La r\u00e9tinopathie hypertensive est caract\u00e9ris\u00e9e par l\u2019 alt\u00e9ration de la vascularisation de la r\u00e9tine caus\u00e9e par l\u2019 hypertension art\u00e9rielle s\u00e9v\u00e8re maintenue. La tension art\u00e9rielle \u00e9lev\u00e9e provoque une constriction focale et aussi g\u00e9n\u00e9ralis\u00e9e des art\u00e9rioles r\u00e9tiniennes due \u00e0 l\u2019autor\u00e9gulation du flux sanguin. <\/p>\n

Les alt\u00e9rations du fond d\u2019\u0153il provoqu\u00e9es par l\u2019\u00e9l\u00e9vation chronique de la pression art\u00e9rielle et les alt\u00e9rations d\u00e9g\u00e9n\u00e9ratives de la paroi art\u00e9riolaire incluent l’att\u00e9nuation des art\u00e9rioles r\u00e9tiniennes, des alt\u00e9rations du reflex art\u00e9riolaire et des croisements art\u00e9rio-veineux. L’augmentation de la perm\u00e9abilit\u00e9 vasculaire peu causer d\u00e9p\u00f4ts lipidiques (exsudats durs) et h\u00e9morragies en flamme de bougie. Les changements h\u00e9modynamiques dans l\u2019hypertension art\u00e9rielle peuvent causer occlusion vasculaire, isch\u00e9mie focale et infarctus de la couche de fibres nerveux (nodules cotonneux).<\/p>\n

Une \u00e9l\u00e9vation marqu\u00e9e et aigu\u00eb de la pression art\u00e9rielle peut entra\u00eener une r\u00e9tinopathie hypertensive aigu\u00eb (hypertension maligne) et une choro\u00efdopathie hypertensive. Zones d’infarctus de la r\u00e9tine peuvent survenir comme l\u00e9sions hyper-pigment\u00e9es avec un halo d’hyperpigmentation \u2013 taches d\u2019Elschnig. Les infarctus de la choro\u00efde apparaissent souvent avec une configuration hyper-pigment\u00e9e le long d’un m\u00e9ridien \u2013 stries de Siegrist.<\/p>\n

L\u2019hypertension maligne est associ\u00e9e \u00e0 l\u2019\u0153d\u00e8me et aux h\u00e9morragies r\u00e9tiniennes p\u00e9ripapillaires.<\/p>\n
