RESUMEN

PURPOSE: This study assesses the diagnostic efficacy of offline Medios Artificial Intelligence (AI) glaucoma software in a primary eyecare setting, using non-mydriatic fundus images from Remidio's Fundus-on-Phone (FOP NM-10). AI results were compared with tele-ophthalmologists' diagnoses and with a glaucoma specialist's assessment for those participants referred to tertiary eyecare hospital. DESIGN: Prospective, cross-sectional study PARTICIPANTS: 303 participants from 6 satellite vision centers of a tertiary eye hospital METHODS: At the vision center, participants underwent comprehensive eye evaluations, including clinical history, visual acuity measurement, slit lamp examination, intraocular pressure measurement, and fundus photography using the FOP NM-10 camera. Medios AI-Glaucoma software analysed 42-degrees disc-centric fundus images, categorizing them as normal, glaucoma, or suspect. Tele-ophthalmologists who were glaucoma fellows with a minimum of 3 years of ophthalmology and 1 year of glaucoma fellowship training, masked to AI results, remotely diagnosed subjects based on the history and disc appearance. All participants labelled as disc suspects or glaucoma by AI or tele-ophthalmologists underwent further comprehensive glaucoma evaluation at the base hospital, including clinical examination, Humphrey visual field analysis (HFA), and Optical Coherence Tomography (OCT). AI and tele-ophthalmologist diagnoses were then compared with a glaucoma specialist's diagnosis. MAIN OUTCOME MEASURES: Sensitivity and Specificity of Medios AI RESULTS: Out of 303 participants, 299 with at least one eye of sufficient image quality were included in the study. The remaining 4 participants did not have sufficient image quality in both eyes. Medios AI identified 39 participants (13%) with referable glaucoma. The AI exhibited a sensitivity of 0.91 (95% CI: 0.71 - 0.99) and specificity of 0.93 (95% CI: 0.89 - 0.96) in detecting referable glaucoma (definite perimetric glaucoma) when compared to tele-ophthalmologist. The agreement between AI and the glaucoma specialist was 80.3%, surpassing the 55.3.% agreement between the tele-ophthalmologist and the glaucoma specialist amongst those participants who were referred to the base hospital. Both AI and the tele-ophthalmologist relied on fundus photos for diagnoses, while the glaucoma specialist's assessments at the base hospital were aided by additional tools such as HFA and OCT. Furthermore, AI had fewer false positive referrals (2 out of 10) compared to the tele-ophthalmologist (9 out of 10). CONCLUSION: Medios offline AI exhibited promising sensitivity and specificity in detecting referable glaucoma from remote vision centers in southern India when compared with teleophthalmologists. It also demonstrated better agreement with glaucoma specialist's diagnosis for referable glaucoma participants.

RESUMEN

The utilization of non-mydriatic fundus photography-assisted telemedicine to screen patients with diabetes mellitus for diabetic retinopathy provides an accurate, efficient, and cost-effective method to improve early detection of disease. It has also been shown to correlate with increased participation of patients in other aspects of diabetes care. In particular, patients who undergo teleretinal imaging are more likely to meet Comprehensive Diabetes Care Healthcare Effectiveness Data and Information Set metrics, which are linked to preservation of quality-adjusted life years and additional downstream healthcare savings.

