[Arterial hypertension and glaucoma: watch out for nocturnal blood pressure]
Abstract
Glaucoma is the second cause of blindness in industrialized countries. One of the principal risk factors for open angle glaucoma, the most prevalent form of the disease, is an increase in intraocular pressure (IOP). An excessive drop in nocturnal blood pressure (so called dipping) can be harmful by increasing ischemic damage to the optic nerve. In case of progression of glaucoma despite well controlled IOP, 24h BP monitoring is recommended. The relationship between IOP and systemic blood pressure has been the subject of several studies that are reviewed in this article. The influence of antihypertensive drugs on IOP is also discussed.
Le glaucome est la 2e cause de cécité dans les pays industrialisés. Un des principaux facteurs de risque du glaucome à angle ouvert, la forme la plus fréquente, est l’augmentation de la pression intraoculaire (PIO). Une baisse excessive de la pression artérielle (PA) pendant la nuit (dipping) favorise des processus ischémiques au niveau du nerf optique, qui jouent un rôle dans la progression du glaucome chez certains patients. En cas d’une progression du glaucome malgré une PIO satisfaisante, la mesure de la PA de 24 h est recommandée pour détecter l’hypotension nocturne. La relation entre la PIO et la pression artérielle systémique reste controversée, et est passée en revue dans cet article, tout comme les recherches ayant observé l’effet des différentes classes d’hypotenseurs sur la PIO.
