[PMID: 38464369 PMCID: PMC10921172 DOI: 10.4239/wjd.v15.i2.251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 12/10/2023] [Accepted: 01/12/2024] [Indexed: 02/04/2024] Open
Abstract
BACKGROUND Early screening and accurate staging of diabetic retinopathy (DR) can reduce blindness risk in type 2 diabetes patients. DR's complex pathogenesis involves many factors, making ophthalmologist screening alone insufficient for prevention and treatment. Often, endocrinologists are the first to see diabetic patients and thus should screen for retinopathy for early intervention. AIM To explore the efficacy of non-mydriatic fundus photography (NMFP)-enhanced telemedicine in assessing DR and its various stages. METHODS This retrospective study incorporated findings from an analysis of 93 diabetic patients, examining both NMFP-assisted telemedicine and fundus fluorescein angiography (FFA). It focused on assessing the concordance in DR detection between these two methodologies. Additionally, receiver operating characteristic (ROC) curves were generated to determine the optimal sensitivity and specificity of NMFP-assisted telemedicine, using FFA outcomes as the standard benchmark. RESULTS In the context of DR diagnosis and staging, the kappa coefficients for NMFP-assisted telemedicine and FFA were recorded at 0.775 and 0.689 respectively, indicating substantial intermethod agreement. Moreover, the NMFP-assisted telemedicine's predictive accuracy for positive FFA outcomes, as denoted by the area under the ROC curve, was remarkably high at 0.955, within a confidence interval of 0.914 to 0.995 and a statistically significant P-value of less than 0.001. This predictive model exhibited a specificity of 100%, a sensitivity of 90.9%, and a Youden index of 0.909. CONCLUSION NMFP-assisted telemedicine represents a pragmatic, objective, and precise modality for fundus examination, particularly applicable in the context of endocrinology inpatient care and primary healthcare settings for diabetic patients. Its implementation in these scenarios is of paramount significance, enhancing the clinical accuracy in the diagnosis and therapeutic management of DR. This methodology not only streamlines patient evaluation but also contributes substantially to the optimization of clinical outcomes in DR management.

MEDICAL HYPOTHESIS, DISCOVERY & INNOVATION OPHTHALMOLOGY JOURNAL 2023; 11:162-170. [PMID: 37641607 PMCID: PMC10460246 DOI: 10.51329/mehdiophthal1460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Accepted: 01/04/2023] [Indexed: 08/31/2023]
Abstract
Background Screening for diabetic retinopathy in the community without compromising the routine work of ophthalmologists at hospitals is the essence of teleophthalmology. This study was aimed at investigating the efficacy of teleophthalmology practice for screening diabetic retinopathy from 2012 to 2020. It was also aimed at comparing the 2-year prevalence of camps organized by a district hospital in South India, as well as the footfall, reporting, follow-up, patient response, and diagnostic efficacy at these camps. Methods All patients with diabetes and unexplained vision deterioration attending the mobile camp units underwent non-dilated fundus photography. Patients underwent teleconsultation with the ophthalmologist at the district hospital, and those requiring intervention were called to the district hospital. Trends were studied for the number of patients reporting to the hospital. Patient satisfaction was recorded based on a questionnaire. Results A total of 682 camps were held over 8 years, and 30 230 patients were examined. Teleconsultation was done for 12 157 (40.21%) patients. Patients requiring further investigations, intervention for diabetic retinopathy, or further management of other ocular pathologies were urgently referred to the district hospital (n= 3293 [10.89%] of 30 230 examined patients). The severity and presence of clinically significant macular edema increased significantly with an increased duration of diabetes mellitus (P < 0.001). The percentage of teleconsultations showed an increasing trend over the years (P = 0.001). Similarly, considering trends of patients reporting to the hospital, the attrition rate decreased over the years (P < 0.05). A total of 10 974 of 12 157 (90.27%) patients who underwent teleophthalmic consultation were satisfied with the service. Conclusions Teleconsultations over the years showed an increasing trend, and the attrition rate decreased over the years. Teleophthalmology is achieving success in providing high-quality service, easy access to care, and in increasing patient satisfaction. Future studies on the role of teleophthalmology for other leading preventable causes of blindness seem possible and necessary.

