunded research (χ2=13.892) (p<0.05). Almost 40% of Association for Research in Vision and Ophthalmology abstracts were published within 5 years from submission. Funding support, basic research scope, and controlled design were the determinants of better outcomes of publication.

MAP4K4 is Involved in the Neuronal Development of Retinal Photoreceptors

Differentiated from multipotent neural progenitors, the development of retinal photoreceptors is under sophisticated programming of multiple genes. Mitogen-activated protein kinase kinase kinase kinase-4 (MAP4K4) is one of the upstream regulators in the mitogen-activated protein kinase (MAPK) signaling pathway, associated to neurodegeneration. However the role of MAP4K4 in retina—an extension of neural system—remains unknown. In the present study, we generated knockout models of C57BL/6j mice in vivo and 661W cells in vitro to unfold the mechanism of MAP4K4 during neuronal development of retinal photoreceptors. We identified the linkage between the Map4k4 ablation induced murine homozygous lethality and neural tube malformation during the embryonic phase from EM9.5 to EM10.5, providing a collateral evidence for the involvement of MAP4K4 in early stage embryonic neural formation. To further clarify the participation of MAP4K4 in neurogenesis of photoreceptors, we subjected 661W cells of both Map4k4 +/+ and Map4k4 -/- to staurosporine. Later, spatiotemporal development and remodeling of photoreceptor cells were detected. Ablation of Map4k4 leaded to vulnerability of photoreceptor nerites during induced neuronal development. By monitoring transcriptional and protein variation of MAPK signaling pathway targeted factors, we discovered the imbalanced neurogenesis factors occurring in Map4k4 -/- cells. MAP4K4 promoted jun proto-oncogene (c-JUN) phosphorylation and recruited other factors related to nerve growth, convoying the photoreceptors to robust formation of neurites. Together, MAP4K4 showed decisiveness in the programming fate of retinal photoreceptors through molecular modulations, which may be providing a new insight into the blueprint of visual formation.

THE ANGIOPOIETIN/TIE PATHWAY IN RETINAL VASCULAR DISEASES: A Review.

To provide a concise overview for ophthalmologists and practicing retina specialists of available clinical evidence of manipulating the angiopoietin/tyrosine kinase with immunoglobulin-like and endothelial growth factor-like domains (Tie) pathway and its potential as a therapeutic target in retinal vascular diseases. A literature search for articles on the angiopoietin/Tie pathway and molecules targeting this pathway that have reached Phase 2 or 3 trials was undertaken on PubMed, Association for Research in Vision and Ophthalmology meeting abstracts (2014-2019), and ClinicalTrials.gov databases. Additional information on identified pipeline drugs was obtained from publicly available information on company websites. The PubMed and Association for Research in Vision and Ophthalmology meeting abstract search yielded 462 results, of which 251 publications not relevant to the scope of the review were excluded. Of the 141 trials related to the angiopoietin/Tie pathway on ClinicalTrials.gov, seven trials focusing on diseases covered in this review were selected. Vision/anatomic outcomes from key clinical trials on molecules targeting the angiopoietin/Tie pathway in patients with retinal vascular diseases are discussed. Initial clinical evidence suggests a potential benefit of targeting the angiopoietin/Tie pathway and vascular endothelial growth factor-A over anti-vascular endothelial growth factor-A monotherapy alone, in part due to of the synergistic nature of the pathways.

The transition of ARVO journals to open access

Key points In January 2016, the three journals of the Association for Research in Vision and Ophthalmology (ARVO) transitioned to gold open access. Increased author charges were introduced to partially offset the loss of subscription revenue. Submissions to the two established journals initially dropped by almost 15% but have now stabilized. The transition has not impacted acceptance rates and impact factors, and article pageviews and downloads may have increased as a result of open access.

Ocular manifestations in SARS-CoV-2 positive patients: a systematic review

ABSTRACT Objective: Investigate the importance of optical symptoms within SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) patients.Design: Systematic reviewMethods: Databases searched included Medline, EMBASE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Clinicaltrials.gov, ProQuest. As well, meeting abstracts from American Academy of Ophthalmology, Association for Research in Vision and Ophthalmology and Canadian Ophthalmological Society were also considered. Articles underwent two rounds of screening before risk of bias assessment and data extraction.Results: In total, 582 studies were identified. A total of 2064 unique SARS-CoV-2 positive patients are included in this review from 13 different studies that met the inclusion criteria. We observed that the most common ocular symptoms in patients with SARS-CoV-2 were dry eyes, chemosis, epiphora, and blurred vision. The least common symptoms included hyperemia, conjunctivitis and photophobia. Additionally, we observed a unique relationship between patients with ocular manifestations and the severity of the systemic symptoms.Conclusion: Ocular symptoms do not occur commonly among SARS-CoV-2 positive patients; however, this study displays that there is an occurrence of common ocular manifestations such as dry eyes, chemosis, epiphora, and blurred vision. Therefore, increased ocular examinations may aid in diagnosis of SARS-CoV-2 infections.ABBREVIATIONS: COVID-19 (coronavirus disease 2019), SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2)
