- W2045553611 abstract "Retinal prostheses aim at restoring visual perception in blind patients affected by retinal diseases leading to the loss of photoreceptors, such as age-related macular degeneration or retinitis pigmentosa. Recent clinical trials have demonstrated the feasibility of this approach for restoring useful vision. Despite a limited number of electrodes (60), and therefore of pixels, some patients were able to read words and to recognize high-contrast objects. Face recognition and independent locomotion in unknown urban environments imply technological breakthroughs to increase the number and density of electrodes. This review presents recent clinical results and discusses future solutions to answer the major technological challenges. Les prothèses rétiniennes ont pour objet de restaurer la perception visuelle de patients devenus aveugles dans des pathologies reposant sur la perte des photorécepteurs, comme la dégénérescence maculaire liée à l’âge ou la rétinopathie pigmentaire. Les essais cliniques récents ont démontré la faisabilité de cette approche pour redonner une certaine vision. Malgré un nombre limité d’électrodes (60) et donc a fortiori de pixels, certains patients étaient en mesure de lire des mots ou de reconnaître des objets très contrastés. Le retour à l’autonomie pour la locomotion en milieu urbain inconnu ou la reconnaissance des visages impose des sauts technologiques pour augmenter le nombre et la densité des électrodes. Cette revue expose les résultats récents des essais cliniques et discute les solutions d’avenir envisagées pour résoudre les défis technologiques posés." @default.
