The topic Stage 4 Hypertensive Retinopathy you are seeking is a synonym, or alternative name, or is closely related to the medical condition Hypertensive Retinopathy.

Quick Summary:

  • Hypertensive Retinopathy (HR) refers to abnormal changes of the retina that is located in the back of the eye, due to chronic hypertension (high blood pressure)
  • The retinal arteries are autoregulated, meaning they can control their own shape based on changes in systemic blood pressure. However, at extremely high blood pressures, such as a blood pressure of 140/110 mmHg or over, they are unable to autoregulate. This can result in retinal complications
  • Depending on the severity of the signs and symptoms, Hypertensive Retinopathy can be classified to 4 stages - stage 1, 2, 3, and 4. Stage 1 Hypertensive Retinopathy has mild signs and symptoms, whereas Stage 4 Hypertensive Retinopathy has severe signs and symptoms
  • These changes typically occur in individuals who have had very high blood pressure for several years. The signs and symptoms of Hypertensive Retinopathy may include leakage of fats from the blood vessels, retinal edema (fluid in the retina), and swelling of the optic nerves
  • Some of the complications can include lack of oxygen delivered to the retina, as well as swelling of the macula and optic nerve that can result in the vision being affected
  • The treatment typically consists of controlling systemic hypertension with medications. Prognosis is generally good for individuals with stage 1 or 2 Hypertensive Retinopathy
