Vision impairment and blindness in individuals aged 60 years and older in Latin America and the Caribbean / Discapacidad visual y ceguera en personas mayores de 60 años en América Latina y el Caribe / Deficiência visual e cegueira em indivíduos com 60 anos ou mais na América Latina e no Caribe

[ABSTRACT]. Objective. To determine the prevalence and causes of vision loss and calculate the effective cataract surgery coverage (eCSC) in adults aged 60 years and older in Latin America and the Caribbean in 2020. Methods. The International Agency for the Prevention of Blindness Vision Atlas and the Rapid Assessment of Avoidable Blindness databases were used as data source. The collected data were used to estimate the prevalence and causes of vision loss in people aged 60 years and older, and to determine the eCSC. Results. The overall prevalence of moderate to severe vision impairment (MSVI) and blindness in Latin America and the Caribbean were 14.14% and 2.94%, respectively. Tropical Latin America was the subregion with the highest prevalence of blindness (3.89%) while Southern Latin America had the lowest (0.96%). For both MSVI and blindness, cataract was the main cause of vision loss. The eCSC rates showed great variation, ranging from 4.0% in Guatemala to 75.2% in Suriname. Conclusions. The prevalence of vision loss in adults aged 60 years and older in Latin America and the Caribbean was higher than previous estimates on younger groups. Cataract was the main cause of blindness, and the eCSC indicates that the outcomes from cataract surgery should be improved. Specific actions associated with improving access, integrating eye assessment with primary care programs, expanding the use of telemedicine, and improving data quality should be taken by public health authorities aiming to address vision loss in this group.

Learning curves of novice residents on cataract surgery simulator: the E3CAPS pedagogic study.

INTRODUCTION: Training novice ophthalmology residents on the EyeSi® simulator increases cataract surgery safety. However, there is no consensus regarding how much training residents should perform before their first time on patients. We evaluated the French national training program through the analysis of the learning curves of novice residents. METHODS: This prospective multicentric pedagogic study was conducted with French novice residents. Each resident completed the recommended four two-hour training sessions and performed a standardized assessment simulating standard cataract surgery before the first session (A0), at the end of the first (A1), second (A2), third (A3) and fourth (A4) sessions. For each surgical step of each attempt, the following data were collected: score, odometer, completion time, posterior capsular rupture and cumulative energy delivered (ultrasounds) during phacoemulsification. A performance threshold was set at a score of 80/100 for each surgical step, 400/500 for the overall procedure. Only descriptive statistics were employed. RESULTS: Sixteen newly nominated ophthalmology residents were included. Median score progressively increased from 95 [IQR 53; 147]) at A0 to 425 [IQR 411; 451] at A4. Despite a significant progression, the "emulsification" step had the lowest A4 scores 86 [IQR 60; 94] without reduction in completion time, odometer or ultrasounds delivered. The rate of posterior capsular rupture decreased linearly from 75% at A0 to 13% at A4 during "emulsification" and from 69 to 0% during "irrigation and aspiration". At A4, only 25% [8; 53] of residents had > 80 at each step and only 75% [47; 92] had > 400/500 overall. CONCLUSION: A training program consisting of four two-hour sessions on the EyeSi simulator over four consecutive days effectively enhances the surgical skills of novice ophthalmology residents. Undergoing more training sessions may improve scores and decrease the incidence of surgical complications, particularly at the emulsification step of cataract surgery. The learning curves presented here can reassure residents who are progressing normally and help identify those who need a further personalized training program.  TRIAL REGISTRATION: ClinicalTrials registration number: NCT05722080 (first submitted 22/12/2022, first posted 10/02/2023).

[Comparison and analysis of ophthalmic resources and service ability in Shanxi Province in 2014 and 2021].

