La Siderosis Bulbi est caus\u00e9e par la r\u00e9tention et l’oxydation d’un corps \u00e9tranger contenant du fer dans le globe oculaire, ce qui entra\u00eene un d\u00e9p\u00f4t de fer dans les structures \u00e9pith\u00e9liales intraoculaires (\u00e9pith\u00e9lium du cristallin, iris, corps ciliaire et r\u00e9tine sensorielle) o\u00f9 il a un effet toxique sur les syst\u00e8mes enzymatiques cellulaires et par cons\u00e9quent la mort cellulaire. La pr\u00e9sentation clinique comprend la cataracte, d\u00e9p\u00f4ts sous-capsulaires post\u00e9rieurs de couleur rouille, h\u00e9t\u00e9rochromie de l’iris avec d\u00e9coloration brun\u00e2tre, pupille dilat\u00e9e et non r\u00e9actif et un \u00e9lectror\u00e9tinogramme avec des amplitudes r\u00e9duites. D’autres cons\u00e9quences potentielles comprennent la r\u00e9tinopathie pigmentaire, microangiopathie r\u00e9tinienne et glaucome \u00e0 angle ouvert.<\/p>\n

La sid\u00e9rose peut se d\u00e9velopper en quelques semaines, mais pr\u00e9sente un parcours variable qui d\u00e9pend de la quantit\u00e9 de fer pr\u00e9sente dans le corps \u00e9tranger et de son emplacement. Toutes les structures peuvent \u00eatre impliqu\u00e9es dans le processus sid\u00e9rotique Les changements fonctionnels apparaissent \u00e0 un stade pr\u00e9coce avant que la sid\u00e9rosis ne soit visible et que le fer soit d\u00e9tectable dans les tissus r\u00e9tiniens. L\u2019accumulation de fer intracellulaire entra\u00eene une d\u00e9g\u00e9n\u00e9rescence de la r\u00e9tine interne et de l\u2019\u00e9pith\u00e9lium pigment\u00e9 de la r\u00e9tine, suivie d\u2019une d\u00e9g\u00e9n\u00e9rescence de toute l\u2019\u00e9paisseur de la r\u00e9tine et de la gliose. La d\u00e9g\u00e9n\u00e9rescence du vitr\u00e9 associ\u00e9e \u00e0 une d\u00e9g\u00e9n\u00e9rescence r\u00e9tinienne peut causer un d\u00e9collement de r\u00e9tine.<\/p>\n<\/div>\n

En sid\u00e9rose, l’\u00e9pith\u00e9lium du cristallin a une couleur jaune brun\u00e2tre ou couleur rouille due \u00e0 la pr\u00e9sence de fer intracellulaire.<\/p>\n

Le corps \u00e9tranger intraoculaire doit \u00eatre extrait le plus t\u00f4t possible pour \u00e9viter une siderose Bulbi irr\u00e9versible. S’il n’y a pas d’oed\u00e8me maculaire apr\u00e8s l\u2019extraction du corps \u00e9tranger et de la cataracte, le pronostic visuel est bon.<\/p>\n<\/div>\n
