Abstract[English]
Described herein is a method for replacing retinal tissue with retinal cell- embedded biodegradable matrix ribbons. The biodegradable matrix ribbons can be provided as a sheet and subsequently cut into ribbons. Alternatively, the biodegradable matrix ribbons can be constructed in ribbon form. The thin ribbons can then be implanted into a patient's eye through small scleral and/or retinal incisions. Once inside the ocular space, the ribbons can be positioned at a target retinal space in a confluent fashion in order to provide an area of biodegradable matrix having retinal cells embedded within and on outer surfaces thereof.[French]
L'invention concerne une méthode de remplacement de tissu rétinien par des rubans de matrice biodégradables incorporés dans des cellules rétiniennes. Les rubans de matrice biodégradables peuvent être fournis sous la forme d'une feuille et ensuite coupés en rubans. En variante, les rubans de matrice biodégradables peuvent être construits sous forme de ruban. Les rubans minces peuvent ensuite être implantés dans l'œil d'un patient par l'intermédiaire de petites incisions sclérales et/ou rétiniennes. Une fois à l'intérieur de l'espace oculaire, les rubans peuvent être positionnés au niveau d'un espace rétinien cible d'une manière confluente afin de fournir une zone de matrice biodégradable ayant des cellules rétiniennes incorporées à l'intérieur et sur des surfaces externes de celle-ci.