Objective: To compare and analyze the ophthalmic resources and service ability in Shanxi Province in 2014 and 2021, and to provide reference for the development planning of ophthalmology and eye care. Methods: In this cross-sectional study, a questionnaire survey was conducted among all ophthalmic institutions registered in the health administrative department in 11 cities of Shanxi Province by the end of 2014 and 2021 by using the National Ophthalmology Competency Resource Questionnaire (compiled by the Medical Administration and Hospital Authority of the National Health and Wellness Commission). The basic situations of ophthalmic institutions in 2014 and 2021, as well as the human resources, ophthalmic equipment configuration, technology and medical service capabilities, were recorded and compared. The chi-square test was used for statistical analysis. Results: A total of 270 questionnaires for 2014 were collected from 270 ophthalmic institutions, and 292 questionnaires for 2021 from 292 ophthalmic institutions. The institution categories in 2014 (197 general hospitals, 31 eye hospitals and 42 others) were statistically different from those in 2021 (182 general hospitals, 45 eye hospitals and 65 others) (P<0.05). The proportion of doctors with senior titles in ophthalmic institutions increased from 25.5% (346/1 358) in 2014 to 41.7% (580/1 391) in 2021, the proportion of senior technicians increased from 9.4% (14/148) to 25.3% (110/435), the proportion of doctors with junior titles decreased from 42.1% (572/1 358) to 26.5% (369/1 391), and the proportion of junior technicians decreased from 45.3% (67/148) to 39.1% (170/435). There was a significant difference in the distribution of professional titles between doctors and technicians in ophthalmic institutions (P<0.05). The number of doctors (130 to 28), nurses (152 to 50), technicians (33 to 11) and full-time optometrists (44 to 12) in the first-class ophthalmic institutions decreased, the increase of equipment with the ophthalmic A-ultrasound scan system, fundus camera and coherent optical tomography system (35.1%, 28.9% and 25.4%; P<0.05) ranked the top three, and the increase of performing the phacoemulsification procedure, intraocular lens implantation, intravitreal injection and iris surgery (30.2%, 24.7% and 20.7%; P<0.05) ranked the top three in 2021 as compared to 2014. Conclusions: The resources and service ability of ophthalmology in Shanxi Province developed in 2021 in comparison with 2014. However, there were some problems, such as changes in the type and structure of eye institutions, unreasonable proportions of professional titles, insufficient human resources in primary ophthalmic institutions, and slow improvement in the allocation of ophthalmology equipment and technical capabilities.

Physician-to-Physician eConsultations to Ophthalmologists at an Academic Medical Center.

Purpose: Physician-to-physician electronic consultation (eConsults) are used across specialties; however, their effectiveness in ophthalmology has not been reported. This study evaluated the feasibility and diagnostic accuracy of a physician-to-physician ophthalmology eConsult program, assessed the timeliness of in-person evaluation, and characterized the clinical questions of non-ophthalmology providers. Methods: Retrospective review of patients for whom an ophthalmology eConsult was placed to Massachusetts Eye and Ear from February 2019-August 2021. The eConsults were reviewed to identify submission-to-response time, primary diagnoses by eConsultant, and referral outcomes. The eConsults were categorized based on clinical question, urgency, and ophthalmic condition addressed. Demographic data on patients and referring providers were collected. Results: One hundred ophthalmology eConsults were placed, and 100% were responded to by an ophthalmologist. An average of 1.6 ± 1.9 days elapsed from the time of eConsult to completion. Of the 30 patients who presented for in-person evaluation at an ophthalmology clinic, diagnostic concordance between eConsultant and in-person ophthalmologist was observed in 93% of cases (n = 28 of 30). An average of 28.9 ± 27.4 days from eConsult response to in-person follow-up was observed. The most common clinical inquiries were about appropriate triage/referral (24.4%), management (22%), and diagnosis (19.7%). All eConsults were non-urgent. The most common ophthalmic condition addressed was chalazia/hordeola (14%). Only 5% of patients presented to an emergency department for the same ophthalmic concern addressed by eConsult. Conclusions: Ophthalmology eConsults provide timely access to nonurgent ocular diagnosis, triage, and management and in our study seem to provide high rates of diagnostic accuracy for nonurgent ophthalmic conditions. Translational Relevance: Using ophthalmic eConsults can facilitate timely access to specialty care and reduce patient and provider burden.

Enhancing ophthalmology medical record management with multi-modal knowledge graphs.

The electronic medical record management system plays a crucial role in clinical practice, optimizing the recording and management of healthcare data. To enhance the functionality of the medical record management system, this paper develops a customized schema designed for ophthalmic diseases. A multi-modal knowledge graph is constructed, which is built upon expert-reviewed and de-identified real-world ophthalmology medical data. Based on this data, we propose an auxiliary diagnostic model based on a contrastive graph attention network (CGAT-ADM), which uses the patient's diagnostic results as anchor points and achieves auxiliary medical record diagnosis services through graph clustering. By implementing contrastive methods and feature fusion of node types, text, and numerical information in medical records, the CGAT-ADM model achieved an average precision of 0.8563 for the top 20 similar case retrievals, indicating high performance in identifying analogous diagnoses. Our research findings suggest that medical record management systems underpinned by multimodal knowledge graphs significantly enhance the development of AI services. These systems offer a range of benefits, from facilitating assisted diagnosis and addressing similar patient inquiries to delving into potential case connections and disease patterns. This comprehensive approach empowers healthcare professionals to garner deeper insights and make well-informed decisions.

