Controlling high blood pressure (hypertension) is the only treatment for hypertensive retinopathy.
See also: Malignant hypertension for treatment of this disorder
Patients with grade 4 (severe hypertensive retinopathy) often have heart and kidney complications of high blood pressure. They are also at higher risk for stroke.
The retina will generally recover if the blood pressure is controlled. However, some patients with grade 4 hypertensive retinopathy will have permanent damage to the optic nerve or macula.
Go to the emergency room or call the local emergency number (such as 911) if you have high blood pressure and vision changes or headaches occur.
