En partie 1<\/a> nous avons expliqu\u00e9 comment les l\u00e9sions de la r\u00e9tine peuvent augmenter les risques de d\u00e9g\u00e9n\u00e9rescence maculaire (DM).<\/p>\n\n\n\n

Qu'est-ce que la d\u00e9g\u00e9n\u00e9rescence maculaire ?
Dans nos maculas, nous avons des cellules pigmentaires, comme dans notre peau. Les pigments absorbent les radiations nocives qui peuvent endommager nos r\u00e9tines. Lorsque nos r\u00e9tines cessent de fonctionner correctement, ces cellules pigmentaires peuvent cesser de traiter les lipides, ce qui entra\u00eene leur accumulation. Avec le temps, cela peut endommager les r\u00e9cepteurs de lumi\u00e8re dans les yeux, ce qui entra\u00eene une diminution de la vision centrale. On parle alors de d\u00e9g\u00e9n\u00e9rescence maculaire.<\/p>\n\n\n\n

Deux types de d\u00e9g\u00e9n\u00e9rescence maculaire<\/p>\n\n\n\n

Secs
Il existe deux types de d\u00e9g\u00e9n\u00e9rescence maculaire : la d\u00e9g\u00e9n\u00e9rescence s\u00e8che et la d\u00e9g\u00e9n\u00e9rescence humide. La d\u00e9g\u00e9n\u00e9rescence maculaire s\u00e8che progresse g\u00e9n\u00e9ralement plus lentement et le risque de perte soudaine et profonde de la vision est moindre. Toutefois, \u00e0 mesure qu'elle progresse, elle peut toujours entra\u00eener une c\u00e9cit\u00e9 de la vision centrale, mais pas aussi rapidement que le type humide. L'image ci-dessus montre un scanner oculaire des couches d'une macula atteinte de d\u00e9g\u00e9n\u00e9rescence maculaire s\u00e8che. Les lignes ondul\u00e9es orange et rouge sont des drusen, qui sont des d\u00e9bris lipidiques accumul\u00e9s et qui peuvent entra\u00eener une baisse de la vision.<\/p>\n\n\n\n

Humide
Nous l'appelons humide parce que les vaisseaux sanguins se d\u00e9veloppent dans les zones qui bloquent notre vision, et qu'ils sont fragiles et peuvent fuir, entra\u00eenant la pr\u00e9sence de liquide et de sang dans nos r\u00e9tines. Cette forme humide est plus agressive et entra\u00eene g\u00e9n\u00e9ralement une aggravation plus rapide de la vision centrale.<\/p>\n\n\n\n

Traitement
Pour la DM s\u00e8che, il n'existe pas de traitement efficace. Pour la forme humide, certaines injections oculaires peuvent aider \u00e0 r\u00e9duire la gravit\u00e9 de la fuite des vaisseaux sanguins dans la r\u00e9tine, et certaines th\u00e9rapies \u00e0 base de cellules souches peuvent aider, mais elles n'inversent pas les dommages caus\u00e9s.<\/p>\n\n\n\n

La pr\u00e9vention
\u00c9tant donn\u00e9 qu'il n'existe aucun traitement permettant de gu\u00e9rir ou d'\u00e9liminer les dommages caus\u00e9s par la DM, nous devons tout mettre en \u0153uvre pour r\u00e9duire nos facteurs de risque. La polyarthrite rhumato\u00efde est h\u00e9r\u00e9ditaire, mais nous ne pouvons pas changer nos g\u00e8nes, ce qui est donc hors de notre contr\u00f4le. Cela ne signifie pas que vous l'aurez si vous avez des ant\u00e9c\u00e9dents familiaux, mais cela signifie que vous avez plus de risques de l'avoir. Les autres facteurs de risque sont le tabagisme, l'ob\u00e9sit\u00e9 et l'exposition au soleil. Il a \u00e9t\u00e9 d\u00e9montr\u00e9 que le r\u00e9gime alimentaire a \u00e9galement une incidence sur le risque de DM. Il a \u00e9t\u00e9 d\u00e9montr\u00e9 que la prise d'un suppl\u00e9ment de z\u00e9axanthine et de lut\u00e9ine r\u00e9duisait le risque. Il existe de nombreuses vitamines pour les yeux sur le march\u00e9. Certaines sont excellentes, d'autres moins. Consultez Sant\u00e9 de la r\u00e9tine Partie 3<\/a> pour plus de d\u00e9tails sur les aliments et les compl\u00e9ments que je recommande pour maximiser la sant\u00e9 de vos r\u00e9tines.<\/p>\n\n<\/div>\n\n<\/div>","protected":false},"excerpt":{"rendered":"
