Le glaucome<\/strong> est une maladie oculaire fr\u00e9quente et touche plus de 2% de la population au-del\u00e0 de 45 ans.<\/p>\n\n\n\n

En France, on estime qu\u2019il y a environ 1 million de personnes touch\u00e9es. Une telle fr\u00e9quence justifie que la mesure de la pression oculaire<\/strong> soit faite de mani\u00e8re r\u00e9guli\u00e8re, pendant un examen ophtalmologique.<\/p>\n\n\n\n

Il est conseill\u00e9 de voir son m\u00e9decin sp\u00e9cialiste tous les deux ans<\/strong> environ (\u00e0 partir de 45 ans) pour la r\u00e9alisation de ces mesures.<\/p>\n\n\n\n

Dans les pays d\u00e9velopp\u00e9s, le glaucome est la premi\u00e8re cause de c\u00e9cit\u00e9 absolue. Les autres causes fr\u00e9quentes de baisse de vue sont la d\u00e9g\u00e9n\u00e9rescence maculaire li\u00e9e \u00e0 l\u2019\u00e2ge et la cataracte. Ces deux maladies n\u2019ont pas de lien avec le glaucome mais peuvent exister chez des patients glaucomateux.<\/p>\n\n\n\n

Deux grandes formes<\/strong> de glaucome existent.<\/p>\n\n\n\n

Il s\u2019agit du glaucome \u00e0 angle ouvert<\/strong>, le plus fr\u00e9quent et du glaucome par<\/strong> fermeture de l\u2019angle<\/strong>.<\/p>\n\n\n\n

Le glaucome est d\u00fb \u00e0 une mont\u00e9e de la pression oculaire entra\u00eenant une atteinte du nerf optique<\/strong> (qui envoie les informations visuelles au cerveau) et du champ visuel<\/strong> (espace de vision).<\/p>\n\n\n\n

Le glaucome \u00e0 angle ouvert<\/strong> est li\u00e9 \u00e0 la fermeture progressive du filtre d\u2019\u00e9vacuation, le trab\u00e9culum<\/strong>. Ce ph\u00e9nom\u00e8ne est progressif car le patient ne ressent pas l\u2019augmentation lente de la pression oculaire.<\/p>\n\n\n\n

Le glaucome par fermeture de l\u2019angle<\/strong> est aussi appel\u00e9 glaucome aigu<\/strong>, est tr\u00e8s brutal. Il est li\u00e9 \u00e0 l\u2019accolement en quelques instants de l\u2019iris au filtre d\u2019\u00e9vacuation. Il est joint \u00e0 d\u2019importantes douleurs et \u00e0 une baisse de la vue. C\u2019est une grande urgence ophtalmologique.<\/p>\n\n\n\n

Par ailleurs, il existe aussi des glaucomes tr\u00e8s rares survenant d\u00e8s la naissance et appel\u00e9s glaucomes cong\u00e9nitaux.<\/strong> D\u2019embl\u00e9e, leur traitement est chirurgical.<\/p>\n\n\n\n

Enfin, un glaucome peut arriver \u00e0 la suite d\u2019une autre maladie de l\u2019\u0153il comme une inflammation ou un traumatisme.<\/strong><\/p>","protected":false},"excerpt":{"rendered":"