RESUMEN

Purpose: The aim of the research was to evaluate the use of teleophthalmology at a university practice during the COVID-19 pandemic, specifically examining precision, effectiveness, and patient satisfaction. Patients and Methods: Telemedicine visits were offered to new and established patients requesting appointments with the Stony Brook University Department of Ophthalmology between March 30 and June 2, 2020. Records from these visits were reviewed for chief complaint, past medical and ocular history, diagnoses, treatment/management, and providers' sub-specialty. Precision was determined by comparing agreement between diagnoses of the telemedicine visit with those of the subsequent in-person visit. The decision to follow up in person was made by the physician and patient. Diagnostic precision as well as progression, improvement, or stability of patients' symptoms were determined by the physician's assessment at follow-up visits. Post-telemedicine visit satisfaction surveys were sent to all patients. Results: Telemedicine visits were offered to 783 patients, 520 (66.4%) of whom accepted. Of these 520 patients, 409 (78.7%) were established and 105 (20.2%) had in-person, follow-up visits. Overall, the diagnostic precision of the follow-up visits was 89.5%. Precision differed significantly across ophthalmologic subspecialties. Of the patients who had in-person follow-up visits, 56.8% remained stable, 32.4% improved, and 10.8% worsened. Established patients presented with more extensive ocular histories/procedures and experienced a higher percentage of worsening symptoms/disease stage compared to new patients. Oculoplastics/orbit was the most prevalent diagnostic subspecialty that worsened. Surveys were sent to all patients completing telemedicine visits, 15.0% of whom responded. Overall satisfaction was 91.9%, although only 23.0% of respondents preferred telemedicine to an in-office visit. Conclusion: Telehealth provides high levels of precision and patient satisfaction for a wide range of ophthalmologic visits, although most patients still prefer in-office examinations. Employing teleophthalmology for follow-up and emergency care may provide patients with an effective alternative during pandemic situations and beyond.

Telemedicine involves integration of modern telecommunications technology into medical practice. Over the years, it has demonstrated greater and more widespread utility for different medical specialties, including ophthalmology. As a response to the recent COVID-19 pandemic, the Stony Brook University Department of Ophthalmology provided an option of telemedicine for patients in lieu of in-person eye examinations. In this paper, Stony Brook ophthalmologists report on their experience with teleophthalmology, particularly regarding its utilization, accuracy, effectiveness, precision, and acceptability. The authors examined the records of 520 patients who had telemedicine encounters between March 30 and June 2, 2020. Precision was determined by comparing the initial and final diagnoses of all patients who had an in-person follow-up appointment following a telemedicine visit. Of 105 patients that followed up, precision was determined to be 89.5%. Precision was compared across ophthalmologic subspecialties and found to be statistically similar (p>0.05). Approximately a third of patients improved, while nearly 11% worsened. Established and oculoplastics patients were more significantly likely to worsen. Surverys were sent out to study patients to gauge their satisfaction with their telemedicine experience. Although satisfaction was nearly 92%, only 23% of patients preferred telemedicine to an in-person physician encounter. The authors conclude that teleophthalmology provides a high level of diagnostic precision and patient satisfaction; nevertheless, most patients prefer in-person physician encounters. Telemedicine may provide an effective alternative to in-person ophthalmology assessments, especially during a pandemic. There appears to be a lesser but potentially useful role for teleophthalmology in a non-pandemic setting.

RESUMEN

Purpose: To investigate the robustness and variability of a novel kinetic visual field (VF) screening method termed rapid campimetry (RC). Methods: In RC visual field (VF) screening is enabled via kinetic-based testing on any computer (10°/4.7 s at 40-cm viewing distance) and high contrast in a dark room (1 cd/cm2). In experiment (1): 30 participants [20 healthy participants (HC), 5 glaucoma patients (GLA) and 5 patients with cataract (CAT)] were included to test the intra-session variability (fatigue effect) and the following effects on RC: room illumination (140 cd/m2), ±3 D refractive errors, media opacity. In experiment (2): Inter-session variability (1-3 weeks apart) was assessed in 10 HC and 10 GLA. Since RC detects absolute scotomas, the outcome measure was the size of physiological (blindspot) and pathological (glaucoma) scotomas in degrees. A repeated measures ANOVA was employed in experiment 1 and intraclass correlation (ICC) in experiment 2. Results: Neither the size of the blindspot nor the VF defects differed significantly between the different testing conditions. For intra-session variability, the average bias of blindspot size was -0.6 ± 2.5°, limits of agreement (LOA), in comparison to 0.3 ± 1.5° for VF defects, both with ICC of 0.86 and 0.93, respectively. For the inter-session repeatability, the average bias and LOA for blindspot size was 0.2 ± 3.85° in comparison 1.6 ± 3.1° for VF defects, both with ICC of 0.87 and 0.91, respectively. Conclusion: RC was robust to suboptimal testing VF conditions and showed good-to-excellent reliability between VF testing visits holding high potential for teleophthalmology.

