La \u00ab\u00a0valve Ahmed\u00a0\u00bb?<\/strong><\/h3>\n

Le glaucome <\/strong>ne peut \u00eatre r\u00e9solu <\/strong>qu’en abaissant <\/strong>la pression intraoculaire<\/strong>. La \u00ab\u00a0valve Ahmed<\/strong>\u00a0\u00bb maintient <\/strong>cette pression <\/strong>de mani\u00e8re permanente, via une petite plaque<\/strong> avec un m\u00e9canisme de valve unique<\/strong>. Cette plaque est \u00e0 son tour connect\u00e9e <\/strong>\u00e0 un tube de drainage<\/strong> qui \u00e9limine l’exc\u00e8s<\/strong> de liquide<\/strong> dans l’\u0153il et abaisse ainsi la pression oculaire<\/strong> au niveau souhait\u00e9<\/strong>. Une fois implant\u00e9e, la pression de l\u2019humeur acqueuse<\/strong> dans l’\u0153il et la fonction de la valve continuent \u00e0 interagir<\/strong>, emp\u00eachant <\/strong>\u00e0 la fois une d\u00e9charge excessive<\/strong>, aussi bien que la surpression<\/strong>.<\/p>\n

Historique<\/h4>\n

La diminution <\/strong>de la pression intra-oculaire<\/strong> est la seule m\u00e9thode efficace pour \u00e9viter la perte de vision<\/strong> pour les patients atteints de glaucome<\/strong>. Les patients <\/strong>atteints d’une forme l\u00e9g\u00e8re<\/strong> de glaucome <\/strong>peuvent d\u00e9j\u00e0 \u00eatre aid\u00e9s avec un collyre <\/strong>sp\u00e9cifique. Si cette solution n’est pas adapt\u00e9e<\/strong> ou si un glaucome plus s\u00e9v\u00e8re <\/strong>se manifeste, le traitement au laser<\/strong> ou par chirurgie <\/strong>est souvent l\u2019\u00e9tape suivante.<\/p>\n

Bien que chaque type de chirurgie<\/strong> comporte un risque de complications post-op\u00e9ratoire, cette approche est la plus efficace<\/strong> dans le traitement <\/strong>du glaucome r\u00e9fractaire<\/strong>.<\/p>\n

Pourquoi la \u00ab\u00a0Valve Ahmed\u00a0\u00bb?<\/h4>\n

Il existe plusieurs implants similaires aujourd’hui. Seule la Valve Ahmed\u00ae<\/sup> (AGV\u2122) <\/strong>offre une solution \u00e0 long terme<\/strong> pour la baisse de PIO avec une satisfaction \u00e9lev\u00e9e<\/strong>.1<\/sup> Bien que l’implant <\/strong>se trouve \u00e0 l’ext\u00e9rieur de l’\u0153il<\/strong>, il est invisible <\/strong>car il est recouvert par la conjonctive autour de l’\u0153il et reste donc cach\u00e9. De plus, il n’est \u00e9galement pas ressenti par le patient.<\/p>\n

Quand est-il recommand\u00e9?<\/h4>\n

La \u00ab\u00a0Valve Ahmed\u00a0\u00bb est recommand\u00e9e <\/strong>dans les cas de glaucome r\u00e9fractaire<\/strong>, en particulier lorsque d’autres interventions chirurgicales<\/strong> ont \u00e9chou\u00e9es ou lorsque l\u2019on consulte la litt\u00e9rature qui semble montrer que les traitements chirurgicaux alternatifs n\u2019offrent pas de r\u00e9sultats positifs. Plus sp\u00e9cifiquement dans les cas suivants<\/strong> de glaucomes r\u00e9fractaires<\/strong>:<\/p>\n

    \n
  • Glaucome n\u00e9ovasculaire;<\/li>\n
  • Glaucome primitif \u00e0 angle ouvert (ne r\u00e9pondant pas aux m\u00e9dicaments);<\/li>\n
  • Glaucome cong\u00e9nital;<\/li>\n
  • Glaucome p\u00e9diatrique;<\/li>\n
  • Glaucome r\u00e9fractaire caus\u00e9 par l’aphakie2<\/sup> ou l’uv\u00e9ite.<\/li>\n<\/ul>\n
