Abstract

La présente invention concerne une microsphère injectable comprenant un principe actif pour le traitement d'un trouble oculaire, par exemple la dégénérescence maculaire de forme humide, et qui offre une libération contrôlée du principe actif sur une période de temps prolongée, ce qui permet une réduction de la fréquence d'injection par rapport aux traitements connus.
