La zonule de Zinn (zonule ciliaire ou ligament suspenseur du cristallin), situ\u00e9e derri\u00e8re l’iris, est un syst\u00e8me circonf\u00e9rentiel de faisceaux de fibres qui relie le cristallin au corps ciliaire et qui est responsable du centrage du cristallin. La tension exerc\u00e9e par la zonule sur le cristallin est modul\u00e9e par la contraction ou le rel\u00e2chement du muscle ciliaire. <\/p>\n

La rupture des fibres zonulaires et la dislocation subs\u00e9quente du cristallin (ectopie lentis) peuvent r\u00e9sulter d’un traumatisme contondant ou \u00eatre une s\u00e9quelle d’autres maladies oculaires. La pseudoexfoliation, une forte myopie, des ant\u00e9c\u00e9dents de vitrectomie ou de trab\u00e9culectomie, l’uv\u00e9ite, la r\u00e9tinopathie du pr\u00e9matur\u00e9 ou l’aniridie sont des conditions qui entra\u00eenent une perturbation de la barri\u00e8re h\u00e9mato-aqueuse et peuvent conduire \u00e0 un affaiblissement des zonules. <\/p>\n

Les modifications des fibres zonulaires qui affectent la position et la forme du cristallin peuvent \u00eatre responsables de la pathogen\u00e8se du glaucome \u00e0 angle ferm\u00e9. En outre, une rupture des fibres zonulaires peut se produire avec un prolapsus interne du corps vitr\u00e9, sans dislocation du cristallin. Le vitr\u00e9 libre dans la chambre ant\u00e9rieure est presque transparent et sa pr\u00e9sence est d\u00e9tect\u00e9e par de fines particules de pigment pi\u00e9g\u00e9es dans ses mailles, qui se d\u00e9placent lors de l\u00e9gers mouvements de l’\u0153il. Le vitr\u00e9 libre est facilement reconnaissable dans la partie pupillaire de la chambre ant\u00e9rieure. <\/p>\n

Les anneaux de tension capsulaires et les dispositifs endocapsulaires associ\u00e9s sont utilis\u00e9s pour assurer une stabilisation suffisante du sac capsulaire et assurer la s\u00e9curit\u00e9 des proc\u00e9dures de chirurgie de la cataracte.<\/p>\n<\/div>\n