RESUMEN

INTRODUCTION: This study reports our experiences with systematic retinal screening in Denmark through optometrists with access to tele-ophthalmological services before, during, and after the COVID-19 pandemic. METHODS: We evaluated an optometrist-based retinal screening system with a referral option for tele-ophthalmological service by a consultant ophthalmologist within the time period of August 1, 2018 to September 30, 2023. The optometrist collected patient history, refraction, best-corrected visual acuity, intraocular pressure, basic slit-lamp examination, 4-in-1 visual field report, and retinal imaging using color fundus 45° photography. Tele-ophthalmological services were provided by consultant ophthalmologists. Within pre-defined periods of pre-COVID-19, COVID-19, and post-COVID-19, we evaluated the rate of referrals to the tele-ophthalmological service, diagnoses made, and referrals to the public healthcare system. RESULTS: A total of 1,142,028 unique individuals, which corresponded to 19.1% of the entire population of Denmark, underwent screening by the optometrists; 50,612 (4.4%) of these individuals were referred to the tele-ophthalmological examination by consultant ophthalmologists. A referral for further ophthalmic examination, either at hospital or at an ophthalmic practice, was made for 10,300 individuals (20.4% of those referred for tele-ophthalmology, corresponding to 0.9% of the population screened). The referral rate from the screening to the tele-ophthalmological service increased from before COVID-19 (3.4%) to during COVID-19 (4.3%) and further after COVID-19 (6.4%). This increase coincided with an increasing prevalence of conditions seen in the tele-ophthalmological service. CONCLUSION: During a period of 5 years, 19.1% of the entire population of Denmark underwent retinal screening. This provided an adjunctive health service during a period of severe strain on the public healthcare system, while limiting the number of excessive referrals to the public healthcare system. Temporal trends illustrated an increased pattern of use of a large-scale tele-ophthalmological system.

RESUMEN

INTRODUCTION: Digital exclusion is a growing challenge when deploying digital patient care pathways and a potential barrier to widespread implementation, especially in the field of smartphone-based self-monitoring of vision. This retrospective case series seeks to examine the characteristics of individuals who adhere to a smartphone home monitoring programme using the Alleye app for retinal disease, with a focus on digital exclusion, social deprivation and clinical outcomes. METHODS: We conducted a retrospective analysis of 89 patients with retinal pathologies including diabetic retinopathy and retinal vein occlusions at Moorfields Eye Hospital participating in an Alleye home monitoring programme between April 2020 and November 2022. Postcodes were used to determine the Digital Exclusion Risk Index (DERI) and the Index of Multiple Deprivation (IMD) rebased for London. Clinical information from the electronic patient record and Alleye app usage data were extracted for each patient. Associations between the DERI/IMD, clinical parameters and app use were examined using multivariable regression models. RESULTS: Mean DERI was 2.56 (standard deviation [SD] = 0.36), IMD was 6.25 (SD = 2.79), visual acuity (VA) in the better eye at study entry was 83.28 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (SD = 7.92), and mean follow-up was 344.46 days (SD = 260.13). During the observation period, 36% received an intravitreal injection (IVI) and VA fell by at least ten letters in approximately one in four patients. In 87.5% of patients requiring IVI, the use of the app increased. We found no association between clinical parameters and programme adherence for DERI or IMD. CONCLUSIONS: We found no association between high digital exclusion risk and high social deprivation with monitoring adherence to smartphone-based self-monitoring of vision, contrary to the currently available evidence. This suggests that smartphone-based self-monitoring of vision is accessible to population groups of varying digital exclusion and social deprivation risk, and can be safely employed to monitor clinical progression.