Binocular vision parameters and visual performance in bilateral keratoconus corrected with spectacles versus rigid gas-permeable contact lenses / Parámetros de visión binocular y rendimiento visual en queratocono bilateral corregido con gafas versus lentes de contacto rígidos permeables al gas

Purpose: To analyze binocular vision of individuals aged 18 to 35 years diagnosed with keratoconus, utilizing spectacles and rigid gas-permeable (RGP) contact lenses. Research was led by the Universidad Autónoma de Aguascalientes, México and Fundación Universitaria del Área Andina Pereira, Colombia. Methods: A single center, prospective non-randomized, comparative, interventional, open-label study, in which the differences in binocular vision performance with both spectacles and RGP contact lenses was carried out from December 2018 to December 2019. Sampling was performed according to consecutive cases with keratoconus that met the inclusion criteria until the proposed sample size was reached. Results: Rigid gas-permeable (RGP) contact lenses notably enhanced distance and near visual acuity in keratoconus patients compared to spectacles. Visual alignment analysis shows exophoria at both distances and is slightly higher with RGP contact lenses. The difference was statistically significant (p<0.05), with 82.5 % presenting compensated phoria with spectacles and pnly 42.50% with RGP contact lenses. Stereoscopic vision improved while wearing RGP contact lenses (42.59 %), although accommodation and accommodative flexibility remained within normal ranges. Conclusions: Patients with keratoconus fitted with RGP contact lenses have improved binocular vision skills such as visual acuity, stereopsis, and accommodative flexibility. However, even when the vergence and motor system is decompensated with respect to normal ranges, the range between break and recovery points for both fusional reserves and the near point of convergence (NPC) improves with the use of RGP contact lenses, giving indications of an adaptive condition of the motor system from the medium to the long term.(AU)

Management of COVID-19 in Ophthalmology.

From its outbreak in early 2020, the new SARS-CoV-2 infection has deeply affected the entire eye care system for several reasons. Since the beginning of the COVID-19 pandemic, ophthalmologists were among the "high-risk category" for contracting the SARS-CoV-2 infection based on the notion that the eye was suspected to be a site of inoculation, infection, and transmission. Clinical ophthalmologists have been required to learn and promptly recognize the ocular manifestations associated with the COVID-19 disease, with its treatments and vaccinations. Restriction measures, lockdown periods, guidelines to prevent SARS-CoV-2 infection transmission, and the use of telemedicine and artificial intelligence modalities have induced profound modifications. These changes, which are most likely to be irreversible, influence routine clinical practice, education, and research, thus giving rise to a "new ophthalmology in the COVID era". This book chapter aims to provide several notions regarding COVID-19 in ophthalmology, including the SARS-CoV-2 virus infection and transmission modalities; the ocular manifestation associated with the COVID-19 disease; the drugs and vaccines used for COVID-19; the precautions adopted in the ophthalmic practice to limit the spread of the virus; the consequences of the pandemic on the ophthalmic patients, clinicians, and the entire eye care system; and, the future of ophthalmology in the era of "COVID new normal".

Thiel cadaver eye as a training model for sub-Tenon's blocks: a feasibility study.

