[PDF] drusen

Les drusen, ou druses, sont des dépôts de matériel amorphe dans la rétine situés dans la couche cuticulaire de la membrane de Bruch au contact de l’épithélium pigmenté. Ils sont le facteur principal de l’apparition de néo-vaisseaux. On distingue WikipédiaAutres questions

  • C'est quoi les Drusens ?

    drusen n.f.p. Dépôt de substance hyaline sur l'épithélium pigmenté de la rétine. drusen de la membrane de Bruch l.m.p.
    Taches visibles sous l'épithélium pigmentaire rétinien, jaunâtres, plus ou moins larges, apparaissant, disparaissant, se modifiant et évoluant vers l'extension.

  • Comment soigner les Drusens ?

    Il n'y a aucun traitement pour les drusen du nerf optique.
    Néanmoins, une surveillance des champs visuels est essentielle afin de détecter une éventuelle péjoration du déficit du champ visuel.

  • Qu'est-ce qu'un drusen papillaire ?

    Ces drusen (ou druses) représentent des dépôts anormaux de matériel protéinique au niveau de la papille optique – la partie antérieure du nerf optique.
    La cause exacte de leur présence reste inconnue.
    On pense que les drusen du nerf optique résultent d'une anomalie du flux de matériel dans les cellules du nerf optique.

  • Qu'est-ce qu'un drusen papillaire ?

    Il existe peu de traitements contre la dégénérescence maculaire sèche, mais cette maladie progresse très lentement et ne masque jamais entièrement la vision centrale.
    Lors de dégénérescence maculaire humide, les traitements les plus récents empêchent le développement des vaisseaux sanguins anormaux sur la rétine.