RESUMEN

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic has caused significant transformations in healthcare. Many countries began the rapid development and adoption of telemedicine to avoid the spread of the pandemic and created an innovative model for healthcare delivery. This study identified the critical antecedents that affected the considered healthcare outcomes via teleophthalmology in Eastern Taiwan during the COVID-19 pandemic. METHODS: This study's participants included residents of five towns in Taitung County who had experience with teleophthalmology. This study analyzed the structured questionnaires completed by the participants to validate the proposed research framework. Statistical methods were used to verify the research models, including descriptive statistical analysis, confirmatory factor analysis, and structural equation modeling. The date of this study was from 1 October 2020 to 31 July 2023. RESULTS: The results of this study reveal that the average monthly use of teleophthalmology by individuals in rural areas increased annually. Females tended to utilize teleophthalmology services more than males. There were no significant differences across any of the constructs with respect to age or educational level. Additionally, the patients' awareness of healthcare accessibility via and the communication quality of teleophthalmology simultaneously affected teleophthalmology's adoption and service quality, which in turn jointly affected health outcomes. Both healthcare accessibility and communication quality were the antecedents of the healthcare outcomes. The health outcomes refer to the impact of teleophthalmology on the quality of the patients' health and well-being. Additionally, teleophthalmology's adoption and service quality acted as mediators. CONCLUSIONS: This study's findings are expected to increase attention to the healthcare outcomes and antecedents of teleophthalmology to promote better telemedicine practices and services for rural residents.

This comprehensive review examines the current applications of AI in ophthalmology, highlighting its significant contributions to diagnostic accuracy, treatment efficacy, and patient care. AI technologies, such as deep learning algorithms, have demonstrated exceptional performance in the early detection and diagnosis of various eye conditions, including diabetic retinopathy (DR), age-related macular degeneration (AMD), and glaucoma. Additionally, AI has enhanced the analysis of ophthalmic imaging techniques like optical coherence tomography (OCT) and fundus photography, facilitating more precise disease monitoring and management. The review also explores AI's role in surgical assistance, predictive analytics, and personalized treatment plans, showcasing its potential to revolutionize clinical practice and improve patient outcomes. Despite these advancements, challenges such as data privacy, regulatory hurdles, and ethical considerations remain. The review underscores the need for continued research and collaboration among clinicians, researchers, technology developers, and policymakers to address these challenges and fully harness the potential of AI in improving eye health worldwide. By integrating AI with teleophthalmology and developing AI-driven wearable devices, the future of ophthalmic care promises enhanced accessibility, efficiency, and efficacy, ultimately reducing the global burden of visual impairment and blindness.

RESUMEN

This study assesses the quality of retinal images captured using a non-mydriatic fundus camera within a teleophthalmologic platform in Taiwan. The objective was to evaluate the effectiveness of non-mydriatic fundus cameras for remote retinal screening and identify factors impacting image quality. From June 2020 to August 2022, 629 patients from five rural infirmaries underwent ophthalmic examinations, with fundus images captured without pupil dilation. These images were reviewed by senior ophthalmologists and graded based on quality. The results indicated that approximately 70% of images were of satisfactory diagnostic quality. Risk factors for poor image quality included older age, the presence of cataracts, pseudophakia, and diabetes mellitus. This study demonstrates the feasibility of using non-mydriatic fundus cameras for teleophthalmology, highlighting the importance of identifying and addressing factors that affect image quality to enhance diagnostic accuracy in remote settings.