BACKGROUND: Regional anaesthesia education, especially for ocular procedures, necessitates reliable surgical training models. While cadaveric models offer anatomical fidelity, conventional embalming methods may compromise tissue integrity. We aimed to assess the effectiveness of Thiel cadavers for training in sub-Tenon's blocks by evaluating ocular tissues and measuring insertion forces. METHODS: Experimental design, using twenty eyes from ten Thiel cadaver heads. These cadavers were specifically prepared to test the administration of sub-Tenon's blocks. The research was conducted in a controlled laboratory setting appropriate for handling cadaveric materials and conducting precise measurements. Each cadaver eye underwent an initial ultrasound examination, and its axial length was noted. An intravitreal injection of heptastarch solution followed, to re-establish the eye's sphericity. After this volume injection, the axial length and intraocular pressure were measured again. Mock sub-Tenon's blocks were administered in 2 separate quadrants of the eye, with insertion forces measured using a pressure gauge. These were compared to a data set of insertion forces measured in a series of isolated pig's eyes on which STBs had been performed. Main outcome measurements were macroscopic assessment of the ocular tissue layers and the insertion forces required for the sub-Tenon's blocks. In a second set of 10 Thiel cadaver heads, 5 ml of sodium chloride were injected as sub-Tenon's blocks and the emergence of a periocular "T-sign" ascertained and measured by ultrasound. RESULTS: Four of twenty eyes (20%) retained near-natural sphericity, with the remaining requiring volume injection to approximate physiological shape and pressure. The conjunctiva and Tenon's layer were intact, and correct cannula placement was achieved in all cases. In 16 of 20 eyes where T-signs could be measured, the median thickness of the T-sign amounted to 2.72 mm (range 1.34 mm-5.28 mm). The average maximum cannula insertion force was 2.92 Newtons. Insertion forces in intact Thiel cadaver heads were consistently higher than in isolated pig's eyes (3.6 N vs 2.0 N). CONCLUSION: These findings suggest that Thiel cadavers are a promising model for training in sub-Tenon'sblocks, despite the challenge of often desiccated and involuted eyes.

Advancements and emerging trends in ophthalmic anti-VEGF therapy: a bibliometric analysis.

INTRODUCTION: Vascular Endothelial Growth Factor (VEGF) is associated with abnormal fundus neovascularization. Consequently, Anti-VEGF agents are vital for ophthalmic treatment. This paper reviews the application of anti-VEGF agents in ophthalmology over the past two decades with the aim of providing insights for further research. METHODS: A meticulous search strategy was employed in the Web of Science Core Collection literature from 2003 to 2023 to gather relevant literature, which was then analyzed using VOSviewer, CiteSpace, and the R package Bibliometrix. RESULTS: The study included 3,602 publications from 83 countries and 3,445 institutions. The United States and China have emerged as leading contributors in terms of the publication volume. Johns Hopkins University, the University of Sydney, and Genentech Inc were identified as frontrunners in this field. "Retina" had the highest publication volume, whereas "Ophthalmology" had the highest citation frequency. Among the 15,918 scholars, Bressler NM, Holz FG, Glassman AR, and Bandello F led in publication volume, while Brown DM was the most cited author. High-frequency keywords included "Endothelial Growth Factor," "Therapy," "Safety," and "Randomized Clinical Trial." CONCLUSION: Anti-VEGF drugs have shown notable success in treating neovascular eye diseases, especially wet age-related macular degeneration and diabetic macular edema, focusing on clinical efficacy, injection regimens, and safety. Future directions include developing new anti-VEGF drugs, drug delivery systems, non-invasive administration, multi-target drugs, leveraging big data and artificial intelligence, and addressing the current treatment limits. Continuous innovation and method improvement in this field promise more breakthroughs, providing effective, safe, and economical options for eye disease treatment.

Running the enrollment numbers on ophthalmic clinical trials in the United States.

SIGNIFICANCE: This is one of the first reports to summarize the enrollment metrics for ophthalmology trials completed in the United States (US). PURPOSE: This study aimed to describe US ophthalmology clinical trial enrollment metrics to facilitate planning and budgeting of US Food and Drug Administration-regulated ophthalmological drugs trials. METHODS: A GlobalData PLC search was conducted on or before February 27, 2024, to evaluate the clinical trial landscape for completed ophthalmology clinical trials conducted in the US. The primary search contained only the term "ophthalmology," which was restricted to trials that were completed and were conducted within the US. Trials were classified as multicenter when trials included three sites or more, and when the enrollment search resulted in ≥30 multicenter trials for an individual indication, enrollment data were further broken down by Food and Drug Administration trial phase. RESULT: The search yielded 2229 trials, which analyzed 980 different drugs produced by 854 different sponsors. The most common indications evaluated in US trials were macular degeneration, glaucoma, macular edema, allergies, and keratoconjunctivitis. Multicenter trials by indication had an overall median enrollment period range of 4.8 to 35.1 months; number of subjects enrollment, range of 36 to 518 subjects; number of sites utilized, range of 4 to 74 sites; and enrollment rate, range of 0.11 to 4.04 subjects/sites per month. There were 17 indications with ≥30 multicenter trials, which allowed for enrollment metric calculation by trial phase. CONCLUSIONS: This study provides sponsors with an understanding of the number of subjects and sites needed to complete a trial while also setting realistic enrollment timelines. Although this work represents the US market, more work is needed to better understand other countries given that country-specific guidelines and subject beliefs may impact enrollment metrics.