Abstract
Teleophthalmology is the provision of ophthalmic care using digital medical equipment and telecommunications technology. While teleophthalmology has been practiced since the 1990s, it became a crucial medical service during the COVID-19 pandemic when doctors were required to make diagnoses from a distance. This was certainly the case in Saudi Arabia, a relatively large country with limited medical workforce to meet demands, yet a high prevalence of diseases such as diabetes, glaucoma, and cataracts which are considered leading causes of visual impairment. In response to the pandemic, Saudi Arabia's Ministry of Health issued scientific instruction manuals and guidelines for health-care providers which paved the way for increased use of digital technologies and solutions to mitigate the health and economic impacts of COVID-19. The pandemic served to accelerate the use of virtual ophthalmology in Saudi Arabia with the most common teleophthalmology applications being teleconsultation and disease-specific applications such as diabetic retinopathy and retinopathy of prematurity. Although some challenges relating to implementing teleophthalmology in Saudi Arabia remain, it is felt that there are great opportunities to expand the use of telemedicine in ophthalmology in this country.

Ophthalmol Ther 2021; 10:445-464. [PMID: 34156632 PMCID: PMC8217784 DOI: 10.1007/s40123-021-00353-2] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Accepted: 05/15/2021] [Indexed: 01/30/2023] Open
Abstract
In the presence of the ever-increasing incidence of diabetes mellitus (DM), the prevalence of diabetic eye disease (DED) is also growing. Despite many improvements in diabetic care, DM remains a leading cause of visual impairment in working-age patients. So far, prevention has been the best way to protect vision. The sooner we diagnose DED, the more effective the treatment is. Thus, diabetic retinopathy (DR) screening, especially with imaging techniques, is a method of choice for vision protection. To alleviate the burden of diabetic patients who need ophthalmic care, telemedicine and in-home testing are used, supported by artificial intelligence (AI) algorithms. This is why we decided to evaluate current image teleophthalmology methods used for DR screening. We searched the PubMed platform for papers published over the last 5 years (2015–2020) using the following key words: telemedicine in diabetic retinopathy screening, diabetic retinopathy screening, automated diabetic retinopathy screening, artificial intelligence in diabetic retinopathy screening, smartphone diabetic retinopathy testing. We have included 118 original articles meeting the above criteria, discussing imaging diabetic retinopathy screening methods. We have found that fundus cameras, stable or mobile, are most commonly used for retinal photography, with portable fundus cameras also relatively common. Other possibilities involve the use of ultra-wide-field (UWF) imaging and even optical coherence tomography (OCT) devices for DR screening. Also, the role of smartphones is increasingly recognized in the field. Retinal fundus images are assessed by humans instantly or remotely, while AI algorithms seem to be useful tools facilitating retinal image assessment. The common use of smartphones and availability of relatively cheap, easy-to-use adapters for retinal photographs augmented by AI algorithms make it possible for eye fundus photographs to be taken by non-specialists and in non-medical setting. This opens the way for in-home testing conducted on a much larger scale in the future. In conclusion, based on current DR screening techniques, we can suggest that the future practice of eye care specialists will be widely supported by AI algorithms, and this way will be more effective.

Abstract
ABSTRACT
Introduction: Teleophthalmology may assist the healthcare sector in adapting to limitations imposed on
clinical practice by a viral pandemic. A scoping review is performed in this study to assess the current
applications of teleophthalmology for its suitability to diagnose, monitor or manage ophthalmological
conditions with accuracy.
Methods: A search of PubMed was conducted for teleophthalmology-related articles published from
1 January 2018 to 4 May 2020. Only articles that focused on the use of teleophthalmology in terms of
diagnosis and management, as well as its benefits and detriments, were included. The Mixed Methods
Appraisal Tool (MMAT) was used to assess the quality of the included articles.
Results: A total of 38 articles were assessed at the full-text level. There were 2 qualitative studies and
1 quantitative randomised controlled trial, while the majority were either quantitative descriptive studies
(19, 50.0%) or quantitative non-randomised studies (16, 42.1%). Overall, 8 studies described reducing
manpower requirements, 4 described reducing direct patient–doctor contact, 17 described storage of
medical imaging and clinical data, and 9 described real-time teleconferencing. The MMAT analysis
revealed limitations in appropriate sampling strategy in both quantitative non-randomised studies (9 of
16, 56.3%) and quantitative descriptive studies (9 of 19, 47.4%). Cost-effectiveness of teleophthalmology
was not performed in any included study.
Conclusion: This current review of the various aspects of teleophthalmology describes how it may
potentially assist the healthcare sector to cope with the limitations imposed by a viral pandemic through
technology. Further research is required to evaluate the cost-effectiveness of the various strategies.