RESUMEN

Background: This systematic review of teleophthalmology services in Australia, the United States of America (USA), Canada, and the United Kingdom (UK) during the COVID-19 pandemic is aimed to evaluate changes in teleophthalmology, comparing them to New Zealand (NZ). Methods: A literature search of electronic databases Scopus, Proquest, PubMed, Embase, Web of Science, Cochrane Library, Google Scholar, and Google was conducted using search terms: telemedicine, ophthalmology, teleophthalmology/teleophthalmology, and COVID/COVID-19/coronavirus/covid-pandemic. Studies describing teleophthalmology services created in response to COVID-19 restrictions from March 1, 2020, to January 31, 2024, were analyzed. Results: Of the articles, 37 describing 29 discrete teleophthalmology services were included. There were 15 services in the USA, seven in the UK, two in Canada, two in Australia, and three in NZ. The models of care in the USA were well described, and teleophthalmology was used for general, external, anterior segment, neuro-ophthalmology, and oculoplastic consults, as well as for grading of fundus images in the emergency department setting. In the UK, teleophthalmology was used for general eye care, oculoplastics, and pediatric ophthalmology. In Australia, teleophthalmology was used for postglaucoma surgery monitoring of Intraocular Pressure. In NZ, teleophthalmology was used for general eye consults and triaging, but no formal models were described. Conclusion: COVID-19 offered a unique opportunity for re-examination and expansion of teleophthalmology services globally. Video-based and home-screening teleophthalmology services are feasible but have limitations. Investing in multidisciplinary and community-based technology partnerships can create more equitable teleophthalmology care models (to complement and, when necessary, replace traditional in-person consults), within existing frameworks, making eye care more accessible and efficient.

RESUMEN

Background: The availability and utilization of telehealth services have been rapidly increasing in the past decade, which paved the way for ophthalmological care to be offered more easily and conveniently. However, the proficiency of telehealth in the context of ophthalmical care still requires further studies to prove its effectiveness. This study examined the proficiency of general practitioners in a telemedicine platform in identifying red flag symptoms, suggestive of retinal detachment, and devising optimal management strategies. Methods: Our cross-sectional study used chat-based consultations on Altibbi Telemedicine platform (2018-2023) to study ophthalmical patients presenting with "blurred vision" or "blindness." Those endorsing red flag symptoms were categorized as having "positive symptomatology" and those reporting none as having "negative symptomatology." Management plans were classified as referral or reassuring. Statistical analysis was performed using IBM's Statistical Package for Social Sciences to examine associations between symptomatology and other variables. p values below 0.05 were considered statistically significant. Results: Five hundred and fifty (n = 550) patients with a mean age 22.5 ± 13 years were included. Patients expressing positive symptomatology were more likely to be referred relative to those expressing negative symptomatology (81% vs. 61%, p < 0.001). No significant difference was found between genders and referral (p = 0.053) or age and referral (p = 0.231). Multivariate regression showed a significant correlation between positive symptoms and referral (adjusted odds ratio [aOR]: 2.0; 95% confidence interval [95% CI]: 1.3-3.3), none between gender (aOR: 1.5; 95% CI: 0.9-2.2) or age (aOR: 1.0; 95% CI: 0.9-1.1) and referral odds. Conclusion: The telemedicine platform studied is effective in referring cases with red flag symptoms to urgent care, regardless of age and gender.

RESUMEN

Objective: To determine if dermoscopy, a technique widely utilized in dermatology for improved diagnosis of skin lesions, can be used comfortably for evaluating periorbital, eyelid, and conjunctival lesions. Design: Proof-of-concept study in which a technique for performing dermoscopy near the eye was developed, related educational material was prepared, and a protocol for dermoscopic image capture was created. Methods: Technicians used the developed materials to learn to take high-quality pictures with a 10x dermoscope attached to a standard cell phone camera. The images were assessed for diagnostic utility by an oculoplastic surgeon and two dermatologists. Participants: 115 patients recruited from ophthalmology clinics from July 2021 to April 2023 were photographed, yielding 129 lesions with high-quality dermoscopic images as assessed by an oculoplastic surgeon and two dermatologists. Results: Technicians reported a significant increase in confidence (measured on a 1-10 scale) with dermoscopy after training (pre-instruction mean = 1.72, median = 1, mode = 1, IQR = 1.25 vs mean = 7.69, median = 7.75, mode = 7 and 8, IQR = 1.5 post-instruction. Wilcoxon rank sum test with continuity correction, W = 0, p < 0.001, paired t = 13.95, p < 0.0001). Incorporating a contact plate with a 4 × 4mm reticule on the dermoscope aided in photographing ocular and periocular lesions. Conclusion: Medical support staff in eye-care offices can be taught to use dermoscopes to capture high-quality images of periorbital, eyelid, and conjunctival lesions. Dermoscopy illuminates diagnostic features of lesions and thus offers a new avenue to improve decision-making in ophthalmology. Dermoscopy can be incorporated into telemedicine evaluations by ophthalmologists, oculoplastic surgeons, or affiliated dermatologists for triage of or rendering advice to patients and for planning of surgery if needed.

