Wat is “Glaucoma Valve”?<\/strong><\/h3>\n

Glaucoom<\/strong>\u00a0kan enkel\u00a0verholpen<\/strong>\u00a0worden door de\u00a0druk intraoculair<\/strong>\u00a0te\u00a0verlagen<\/strong>. Een zogeheten \u201cglaucoma valve<\/strong>\u201d\u00a0regelt<\/strong>\u00a0blijvend die\u00a0druk<\/strong>, via een\u00a0klein plaatje<\/strong>\u00a0met uniek\u00a0klepmechanisme<\/strong>.\u00a0Dit plaatje is op zijn beurt\u00a0verbonden<\/strong>\u00a0met een\u00a0drainagebuisje<\/strong>\u00a0dat het\u00a0teveel<\/strong>\u00a0aan\u00a0vloeistof afvoert<\/strong>\u00a0uit het oog en op die manier de te hoge\u00a0oogdruk<\/strong>\u00a0gaat verlagen naar het\u00a0gewenste niveau<\/strong>.\u00a0Eens ge\u00efmplanteerd blijven de\u00a0vloeistofdruk<\/strong>\u00a0in het oog en de\u00a0klepfunctie samenwerken<\/strong>, wat zowel\u00a0excessieve afvoer<\/strong>\u00a0als\u00a0teveel<\/strong>\u00a0aan\u00a0druk voorkomt<\/strong>.<\/p>\n

Geschiedenis<\/h4>\n

Het\u00a0verlagen<\/strong>\u00a0van\u00a0intraoculaire druk<\/strong>\u00a0is de enige doeltreffende methode om\u00a0zichtverlies<\/strong>\u00a0bij\u00a0glaucoom pati\u00ebnten<\/strong>\u00a0te\u00a0voorkomen<\/strong>.\u00a0Pati\u00ebnten met een\u00a0milde vorm<\/strong>\u00a0van\u00a0glaucoom<\/strong>\u00a0kunnen al geholpen zijn met behulp van een specifieke\u00a0oogdruppel<\/strong>. Wanneer deze\u00a0oplossing niet geschikt<\/strong>\u00a0is of wanneer een\u00a0ernstigere graad<\/strong>\u00a0van glaucoom optreedt, is een\u00a0laserbehandeling<\/strong>\u00a0of\u00a0chirurgie<\/strong>\u00a0vaak de volgende stap.<\/p>\n

Hoewel elk type chirurgie een risico op complicaties met zich meedraagt, is de\u00a0chirurgische benadering<\/strong>\u00a0in de praktijk de\u00a0meest effici\u00ebnte<\/strong>\u00a0bij een\u00a0weerspannig<\/strong>\u00a0of\u00a0refractair glaucoom<\/strong>.<\/p>\n

Waarom Ahmed Valve?<\/h4>\n

Er bestaan vandaag verschillende soortgelijke implantaten. Enkel de\u00a0Ahmed\u00ae<\/sup>\u00a0Glaucoma Valve<\/strong>\u00a0(AGV\u2122) biedt een\u00a0langetermijnoplossing<\/strong>\u00a0van de oogdruk met\u00a0hoge tevredenheidsfactor<\/strong>.1\u00a0<\/sup>Hoewel het\u00a0implantaat<\/strong>\u00a0zich\u00a0buiten het oog<\/strong>\u00a0bevindt, is het\u00a0onzichtbaar<\/strong>\u00a0omdat het door de huid rond het oog bedekt en dus verborgen blijft. Bovendien is het evenmin voelbaar voor de pati\u00ebnt.<\/p>\n

Wanneer aangeraden?<\/h4>\n

De “Ahmed Glaucoma Valve” wordt\u00a0aanbevolen<\/strong>\u00a0in geval van\u00a0refractair glaucoom<\/strong>, in het bijzonder wanneer\u00a0andere chirurgische ingrepen geen succes<\/strong>\u00a0kenden of wanneer uit de literatuur gebleken is dat alternatieve chirurgische behandelingen geen positieve resultaten opleveren. Meer specifiek in\u00a0volgende gevallen<\/strong>\u00a0van\u00a0weerspannige glaucoma’s<\/strong>:<\/p>\n

    \n
  • Neovasculaire glaucoma;<\/li>\n
  • Primaire open hoek glaucoom (niet responsief op medicatie);<\/li>\n
  • Congenitale glaucoom;<\/li>\n
  • Infantiele glaucoom;<\/li>\n
  • Refractair glaucoom die het gevolg is van aphakia2<\/sup>\u00a0of uveitis.<\/li>\n<\/ul>\n