Bibliometric analysis of ophthalmic OCT and OCT angiography research trends over the past 20 years.

PURPOSE: Optical coherence tomography (OCT) and OCT angiography (OCTA) are widely used in the diagnosis of ophthalmic diseases. This study aims to provide a comprehensive bibliometric analysis of ophthalmologic OCT and OCT angiography. METHODS: We retrieved publications on ophthalmic OCT and OCTA from 2003 to 2022 from the Web of Science Core Collection and used bibliometric tools to analyze and visualize the distribution, trend, and hotspots. RESULTS: In total, 20,817 articles written by 48,160 authors from 106 countries were selected. The number of publications has significantly increased. In the last two decades, the USA was the most productive country and received the highest citations. The most productive journal was Investigative Ophthalmology and Visual Science and received the highest number of citations. Moorfields Eye Hospital was the most productive institution. Bandello F published the most papers, while Spaide RF was the highest cited author. SPAIDE RF, 2011, AM J Ophthalmology was the most cited document. "OCT", "glaucoma" and "OCTA" were three hotspots in the last two decades. "Vessel density" and "deep learning" would be research hotspots in the future. CONCLUSION: The bibliometric analysis of ophthalmic OCT and OCTA research over the past two decades on keywords, authors, citations, hotspots and trends will provide global researchers with valuable information for future research and cooperation.

[Alexey Alexeevich Maklakov (19.09.1872-21.03.1918)]. / Aleksei Alekseevich Maklakov (19.09.1872­21.03.1918).

This article commemorates the 150th anniversary of the birth of prominent early 20th-century Russian ophthalmologist Professor Alexey Alekseevich Maklakov of Moscow University and aims to explore his biography, which remains relatively obscure. His scientific, pedagogical, and public activities have not been subjected to comprehensive analysis until now. The study clarifies key dates in his life through examination of archival documents.

Towards Standardizing Ophthalmic Data for Seamless Interoperability in Eye Care.

INTRODUCTION: Seamless interoperability of ophthalmic clinical data is beneficial for improving patient care and advancing research through the integration of data from various sources. Such consolidation increases the amount of data available, leading to more robust statistical analyses, and improving the accuracy and reliability of artificial intelligence models. However, the lack of consistent, harmonized data formats and meanings (syntactic and semantic interoperability) poses a significant challenge in sharing ophthalmic data. METHODS: The Health Level 7 (HL7) Fast Healthcare Interoperability Resources (FHIR), a standard for the exchange of healthcare data, emerges as a promising solution. To facilitate cross-site data exchange in research, the German Medical Informatics Initiative (MII) has developed a core data set (CDS) based on FHIR. RESULTS: This work investigates the suitability of the MII CDS specifications for exchanging ophthalmic clinical data necessary to train and validate a specific machine learning model designed for predicting visual acuity. In interdisciplinary collaborations, we identified and categorized the required ophthalmic clinical data and explored the possibility of its mapping to FHIR using the MII CDS specifications. DISCUSSION: We found that the current FHIR MII CDS specifications do not completely accommodate the ophthalmic clinical data we investigated, indicating that the creation of an extension module is essential.

Ethical considerations for large language models in ophthalmology.

PURPOSE OF REVIEW: This review aims to summarize and discuss the ethical considerations regarding large language model (LLM) use in the field of ophthalmology. RECENT FINDINGS: This review of 47 articles on LLM applications in ophthalmology highlights their diverse potential uses, including education, research, clinical decision support, and surgical assistance (as an aid in operative notes). We also review ethical considerations such as the inability of LLMs to interpret data accurately, the risk of promoting controversial or harmful recommendations, and breaches of data privacy. These concerns imply the need for cautious integration of artificial intelligence in healthcare, emphasizing human oversight, transparency, and accountability to mitigate risks and uphold ethical standards. SUMMARY: The integration of LLMs in ophthalmology offers potential advantages such as aiding in clinical decision support and facilitating medical education through their ability to process queries and analyze ophthalmic imaging and clinical cases. However, their utilization also raises ethical concerns regarding data privacy, potential misinformation, and biases inherent in the datasets used. Awareness of these concerns should be addressed in order to optimize its utility in the healthcare setting. More importantly, promoting responsible and careful use by consumers should be practiced.
