title: [Macular edema in arterial hypertension].
abstract: Acute arterial hypertension causes 3 types of fundus anomalies: hypertensive retinopathy, hypertensive choroidopathy and hypertensive optic neuropathy. Hypertensive retinopathy and optic neuropathy are characterised by retinal and optic disc capillary and precapillary occlusions, and a rupture of the inner hemato-retinal barrier resulting in retinal edema. Hypertensive choroidopathy is characterized by areas of choriocapillaris occlusion resulting in necrosis of the pigment epithelium which causes a rupture of the outer hemato-retinal barrier and retinal edema.
