Control of high blood pressure (hypertension) is the only treatment for hypertensive retinopathy.
Patients with grade IV (severe hypertensive retinopathy) frequently also have heart and kidney complications of high blood pressure. The retina will generally recover well if the blood pressure is controlled, but some patients with grade IV 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.
