Abstract

ABSTRACT
We report the case of a well-controlled 75-year-old hypertensive patient, brought for emergency care by his son for non-specific visual disorders. Clinical assessment evoked cortical blindness. A cerebral computed tomography (CT) and an angio-scanner of the supra-aortic vessels were requested revealing ischemic lesions on the territories of the posterior cerebral arteries related to basilar trunk stenosis. The peculiarity of this case is the occurrence of cortical blindness despite the good control of high blood pressure, which appears to be the only risk factor, and the absence of vision recovery after 13 months of follow-up, which is exceptional according to the literature.

RÉSUMÉ
Nous rapportons le cas d’un patient de 75 ans hypertendu bien contrôlé amené en urgence par son fils pour des troubles visuels non spécifiques. L’évaluation ophtalmologique a permis d’évoquer une cécité corticale. Une Tomodensitométrie cérébral et une angio-scanner des vaisseaux supra-aortiques ont été demandés révélant des lésions ischémiques sur les territoires des artères cérébrales postérieures en rapport avec une sténose du tronc basilaire. La particularité de ce cas est la survenue de cécité corticale malgré la bonne maîtrise de l'hypertension artérielle, qui semble être le seul facteur de risque, et l'absence totale de récupération fonctionnelle après 13 mois de suivi, ce qui est exceptionnel selon la littérature.