RESUMEN

Fundamentos: La diabetes mellitus es una enfermedad crónica con alta morbimortalidad que afecta a 537 millones de adultos en el mundo. España es el segundo país europeo en prevalencia, con un 14,8% en población de veinte-setenta y nueve años, con 11,6 casos por cada 1.000 personas/año. La retinopatía diabética (RD) es la quinta causa de pérdida de visión a nivel mundial y la séptima causa de ceguera/discapacidad visual entre afiliados a la Organización Nacional de Ciegos de España (ONCE). La detección precoz de RD previene la ceguera en diabéticos y está condicionada por la hemoglobina glicosilada. El objetivo de este trabajo fue analizar el manejo de los pacientes diabéticos en la comarca del Aljarafe (Sevilla) e identificar oportunidades de mejora en la coordinación de su seguimiento entre el médico de Atención Primaria y el médico oftalmólogo. Métodos: Se realizó un estudio observacional retrospectivo (2016-2019) con los pacientes registrados en el censo de diabéticos de los veintiocho municipios del Aljarafe. Se consultó la historia de salud de Atención Primaria y Hospital, así como el programa de Telemedicina. En cuanto al análisis estadístico, para variables cualitativas se calcularon totales y porcentajes; para variables cuantitativas, media y distribución estándar (si distribución normal), y la mediana y cuartiles (distribución no normal).

Background: Diabetes mellitus is a chronic disease with high morbidity and mortality, affecting 537 million adults worldwide. Spain is the second European country in prevalence, with 14.8% in the population aged twenty/seventy-nine years; with 11.6 cases per 1,000 people/year. Diabetic retinopathy (DR) is the fifth cause of vision loss worldwide and the seventh cause of blindness/visual impairment among members of the National Organization of the Blind in Spain (ONCE). Early detection of DR prevents blindness in diabetics and is conditioned by glycosylated hemoglobin. The aim of this paper was to analyze the management of diabetic patients in Aljarafe region (Seville) and identify opportunities for improvement in the coordination of their follow-up between the Primary Care physician and the ophthalmologist. Methods: A retrospective observational study (2016-2019) was carried out, with patients registered in the diabetic census of the twenty-eight municipalities of Aljarafe. The primary care and hospital health history, and telemedicine program were consulted. About statistical analysis, for qualitative variables, totals and percentages were calculated; for quantitative variables, mean and standard devia-tion (if normally distributed) and median and quartiles (if non-normally distributed).

CONCLUSIONS: Most patients have adequate screening, and more than half have determinations within range. However, a significant percentage with no glycated hemoglobin within range lack fundoscopic control, and another smaller group lack fundoscopic or metabolic control, with inter-municipal variability. We propose to improve communication channels between levels.

