Portrait

Expertise de recherche

Le Dr Renaud Duval a obtenu son doctorat en médecine de l'Université McGill et sa résidence en ophtalmologie de l'Université de Montréal. Il a complété un fellowship en chirurgie vitréo-rétinienne à Chicago, dans l'Illinois, à l'Université Rush et à Illinois Retina Associates. Il est un ophtalmologiste certifié et spécialisé dans la prise en charge des maladies médicales et chirurgicales de la rétine. Il est actuellement professeur adjoint au Département d'ophtalmologie de la Faculté de médecine de l'Université de Montréal. Il est directeur des fellowships en ophtalmologie à l'Université de Montréal. Il a une pratique chirurgicale très active en tant que chef de la rétine au Centre universitaire d’ophtalmologie - Hôpital Maisonneuve-Rosemont où il voit des patients, opère, enseigne aux étudiants en médecine et aux résidents et forme des boursiers en vitréo-rétine.
 
Il a co-écrit un chapitre de livre sur la vitrectomie pour la réparation des décollements de la rétine et a publié de nombreux articles évalués par des pairs. Il a présenté à plusieurs conférences internationales. Il a participé à 6 essais cliniques en tant que chercheur principal ou co-investigateur. Il a remporté de nombreux prix pour ses vidéos chirurgicales, qui ont été présentées localement et internationalement. Ses intérêts de recherche comprennent la dégénérescence maculaire liée à l'âge, la rétinopathie diabétique, l'intégration d'algorithmes d'apprentissage profond pour l'analyse des images du fond d'œil et des OCT, la télé-ophtalmologie et l'innovation chirurgicale à travers le développement de nouveaux outils chirurgicaux.
