  • Etiology Clinical features Hypertension is usually asymptomatic until complications of end-organ damage arise or an acute increase in blood pressure occurs (see hypertensive urgency below).[amboss.com]
  • Epidemiology and Etiology The prevalence is uncertain. Cotton-wool spots are seen in over 40% of cases of diabetic retinopathy and also with acute systemic arterial hypertension. No hereditary pattern is known.[entokey.com]
  • Regardless of etiology, acutely or chronically elevated blood pressures can damage the eye, and in particular, the retina. Hypertensive retinopathy is the result of changes to the retinal vasculature in high blood pressure states.[morancore.utah.edu]

  • Prevention The importance of having an examination of the fundus in hypertension patients, age and the presence of other cardiovascular risk factors makes it necessary to follow periodic monitoring from an ophthalmologist, for an examination of the fundus[barraquer.com]