RESUMEN

PURPOSE: This American Academy of Ophthalmology Ophthalmic Technology Assessment aims to assess the effectiveness of conventional teleretinal screening (TS) in detecting diabetic retinopathy (DR) and diabetic macular edema (DME). METHODS: A literature search of the PubMed database was conducted most recently in July 2023 to identify data published between 2006 and 2023 on any of the following elements related to TS effectiveness: (1) the accuracy of TS in detecting DR or DME compared with traditional ophthalmic screening with dilated fundus examination or 7-standard field Early Treatment Diabetic Retinopathy Study photography, (2) the impact of TS on DR screening compliance rates or other patient behaviors, and (3) cost-effectiveness and patient satisfaction of TS compared with traditional DR screening. Identified studies then were rated based on the Oxford Centre for Evidence-Based Medicine grading system. RESULTS: Eight level I studies, 14 level II studies, and 2 level III studies were identified in total. Although cross-study comparison is challenging because of differences in reference standards and grading methods, TS demonstrated acceptable sensitivity and good specificity in detecting DR; moderate to good agreement between TS and reference-standard DR grading was observed. Performance of TS was not as robust in detecting DME, although the number of studies evaluating DME specifically was limited. Two level I studies, 5 level II studies, and 1 level III study supported that TS had a positive impact on overall DR screening compliance, even increasing it by more than 2-fold in one study. Studies assessing cost-effectiveness and patient satisfaction were not graded formally, but they generally showed that TS was cost-effective and preferred by patients over traditional surveillance. CONCLUSIONS: Conventional TS is an effective approach to DR screening not only for its accuracy in detecting referable-level disease, but also for improving screening compliance in a cost-effective manner that may be preferred by patients. Further research is needed to elucidate the ideal approach of TS that may involve integration of artificial intelligence or other imaging technologies in the future.

RESUMEN

During and after the COVID-19 pandemic, teleophthalmology provided access to eye care for rural populations. This study aimed to assess the efficacy of and satisfaction with an integrated real-time videoconferencing module. This project incorporated ophthalmic instruments and telecommunication devices and provided on-site consultations via videoconferencing. Both patients and healthcare providers completed satisfaction questionnaires. From May 2020 to May 2021, this project provided eye care services to 395 patients (aged 6-90 years). The most frequent eye condition was chronic conjunctivitis (n = 197), followed by senile cataract (n = 163), dry eye (n = 103), and refractive error (n = 95). Among them, 40 (10.1%) patients were referred to secondary or tertiary hospitals for further evaluation or treatment. In total, 181 recruited respondents provided good satisfaction scores in all dimensions, including quality of medical care (4.50 of 5.00), financial aspects of care (4.48), supportive attitude toward the project (4.47), quality of service (4.40), and quality of telecommunication (4.40). Women had a substantially more supportive attitude toward the project, and 25 healthcare providers provided low ratings in areas representing the quality of telecommunication (4.04) and user-friendliness of the instrument (4.00). This teleophthalmology system provided efficient and satisfactory eye care to participants in remote communities. However, better internet access and training in instrument use can reduce obstacles to the future implementation of the project.

RESUMEN

Glaucoma is one of the leading causes of irreversible blindness in the world. Early diagnosis and treatment increase the chances of preserving vision. However, despite advances in techniques for the functional and structural assessment of the retina, specialists still encounter many challenges, in part due to the different presentations of the standard optic nerve head (ONH) in the population, the lack of explicit references that define the limits of glaucomatous optic neuropathy (GON), specialist experience, and the quality of patients' responses to some ancillary exams. Computer vision uses deep learning (DL) methodologies, successfully applied to assist in the diagnosis and progression of GON, with the potential to provide objective references for classification, avoiding possible biases in experts' decisions. To this end, studies have used color fundus photographs (CFPs), functional exams such as visual field (VF), and structural exams such as optical coherence tomography (OCT). However, it is still necessary to know the minimum limits of detection of GON characteristics performed through these methodologies. This study analyzes the use of deep learning (DL) methodologies in the various stages of glaucoma screening compared to the clinic to reduce the costs of GON assessment and the work carried out by specialists, to improve the speed of diagnosis, and to homogenize opinions. It concludes that the DL methodologies used in automated glaucoma screening can bring more robust results closer to reality.