Abstract
Background: Although many publications in diabetic retinopathy (DR) have been reported, there is no bibliometric analysis. Purpose: To perform a bibliometric analysis in the field of diabetic retinopathy (DR) research, to characterize the current international status of DR research, to identify the most effective factors involved in this field, and to explore research hotspots in DR research. Methods: Based on the Web of Science Core Collection (WoSCC), a bibliometric analysis was conducted to investigate the publication trends in research related to DR. Knowledge maps were constructed by VOSviewer v.1.6.10 to visualize the publications, the distribution of countries, international collaborations, author productivity, source journals, cited references and keywords, and research hotspots in this field. Results: In total, 11,839 peer-reviewed papers were retrieved on DR from 2010 to 2019, and the annual research output increased with time. The United States ranks highest among countries with the most publications. The most active institution is the University of Melbourne. Wong, TY contributed the largest number of publications in this field. Investigative Ophthalmology & Visual Science was the most prolific journal in DR research. The top-cited references mainly investigated the use of anti-vascular endothelial growth factor (VEGF) medications in the management of DR, and the keywords formed 6 clusters: Discussion: With the improvement of living standard, DR has gradually become one of the important causes of blindness, and has become a hot spot of public health research in many countries. The application of deep learning and artificial intelligence in diabetes screening and anti-VEGF medications in the management of DR have been the research hotspots in recent 10 years. Conclusions: Based on data extracted from the WoSCC, this study provides a broad view of the current status and trends in DR research and may provide clinicians and researchers with insight into DR research and valuable information to identify potential collaborators and partner institutions and better predict their dynamic directions.

Abstract
Purpose Technological advances in recent years have resulted in the development and implementation of various modalities and techniques enabling medical professionals to remotely diagnose and treat numerous medical conditions in diverse medical fields, including ophthalmology. Patients who require prolonged isolation until recovery, such as those who suffer from COVID-19, present multiple therapeutic dilemmas to their caregivers. Therefore, utilizing remote care in the daily workflow would be a valuable tool for the diagnosis and treatment of acute and chronic ocular conditions in this challenging clinical setting. Our aim is to review the latest technological and methodical advances in teleophthalmology and highlight their implementation in screening and managing various ocular conditions. We present them as well as potential diagnostic and treatment applications in view of the recent SARS-CoV-2 virus outbreak. Methods A computerized search from January 2017 up to March 2020 of the online electronic database PubMed was performed, using the following search strings: “telemedicine,” “telehealth,” and “ophthalmology.” More generalized complementary contemporary research data regarding the COVID-19 pandemic was also obtained from the PubMed database. Results A total of 312 records, including COVID-19-focused studies, were initially identified. After exclusion of non-relevant, non-English, and duplicate studies, a total of 138 records were found eligible. Ninety records were included in the final qualitative analysis. Conclusion Teleophthalmology is an effective screening and management tool for a range of adult and pediatric acute and chronic ocular conditions. It is mostly utilized in screening of retinal conditions such as retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration; in diagnosing anterior segment condition; and in managing glaucoma. With improvements in image processing, and better integration of the patient’s medical record, teleophthalmology should become a more accepted modality, all the more so in circumstances where social distancing is inflicted upon us. ![]()

Abstract
PURPOSE To define and develop a model of excellence for the clinical management of diabetic macular edema (DME) patients in a real-world setting. METHODS A multidisciplinary joint commission (5 ophthalmologists, 1 nurse, and 1 pharmaceutic) established a series of preliminary recommendations based on clinical guidelines and DME activity results from 8 Pilot Hospitals (PH). These were validated by members of each PH and a group of DME patients in discussion workshops. Thus, the validated guideline (VG) took into consideration different aspects, namely, main core points (ranging 0-100), criteria, and indicators. Finally, each PH own setting was compared to the VG in order to settle down a starting point to clinical excellence. RESULTS Mean PH score was 51.5 (range 30-65). As compared to their maximum, main points that showed best scores were Clinical Guidelines and Protocols (78%) and Portfolio of Services (73%). Topics reaching close to 50% scoring included Resources (55%), Innovation (54%), Care Process (53%), Organization (52%), and Leadership (50%). Lowest scores were observed in the Strategic Alliances (46%) and Staff (37%) points. CONCLUSIONS Analysis of each PH by the VG delivered a global vision of the starting situation, especially focused in the identification of the different improvement areas. In order to further extend this model into the Public Health System, the effect of implementing it in different hospitals should be assessed to analyze its impact on daily clinical practice and health economics.
