Screening for ocular anomalies using fundus photography is key to prevent vision impairment and blindness. With the growing and aging population, automated algorithms that can triage fundus photographs and provide instant referral decisions are relevant to scale-up screening and face the shortage of ophthalmic expertise.
PURPOSE
This study aimed to develop a deep learning algorithm that detects any ocular anomaly in fundus photographs and to evaluate this algorithm for “normal versus anomalous” eye examination classification in the diabetic and general populations.
METHODS
The deep learning algorithm was developed and evaluated in two populations: the diabetic and general populations. Our patient cohorts consist of 37,129 diabetic patients from the OPHDIAT diabetic retinopathy screening network in Paris, France, and 7356 general patients from the OphtaMaine private screening network, in Le Mans, France. Each data set was divided into a development subset and a test subset of more than 4000 examinations each. For ophthalmologist/algorithm comparison, a subset of 2014 examinations from the OphtaMaine test subset was labeled by a second ophthalmologist. First, the algorithm was trained on the OPHDIAT development subset. Then, it was fine-tuned on the OphtaMaine development subset.
RESULTS
On the OPHDIAT test subset, the area under the receiver operating characteristic curve for normal versus anomalous classification was 0.9592. On the OphtaMaine test subset, the area under the receiver operating characteristic curve was 0.8347 before fine-tuning and 0.9108 after fine-tuning. On the ophthalmologist/algorithm comparison subset, the second ophthalmologist achieved a specificity of 0.8648 and a sensitivity of 0.6682. For the same specificity, the fine-tuned algorithm achieved a sensitivity of 0.8248.
CONCLUSIONS
The proposed algorithm compares favorably with human performance for normal versus anomalous eye examination classification using fundus photography. Artificial intelligence, which previously targeted a few retinal pathologies, can be used to screen for ocular anomalies comprehensively.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Rétinopathie diabétiqueRésumé : SIGNIFICANCE: Optometrists play a preventive role in diabetic care by detecting early signs of diabetic retinopathy (DR), a leading cause of blindness in adults. This study demonstrates that additional training can improve optometrists' ability to assess the presence and severity of DR in individuals with diabetes. PURPOSE: This study aimed to determine the impact of a quality improvement intervention involving education, assessment, and feedback on improving the evaluation and referral patterns of optometrists with regard to their patients with diabetes. METHODS: A pre-interventional and post-interventional analysis of optometrist practices was conducted through a retrospective chart review of diabetic patient encounters from July 2018 to March 2019. Dilated fundus examination (DFE) documentation, follow-up scheduling, referral practices, and usage of various imaging modalities were collected from patient records. Concordance of DR severity recordings between DFE findings, assessment and plan notes, and International Classification of Diseases codes was calculated. RESULTS: After intervention, the proportion of optometrists who conducted a DFE significantly increased from 79.5 (95% confidence interval [CI], 77.3 to 81.7%) to 84.4% (95% CI, 82.4 to 86.4%). In addition, the rate of improper follow-up instructions decreased from 13.8 (95% CI, 12.0 to 15.7%) to 10.8% (95% CI, 9.2 to 12.6%), and the decrease was significant (P = .02). Although overall referrals decreased from 19.8 (95% CI, 17.6 to 21.9%) to 14.6% (95% CI, 12.6 to 16.5%), optometrists were as likely to refer to retinal specialists. Finally, concordance between documented DFE findings, assessment and plan notes, and International Classification of Diseases codes significantly increased from 78.8 (95% CI, 76.5 to 81.0%) to 88.7% (95% CI, 86.9 to 90.4%). CONCLUSIONS: Providing optometrists education in screening and assessing DR is effective in improving diabetic patient care.

[Thésaurus Mesh]Troubles de la réfraction oculaire
[Thésaurus Mesh]Troubles de la visionRésumé : SIGNIFICANCE Uncorrected refractive error is the leading cause of visual impairment; therefore, reducing its prevalence is important worldwide. For two decades, there has not been a comprehensive assessment of refractive error in Latin America.
PURPOSE The purpose of this study was to determine the current prevalence of refractive error, presbyopia, spectacle coverage, barriers to uptake refractive services, and spectacle correction in people 15 years and older in Bogotá, Colombia.
METHODS A cross-sectional community-based survey was conducted using 50 randomly selected clusters from 10 districts of Bogotá reflecting the socioeconomic status of the city. Respondents 15 years and older were interviewed and underwent standardized clinical eye examinations. Prevalence of uncorrected refractive error, spectacle coverage, and visual impairment were standardized to 2015 age-sex population distribution of Bogotá and further analyzed.
RESULTS A total of 2886 subjects (90% of 3206 eligible subjects) participated in the study; 39.1% were male and 60.9% were female in the age range of 15 to 96 years, with a median age of 46 years (interquartile range, 45 to 54 years). Age- and sex-standardized prevalence of visual impairment was 19.3% (95% confidence interval [CI], 17.8 to 20.8%). Prevalence of uncorrected refractive error was 12.5% (95% CI, 11.3 to 13.7%). Prevalence of presbyopia among participants 35 years and older was 55.2% (95% CI, 52.9 to 57.4%). Spectacle coverage was 50.9% for distance vision, and it was 33.9% for presbyopia. Main barrier to spectacle uptake was a limitation in affording spectacles because of economic factors (29.5%).
CONCLUSIONS This study provides a current estimate of refractive error using the Rapid Assessment of Refractive Error for Colombia and the Latin American region. The prevalence of uncorrected refractive error and presbyopia was high, and the barriers to spectacle uptake were higher in the lowest socioeconomic strata. The results obtained in the present study will help in making evidence-based decisions related to eye care service delivery in Colombia.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Tomographie par cohérence optiqueMots-clés : photocoagulation panrétinienne Résumé : Le dépistage et le suivi ophtalmologique régulier des patients atteints de rétinopathie diabétique rendent la cécité évitable dans la plupart des cas.
La rétinopathie diabétique est une maladie dont le dépistage change véritablement le pronostic fonctionnel pour le patient. Il rend la cécité évitable. Le dépistage par rétinographie et/ou fond d'oeil annuel pour tous les diabétiques n'est pas encore assez systématique, et la Haute Autorité de santé cherche à développer des programmes de dépistage par télémédecine au niveau régional. Le traitement de la rétinopathie diabétique repose sur le traitement de ses deux complications majeures qui peuvent coexister : la prolifération néovasculaire, et l'oedème maculaire diabétique. Ces deux complications nécessitent une prise en charge préventive par un contrôle strict de la glycémie, de la pression artérielle et de l'hyperlipidémie. Une fois la complication avérée, la photocoagulation panrétinienne reste le traitement des néovaisseaux et les injections d'anti-VEGF, voire de corticoïdes, ceux de l'oedème maculaire diabétique. La chirurgie devient inévitable pour les formes compliquées, comme les hémorragies intravitréennes, les décollements de rétine ou le glaucome néovasculaire.Types de publication (MeSH) : Article de périodique Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