RESUMEN

Purpose: Timely diagnosis of diabetic retinopathy is important in preventing vision loss. This study aims to determine if remote retinal imaging enables earlier eye care access among newly-diagnosed diabetic patients. Design: Retrospective cohort study. Methods: Using the OptumLabs® Data Warehouse - a longitudinal, real-world dataset containing deidentified administrative claims and electronic health record (EHR) data, we included 968 846 adults with newly diagnosed type 2 diabetes and at least 1 year of continuous enrollment. We compared time from initial diabetes diagnosis to first eye exam by remote screening or in-person eye exam. Results: We found that at year 1 after diagnosis, 5459 (0.56%) patients underwent remote imaging and 208 023 (21.5%) underwent in-person exam. The mean (95% CI) time to eye exam was 3.48 (3.38-3.58) months for remote imaging and 4.22 (4.20-4.23) months for in-person visits (p < 0.0001). Interestingly, 27.5% of remote screenings were performed on the same day of diabetes diagnosis. Excluding same-day encounters, mean time to eye exam was 4.80 (4.68-4.91) months for remote imaging and 4.85 (4.83-4.86) months for in-person eyecare (p = 0.4). Conclusions: Thus, teleophthalmology may enable earlier eye care access among patients with newly-diagnosed diabetes, primarily with same-day screenings. Increased adoption of teleretinal screening may enable earlier detection of diabetic retinopathy and prevent vision loss.

RESUMEN

Introduction: Proper access to primary eye care is essential in addressing vision impairment, and tele-eye care examinations are a promising solution that could facilitate this access in many rural or remote areas. Even though remote eye exams are becoming increasingly frequent, comprehensive tele-eye care exams are still limited by the lack of published data. The aim of this study is to compare a comprehensive tele-eye care exam with a gold standard in-person primary eye care exam with an emphasis on refractive measurements, ocular health assessment, confidence level of the eye care providers and patient satisfaction. Methods: Sixty-six participants underwent two comprehensive eye exams performed by two eye care providers. One was a gold standard in-person exam, while the other was a remote exam performed by an eye care provider through videoconference. An overall patient satisfaction survey and a questionnaire for visual comfort with a trial frame from each modality were completed and the eye care providers scored their confidence level for each test. Exam results and diagnoses were compared between both modalities. Results: Tele-refraction has a good to excellent agreement with in-person subjective refraction in terms of sphero-cylindrical power and best corrected visual acuity. There was no statistically significant difference for visual comfort between both modalities. The agreement between in-person and remote exams for ocular health assessment ranged from fair to almost perfect, but there was a low prevalence of ocular pathologies within the study sample. The confidence level of the eye care providers and patient satisfaction were statistically higher in-person. Conclusion: Tele-eye care appears to be statistically and clinically non-inferior to in-person eye exams, especially for refraction, but the low prevalence of ocular pathologies somewhat limits the comparison of its efficacy for ocular health assessment. More studies on comprehensive tele-eye care exams are needed.

RESUMEN

Background: The purpose of this research was to compare patient satisfaction between hybrid ophthalmology telemedicine and standard-of-care in-person visits. A retrospective, cross-sectional, case-control analysis of patient satisfaction based on survey data was used. Methods: Responses to the National Research Council Health Patient Survey were retrieved for randomly sampled hybrid ophthalmology telemedicine and in-person visits between March 11, 2020 and December 31, 2021 at a hospital-based eye clinic in Boston, Massachusetts. The primary outcome was based on the question "How likely would you be to recommend this provider to your family and friends?" (0-10 scale) with a score of 9 or 10 coded as satisfied. Two-sample t-tests, Pearson's chi-square tests, and bivariate logistic regressions were used to compare patient satisfaction scores between the hybrid and in-person cohorts. Demographic data, including age, sex, language, and self-reported race and ethnicity, were used as potential predictors of patient satisfaction in a multivariable logistic regression model. Results: There were 49 surveys from hybrid visits and 3,390 surveys from in-person visits. Hybrid visit patients reported high satisfaction scores without significant differences compared to in-person visit patients (hybrid 79% satisfied, in-person 82% satisfied, p = 0.728). Age was significantly associated with satisfaction in the hybrid cohort with the 65+ age group reporting lower satisfaction (below 65 years 100% satisfied, 65+ years 60% satisfied, p = 0.003). No association with age was observed in the in-person cohort. Conclusions: The hybrid ophthalmology telemedicine model can provide effective care without sacrificing patient satisfaction. Older patients may benefit from targeted interventions in future telemedicine models.
